Stainless Steel Headrest Knob – 6mm thread

Restore the finishing touches of your classic Porsche interior with this OE Match Stainless Steel Headrest Knob. Precision manufactured to complement the original factory design, this high-quality replacement knob is the ideal solution for replacing worn, damaged or missing headrest adjustment hardware on Porsche 356, 911 and 912 models.

Fits:

• Porsche 911 1965-1968 2.0L / 912 SWB (F)
• Porsche 356A 1955-59
• Porsche 356B 1959-63
• Porsche 356C 1963-65

Although small, the headrest knob is a prominent interior component that contributes to both the appearance and functionality of your seats. Over decades of use, original knobs can become scratched, corroded, dented or lost during seat refurbishment. Replacing them with a quality OE Match component helps restore the authentic look of your Porsche interior while ensuring smooth and reliable headrest adjustment.

Manufactured from durable stainless steel, this replacement headrest knob offers excellent corrosion resistance, long-lasting durability and an attractive factory-style finish, making it ideal for concours restorations, sympathetic refurbishments and everyday classic Porsche ownership.

What Does the Headrest Knob Do?

The headrest knob forms part of the seat adjustment mechanism, allowing the headrest to be securely adjusted or removed when required. It provides a comfortable grip for operation while maintaining the clean, period-correct appearance of the seat.

Why Replace the Headrest Knob?

Years of regular use and exposure can lead to deterioration of interior hardware. Common reasons for replacement include:

• Scratched or worn finish
• Corrosion or surface pitting
• Dented or damaged knob
• Missing original component
• Seat restoration or upholstery replacement
• Completing a concours-standard interior refurbishment

Replacing worn seat hardware is an effective way to improve both the appearance and usability of your Porsche interior.

Features

• Precision manufactured from high-quality stainless steel
• Corrosion-resistant finish
• Factory-style appearance
• Durable construction for long service life
• Smooth operation of the headrest adjustment mechanism
• Ideal for restoration and refurbishment projects
• Easy installation using the original mounting arrangement

Manufactured to complement the original factory design, these components help preserve the character of classic Porsche interiors while offering the durability expected from modern manufacturing techniques. Whether you're completing a full restoration or replacing individual trim pieces, OE Match parts provide an ideal balance of originality and reliability.

Inner cover seat recliner mechanism. 
This OE Match inner cover is a replacement trim component designed for the seat recliner mechanism on classic Porsche 911 and 912 models 1968. It fits over the internal seat hinge mechanism and restores the original appearance and protection of the seat recliner assembly. This OE Match part is manufactured to replicate the original Porsche design for proper fit and period-correct interior restoration.
Sold as a pair for one seat - 2 pairs required per car

Fits:
Porsche 911 / 912 - 1968

Diagram ref no 26

The inner cover shields the seat recliner mechanism from dirt and debris while also improving the appearance of the seat hinge area. By enclosing the mechanism, it helps protect internal moving components and ensures the seat adjustment system operates smoothly without obstruction.

Replacing worn covers helps restore the original interior finish of classic Porsche seats and prevents further damage to the recliner mechanism.

Seat recliner covers are often exposed to wear from seat movement, UV exposure and aging plastics. Over time they may crack, break or become brittle, leaving the recliner mechanism exposed. Installing a new OE Match cover restores the original look of the interior and protects the seat adjustment mechanism from damage.

Replace the recliner mechanism cover if you notice:
•  Cracked or broken seat hinge covers
•  Missing trim around the seat recliner mechanism
•  Loose or exposed seat hinge hardware
•  During interior restoration or seat refurbishment

Knob For Seat Runner Adjustment, Black.
The OE Match Knob for Seat Runner Adjustment, Black is a replacement seat adjustment knob for early classic Porsche 911 2.0–2.4 models from 1963 to 1973.

Fits:

• Porsche 911 1965-1968 2.0L / 912 SWB (F)
• Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)  

Diagram Ref No 24

The knob forms part of the manual seat runner adjustment mechanism and provides the hand-operated contact point used when releasing or adjusting the seat position. Finished in black, it is designed to replace an original knob that has become worn, cracked, damaged or missing.

As a small but frequently handled interior component, replacing a deteriorated seat runner knob helps restore both the function and appearance of the seat adjustment system.

What This Product Does:
The seat runner mechanism allows the seat to slide forwards and backwards so the driver or passenger can achieve a suitable seating position.

The adjustment knob provides a comfortable and secure surface for operating the seat runner release mechanism. When used, it helps disengage the runner locking system so the seat can be moved along its rails before locking securely into the chosen position.

Its functions include:

• Providing a convenient hand grip for seat adjustment
• Helping operate the seat runner release mechanism
• Allowing the seat to move forwards and backwards
• Supporting correct driving and passenger seating position
• Protecting the underlying adjustment lever or mechanism
• Restoring the original appearance of the seat hardware

Symptoms Of Wear Or Failure:
Seat adjustment knobs can deteriorate through repeated use, age and general interior wear. Common signs that replacement may be required include:

• Cracked or split knob
• Missing sections of the knob
• Loose fit on the adjustment mechanism
• Knob pulling off during use
• Worn or damaged mounting point
• Smooth or heavily worn surface making it difficult to grip
• Seat adjustment becoming awkward because the knob is missing
• Visible scratches, fading or deterioration
• Knob no longer remaining securely attached
• Exposed metal lever or adjustment mechanism

A stiff or jammed seat runner is not necessarily caused by the knob itself. The rails, locking mechanism and associated hardware should also be inspected if the seat is difficult to move.

Why Replacement Matters:

• Although small, the seat runner adjustment knob is the component the user directly handles when changing the seat position.
• A cracked, loose or missing knob can make the seat adjustment mechanism uncomfortable or difficult to operate and may leave the underlying lever exposed. Continued use of a damaged knob can also cause it to break completely or detach from the adjustment mechanism.
• Replacing the knob restores a secure gripping surface and makes routine seat positioning easier. Maintaining proper seat adjustment is important for achieving a comfortable and appropriate driving position and for allowing different drivers to correctly position themselves relative to the pedals and steering wheel.
• For classic Porsche restoration projects, a correct black replacement knob also helps restore the factory appearance of the interior and replaces a frequently worn detail.

Rallye Seat Frame and Foam Kit - 5 Point Seat Belt

Sold each

This R Seat frame and foam kit provides an untrimmed, fixed-back bucket-seat foundation for Porsche 911, 964 and 914 applications from 1965–94. Prepared for a 5-point belt arrangement, it allows a chosen upholstery specialist to complete the covering in materials and details suited to the vehicle. 

Fits

• Porsche 911 1965-1968 2.0L / 912 SWB (F)
• Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
• Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
• Porsche 911 1978-1983 3.0L / SC
• Porsche 911 1984-1986 3.2L
• Porsche 911 1987-1989 3.2L G50
• Porsche 911 1975-1977 3.0L Turbo (930)

• Porsche 964 (911) C2 1989-93
• Porsche 964 (911) C4 1989-93
• Porsche 914 (1970-1976)

What This Product Does

The seat-shell concept separates the supporting structure and shaped padding from the final upholstery. The kit supplies the principal components needed to establish the seat profile, while the covering material, colour, stitching and finishing work can be completed locally. This approach makes it possible to coordinate the finished seat with a restored, period-style or individually specified interior.

The R Seat shape is based on the supportive seats associated with early rally and racing cars. Its fixed bucket form creates defined back, side and cushion support while retaining an appearance appropriate for a classic Porsche cabin. Duralastic suspension belts provide a flexible base beneath the cushion rather than relying on foam alone.

Functions

• Forms the structural foundation for a fully upholstered R Seat
• Uses shaped foam to establish the backrest, side and cushion profile
• Supports the seat cushion through flexible Duralastic suspension belts
• Provides dedicated openings for a 5-point belt arrangement
• Allows the final upholstery specification to be selected separately
• Creates a fixed seating position determined by the mounting installation

Technical Details

• Kit includes the seat frame, Duralastic belt set, side and backrest foams, cushion foam and 5-point belt rosette set
• Coated steel tube frame construction
• Fire-resistant foam padding
• Approximately 385 mm side-to-side mounting distance
• Fixed, non-adjustable seat structure
• Final seat height and backrest angle are established through the mounting arrangement

Symptoms of Fault

• Seat foam has collapsed, split or become uneven
• The existing seat no longer provides consistent back or side support
• Suspension components have stretched and allow the cushion to sag
• The frame has corrosion, distortion or unwanted movement
• Damaged upholstery and padding require a complete seat rebuild
• The current seat is unsuitable for the planned 5-point belt layout

Why Replacement Matters

Renewing the frame, suspension and padding together gives the upholsterer a sound foundation for the finished seat. It avoids placing new trim over deteriorated foam or tired supporting components and enables the seat position to be set for the vehicle and driver during installation. All belt anchorages and seat mountings should be installed using suitable hardware and checked by a competent specialist.

FAQs

• Is upholstery supplied? No. The frame, suspension and foam components are provided for finishing by an upholstery specialist.
• Can the backrest be adjusted? No. This is a fixed seat structure, so its installed height and angle depend on the selected mounting arrangement.
• Is this version prepared for 5-point belts? Yes. It has the relevant belt openings and includes the corresponding rosette set.
• Can it be fitted to a Porsche 914? The supplied application includes the Porsche 914 when used with an appropriate slider or tilting bracket.

• Porsche 964 (911) C2 1989-93
• Porsche 964 (911) C4 1989-93
• Porsche 914 (1970-1976)

What This Product Does

The seat shell kit concept separates the seat’s supporting structure, suspension and shaped padding from its final upholstery. The essential underlying components are supplied as a kit, allowing a professional automotive trimmer to finish the seat in leather, vinyl, fabric or another suitable material. Colour, stitching, piping and other upholstery details can therefore be selected to complement the vehicle’s existing cabin or restoration specification.

The R Seat design is based on the supportive driver and co-driver seats associated with early rally and competition cars. Its shaped, fixed-back form provides defined support around the backrest, sides and cushion while retaining a period-style appearance appropriate for a classic Porsche interior. Duralastic suspension belts sit beneath the cushion to provide flexible support rather than relying on the foam alone.

Functions

• Provides the structural shell for a complete upholstered R Seat
• Uses shaped foam sections to establish the seat profile
• Supports the cushion with flexible Duralastic suspension belts
• Allows upholstery materials, colours and stitching to be specified separately
• Creates a fixed seating position determined by the chosen mounting installation
• Provides a period-style seat form for classic Porsche interior restoration

Technical Details

• Kit includes the seat shell, Duralastic suspension belts, side and backrest foam, seat cushion and headrest
• Fibreglass seat shell construction
• Fixed-back bucket-seat design
• Untrimmed components ready for professional upholstery
• Version specified for use with 3-point seat belts
• Mounting brackets, runners and upholstery should be confirmed separately for the installation

Symptoms of Fault

• Original seat foam has collapsed, split or lost its shape
• The seat cushion sags or provides uneven support
• The existing frame or shell is corroded, distorted or damaged
• Backrest and side support have deteriorated through age and use
• Worn upholstery reveals degraded foam or supporting components
• A complete foundation is required for a seat restoration project

Why Replacement Matters

Replacing the supporting shell, suspension and foam together gives the upholsterer a consistent foundation for the finished seat. This avoids fitting new trim over deteriorated padding or tired suspension parts and allows the upholstery specification to be coordinated with the rest of the interior. Seat brackets, runners and belt anchorages are safety-critical; installation should use appropriate hardware and be checked by a suitably experienced specialist.

FAQs

• Is the upholstery included? No. The kit is supplied untrimmed so the covering material and finishing details can be selected separately.
• What is included in the shell kit? It includes the seat shell, Duralastic suspension belts, shaped side and backrest foam, seat cushion and headrest.
• Can the backrest angle be adjusted? No. This is a fixed-back seat, so the installed height and angle are established by the selected brackets and mounting arrangement.
• Is this the 3-point seat-belt version? Yes. This kit is specified for a 3-point belt arrangement rather than a multi-point harness configuration.
• Does it fit a Porsche 914? The supplied application includes the Porsche 914, subject to the use of suitable model-specific runners or mounting brackets.
