Product Information

Front upper wishbone.
The Porsche Genuine OE Front Upper Wishbone / Control Arm (Part No. PAD407021A) is an original factory front suspension upper control arm designed for the Porsche Taycan (9J1) platform. Also commonly referred to as a wishbone or upper suspension arm, this component forms a critical part of the Taycan’s advanced front suspension system. It is supplied complete with integrated ball joint and suspension bushes for precise OEM fitment and performance
Sold individually, fits both left and right front suspension positions

Fits:
Porsche 9J1.1 Taycan 2020 - 2024

Diagram ref no 13

The upper control arm guides and stabilises wheel movement while allowing controlled suspension articulation during steering, braking, and cornering.

It connects the steering knuckle to the chassis/subframe and helps maintain:
• Accurate wheel alignment
• Steering precision
•  Suspension geometry
•  High-speed stability

The integrated bushes help absorb vibration and road harshness, while the ball joint allows smooth suspension and steering movement. This is especially important on the high-performance and heavy-load suspension system used on the electric Porsche Taycan.

Functions & Technical Role
• Suspension geometry control: Maintains correct wheel movement and alignment
• Integrated ball joint: Allows smooth steering and suspension articulation
• Vibration damping: Bushes reduce noise and harshness transferred to the chassis
• Handling stability: Supports precise steering response and road holding
• OEM engineering: Manufactured to Porsche factory tolerances for exact fitment and durability

Fitment / Position on car
• Fitting position: Front axle upper
• Side: Left = Right
• System: Front suspension and steering geometry control

The upper control arm plays a major role in steering accuracy, suspension stability, and tyre wear control. Worn bushes or ball joints can negatively affect handling, ride comfort, and wheel alignment.

When to replace
•   Knocking or clunking from the front suspension
•   Excessive play in the ball joint or bushes
•   Uneven tyre wear or alignment problems
•   Steering instability or vague handling
•   During suspension rebuild or accident repair

Set of 2 x Adjustable lower control arms - 1 pair, required per axle

Elephant Racing adjustable lower control arms provide the camber, caster and precision you need. Length adjustable similar to the factory GT3 control arms, but without the need for shims.

Quick and Easy Adjustments – No need to keep a stock of shims on hand, length is easily adjusted by rotating the center hex head. Rotate clockwise to expand or counter-clockwise to contract the arm length.Adjustments can be made within minutes. No shims to mess with. Perfect setup to make quick changes for the track.

Widen Track – Use in combination with our camber plates on the front, or our adjustable length arms upper control arms on the rear to widen the track. This allows you to achieve a wider track without altering the scrub radius as happens when using wheel spacers.

Heim Joint – Our spherical bearings eliminate the deflection associated with rubber bushings. These bearings maintain stable suspension alignment, and improve feedback.

Fully Weather Sealed – Proper boots at both the ball joint and heim joint ends to keep water and contaminants out for extended life. These arms are suitable for extended road and track use.

Camber Adjustment – Extended range of adjustment lets you achieve aggressive camber. Or you can dial it back to get a factory street alignment on lowered cars.

Caster Adjustment – Our Caster Adjuster allows you to tune this important setting that the factory left out. A must-have for cars that have extended lower control arms to correct for un-intended caster change that is caused by the extended arms. Rotate the center puck and bolt down to secure the setting.

The arms are fully rebuildable with replaceable heim and ball joints.

On 996, 997, & 991 Cars:
Center puck can be also used as a wheelbase adjuster on the rear to draw the wheels back to improve weight distribution. It is a great tuning aid for adjusting out understeer

Litronic Bracket – This bracket is required for cars that are originally equipped with the litronic headlights. This adapter bracket attaches to the headlight angle sensor.

Caster Tuning
Our Caster Adjuster allows you to tune this important setting that the factory left out. A must-have for cars that have extended lower control arms (GT3 control arms or eccentric monoballs) to correct for un-intended caster change that is caused by the extended arms.

Caster is also a great tuning aid for adjusting out understeer. Our Caster Adjusters let you tune the caster you need.

Two eccentric mounting points increase range of adjustment by up to 25mm. Choose from the inner bore for minor caster adjustments or the outer bore for extreme adjustments.

Rear Weight Bias
For the rear suspension, our Caster Adjuster can reduce rear overhang and rear weight bias. Cars with aggressive rear camber actually draw the wheels forward, increasing rear weight bias. Use our Caster Adjuster to compensate and even over-compensate for less rear weight bias than stock

Maintain Proper Alignment
Our Caster Adjuster is solid aluminum to hold alignment settings precisely. Stock rubber bushings compress under load, allowing alignment to wander and making the car less predictable. Our solid design eliminates compression, improves precision and maintains geometry true.

Functional Design Built To Last
Available for factory type lower control arms (wishbones) front and rear, including stock type arms and GT3 arms
