Positioned inside the drop link bush, the spacer tube helps maintain the correct distance and alignment of the mounting assembly when the fixing hardware is tightened. It prevents the rubber bush from being excessively compressed while providing a stable internal support for the anti-roll bar connection.

This small but important suspension component is ideal for replacing an original spacer that has become corroded, worn, distorted or lost during suspension refurbishment.

What This Product Does:
The front stabilizer bar, also known as the anti-roll bar, helps control body roll by transferring suspension forces between the left and right sides of the vehicle.

The drop links connect the stabilizer bar to the suspension, while the spacer tube sits within the drop link bushing and helps the mounting assembly operate correctly.

Its functions include:

• Supporting the front stabilizer bar drop link bush
• Maintaining the correct spacing within the mounting assembly
• Preventing excessive compression of the rubber bushing
• Helping keep the drop link correctly aligned
• Providing a solid surface for the mounting hardware to tighten against
• Helping the bush articulate correctly as the suspension moves
• Reducing unwanted movement within the anti-roll bar connection
• Supporting consistent and predictable suspension behaviour

Four spacer tubes are typically required per vehicle, with two used at each drop link.

Symptoms Of Wear Or Failure:
Spacer tubes are subjected to repeated suspension loads, vibration, moisture and road contamination. Over time, the original metal components can corrode or become damaged.

Possible signs that the spacer tube or associated drop link assembly requires attention include:

• Visible rust or heavy corrosion
• Pitting or loss of metal around the spacer
• Bent, crushed or distorted spacer tube
• Excessive play in the front anti-roll bar drop link
• Bushings appearing excessively compressed or deformed
• Loose stabilizer bar mounting hardware
• Knocking or clunking noises from the front suspension
• Rattling when driving over uneven road surfaces
• Increased or inconsistent body roll
• Less precise handling during cornering
• Uneven movement of the drop link assembly
• Damage found during anti-roll bar bush replacement or suspension restoration

Because several components work together in the drop link assembly, the rubber bushes, bolts, washers and drop links should also be inspected whenever the spacer tubes are replaced.

Why Replacement Matters:

• The spacer tube helps establish the correct clamping distance within the drop link bushing assembly. If it becomes badly corroded, crushed or distorted, the bush may no longer be held at the correct compression.
• Excessive bushing compression can restrict normal movement and accelerate rubber deterioration, while insufficient support can introduce unwanted clearance and movement into the anti-roll bar connection.
• Wear within the drop link assembly can lead to knocking noises and reduce the effectiveness of the stabilizer bar, which may contribute to increased body roll and less predictable handling.
• Replacing damaged spacer tubes helps restore the correct mounting geometry, supports proper bushing operation and ensures that the anti-roll bar can transfer suspension forces effectively.
• For classic Porsche suspension restoration, replacing corroded spacer tubes together with ageing drop link bushes is also a sensible way to restore the complete mounting assembly rather than reusing deteriorated original hardware.
