HD Complete Trailing Arm Bushing Kit. Porsche 964

HD Complete Trailing Arm Bushing Kit.
Re-establish the precision and integrity of your Porsche 964’s rear suspension with this premium High-Density Complete Trailing Arm Bushing Kit.
Engineered for both street performance and track readiness, the kit includes high-density rubber bushings, aluminium insert centres, specialised press tools and installation lubricant. By upgrading from standard rubber, you’ll achieve significantly reduced arm deflection (≈ 25% stiffer than OEM), restored alignment stability, improved rear-end control and sharper handling. A complete set per car, this kit is indispensable when you’re refreshing your rear suspension or upgrading to performance-level behaviour.

What This Product Does:

• The rear trailing arms are essential suspension components that locate the rear axle/wheel assembly longitudinally and laterally under acceleration, braking and cornering. The bushings at the arms' mounts provide pivotal or semi-rigid interfaces with the chassis/subframe.
• Over time, OEM rubber bushings compress, soften, degrade or allow flex, which leads to movement in the trailing arms. That movement can cause instability, alignment changes, tyre wear, and a loss of rear-end precision.
  
• By installing this HD kit, you tighten up that mounting — the arms stay located exactly where they should under load, geometry is more consistent, compliance is reduced, and the car’s rear suspension behaves more precisely.
• In short: less “slop,” more control. The kit helps maintain proper alignment (camber, toe) under dynamic conditions, improves handling, enhances driver confidence and extends life of related components.

Symptoms & When You Might Need It:

• Clunks or knocking noises from the rear when going over bumps or accelerating — the trailing arm mount may be moving.
• Rear-end instability or “wandering” in corners — the suspension doesn’t feel crisp, the rear moves more than it used to.
• Uneven or accelerated tyre wear on the rear wheels, particularly inner/outer edge — geometry is shifting under load.
• You’ve modified your car (lowering ride height, installing stiffer springs/ARBs, bigger tyres) and the factory bushes are now too soft to maintain control.
  
• On inspection you notice visible wear/deformation: rubber bushings cracked, compressed, arms have play in their mount.
  
  

Why Replacement / Upgrade Matters:

• Ageing bushings compromise alignment, handling and safety. By upgrading you restore rear suspension behaviour to (or above) the original specification.
• The HD kit ensures the trailing arms remain properly located under load — this means your tyres stay planted, your rear geometry remains correct, and your car remains stable at speed.
• Using superior materials (denser rubber / aluminium centres) helps prevent further deflection, reduces stress on adjacent parts (arms, mounts, subframe) and improves longevity.
• Especially important for performance, track use or modified vehicles: these cars demand tighter suspension behaviour, so upgrading bushings is foundational to making the rest of the system work properly.
• Even for standard road use, replacing worn trailing arm bushes is a high-value maintenance item: better ride quality, fewer odd noises, improved resale value.
