Porsche 911 / 912 / 930 1965-89
High Density trailing arm bushings for the 911 can both eliminate clunks from failing factory units and restore proper suspension geometry in your street or track car. Made from 25% higher durometer than OEM (901.331.050.00) parts, these are the ideal replacement for either failed or simply aging stock rubber units. These bushings locate rear trailing arms better under the sustained loads often experienced on track and in the rigors of everyday driving.

Upgrade your Porsche’s rear suspension with the Heavy Duty Rear Trailing Arm Bushings Set — designed to deliver sharper handling and long-lasting durability.
These bushings secure the rear trailing arms to the chassis and are critical for maintaining correct wheel alignment and suspension geometry. Over time, original rubber bushings soften or crack, leading to excess flex, vague handling, and uneven tire wear.
The HD bushings are made from a stiffer, high-durometer rubber compound that resists deformation under load. This firmer material minimizes unwanted arm movement during acceleration, braking, and cornering — ensuring your Porsche remains planted, predictable, and precise.
Sold As A Set Of 4
x1 Set Required Per Car.

What This Product Does:
Symptoms Of Worn Or Failing Trailing Arm Bushings:
- Rear-end clunks or knocks over bumps or during acceleration / deceleration
- Loose or vague rear behavior — the rear may feel less planted or drift under load
- Uneven or accelerated rear tire wear due to shifting alignment or toe changes
- Poor handling / reduced grip in corners or when the suspension is loaded
- Vibration or harshness transmitted from rear suspension movements
- Better Handling Feedback & Precision - Less compliance means the rear responds more immediately to inputs — you feel more connection and confidence.
- Improved Geometry Under Load - During cornering or under dynamic stresses, a stiffer bushing holds alignment (camber, toe) more reliably.
- Reduced Deflection & Movement - Limits unwanted movement in the rear suspension, especially under acceleration, braking, or high lateral loads.
- Increased Durability - Heavy-duty compounds resist fatigue, heat, and aging better than soft OEM rubber, especially in performance use.
- Better Tire Wear Behavior - With more consistent alignment, your rear tires wear more evenly and predictably.
- Upgraded Feel Without Harshness - While fully rigid mounts can introduce harshness and noise, a quality heavy-duty bushing strikes a better balance: firmer control with acceptable comfort for road use.
