Manufacturer specifications
Roca Hard Rubber bushings take the place of the OEM Soft Rubber bushing that attaches the trailing arm to the chassis. This offers a more stable and direct feeling during cornering and at higher speeds. The Hard Rubber bushing does not require maintenance or lubrication and performs with little or no noise.
Professional installation is required as you will need to use a press to remove the old bushing and install the new one. A slight vibration may be felt due to being able to feel the road more directly.
- Material: Steel Alloy / Rubber
- Color: Black
- Placement: Rear
- Reduces vibration and increase steering response
- Formulated Out Of High Quality Rubber Raw Material Formula and the bushing is using “NR+BR” Rubber Raw Material
- Replaces Your Worn Out Bushing Without Replacing Your Whole Suspension Arm
- These are aftermarket replacement parts and are a great alternative to buying the expensive dealer parts. They fit and work exactly like the OE
- Regular greasing not required
