Trailing Arm bushings stabilize the movement of the arms to ensure the correct geometry is maintained in all situations. Worn or rubber bushes in these locations lead to dynamic changes in wheel alignment that effect the handling of a vehicle as well as the tire life. SuperPro Bushings solve this issue and are the perfect repair or repair upgrade solution. Please Note : 1 x SPF2461K includes two bushing assemblies as shown in the photos - to replace the forward and rearward bushings in BOTH lower trailing arms, 2 kits are required
