Includes four custom-machined polyurethane bushings with steel sleeves and special silicone grease. This kit replaces the soft, weak rubber bushings (108912) that connect the front sway bar to the lower control arms. Benefits include more effective action from front sway bar, better performance under hard braking and less deflection of the front suspension during cornering and braking. Also helps to maintain correct front wheel toe-in and caster. Ideal when used in conjunction with K1002DP polyurethane front sway bar mounting kit (see K1006DP to buy both together and save $$).
