Ideal for Chevelle,NOTE: This is a set of bushings that must be disassembled for installation. Slide out the inner bushing, slide out the bushing, push in the outer bushing Control Arm, liberally grease the bushing (buy some Prothane grease extra, you'll need/need it - it's for urethane/steel grease done) and then install the inner (bolt-on) bushing(s), this won't give you a snug fit and a squeak-free installation. These bushings are designed to be a rotating part of your suspension, not a "spinning piece of rubber" like factory bushings. Significant improvement in road feel and cornering. HUGE power boost when using my favorite on the ramp (check your local street course!) So good it took care of the rear wheels, stabilizer bar bushings etc. Big improvement, - High quality, made in the USA! Thank you for such a great product.
