This bushing kit replaces the factory rubber bushings in your 3000GT and Stealth front sub frame set with polyurethane bushings. It comes with new metal sleeves and washers. Installing this kit will firm up the front suspension and give you a great base to start from. Also great to install if you are powder coating all of your suspension items! The kit includes bushings and hardware to replace everything on the front K member and the front cross bar (that the front engine mount bolts to).
