Aluminum Steering Rack Bushings, 10/1984-04, center drilled, 12 mm inside diameter. Improve your Mustang's turn-in response by installing Maximum Motorsports steering rack bushings! They Increase the effect of Ackerman steering geometry by moving the steering rack rearward in the chassis and eliminate the steering rack movement allowed by rubber and urethane bushings. These precision-made bushings are CNC machined from heat-treated 6061 aluminum. Maximum Motorsports' research on bumpsteer proved that with a stock K-member, a center drilled bushing is best, whatever the ride height. When large changes in geometry have been made, as with the MM K-member, the correct use of offset steering rack bushings will relocate the rack to a position which makes it easier to correct the bumpsteer with the MM Adjustable Tie-Rod Ends. We don't recommend offset rack bushings for stock K-Members... Offset steering rack bushings move the rack far too much on stock K-Members, and make an acceptible situation far worse than if you had done nothing at all.
