Serious racers finally have an engineered solution for solid spherical control arm bearings. The Pfadt kit replaces all 18 of the control arm bushings with mono-ball joints to eliminate friction and deflection. The factory busing deflection leads to unwanted toe and camber changes in both the front and rear as well as steering sluggishness. We've been running these on our race car for two seasons now and we can run less camber (because we don't have to account for the deflection), we get more consistent tire wear, and the steering is crisp and responsive. Our kit replaces all 18 bushings with beautiful 6061 T6 aluminum sleeves, anodized Pfadt orange and laser etched with our logo and part numbers. The bearings are held in place with military grade Loctite 638 and retaining clips - they are actually easier to install then polyurethane bushings. It takes about 108 individual bits to make one 18-piece kit. We do most of the work for you, so all you need to do is the install. Made and assembled in the USA, this kit is is the right solution for your control arms. This kit is the ultimate suspension upgrade for your track car and there's nothing else like it on the market. Take the final step in completing your suspension package!
