Eliminate Deflection

This CorteX Racing S550 Mustang Front Monoball Spherical Bearing Kit allows the control arms to pivot in a smooth and accurate motion by eliminating deflection and bind found in the OEM rubber control arm bushings. As the stock suspension loads and unloads, deflection occurs causing alterations to toe and caster, resulting in an inconsistent and nervous feeling on track!  The excessively soft OE bushings show drastic, visible, deflection during hard cornering resulting in loss of performance and decreased driver confidence. Check out the video below to see what we mean! With minimal NVH increase, these bushings are essential for any dedicated track car and perfect for street cars looking to improve the suspension feel of their car.

Easy Install

Removing the factory bushings from the front and rear S550 control arms can be a difficult all-day affair if you do not have access to a press. Let the pro's handle the hassle. We offer this kit pre-installed into GT control arms to make installation an easy bolt-on affair. This service includes installation of either front or rear spherical monoball bearing kit ($80) and includes a set of factory control arms ($200 core charge.) Once you've installed your new arms, simply just send your old arms back to us and we will then credit you the $200 core. Make sure to select this option when adding our bearing kits to your cart!

Legendary CorteX Quality

The CorteX Racing Front Monoball Spherical Bearing Kit utilizes an American made high quality stainless ball and Teflon lined race so you will have years of trouble free life from the bearings. Our red anodized stainless steel ball bearing cages are American made and corrosion resistant. As with all CorteX parts, we utilize top of the line stainless steel spacers, and retaining clips.
