Need to reduce wheel hop and improve traction? Steeda's upper 3rd links will do the job. The Steeda adjustable upper 3rd link for S197 Mustangs gives you the ability to set your pinion angle and eliminate the torque deflection associated with the factory piece. This upper 3rd link uses our track proven three piece bushing package using soft outer bushings a hard center bushing on the axle end. This proven combination helps control axle wind up, wheel hop under acceleration, and allows for proper articulation without deflection for improved handling and cornering stability. Steeda's three piece bushing package will not increase NVH (noise, vibration, and harshness) keeping the factory's quiet, smooth operation unlike competitor's pieces. Direct replacement for the factory original bolting into the original factory location. Our 3rd link is a double adjustable design allowing you to make adjustments without removing the arm from the vehicle.555-4105 upper 3rd links come with spacers designed to fix the problem with the OEM upper chassis mount. At the attachment point for the upper link to the chassis mount Ford uses a 14mm bolt, but the opening in the mount is 16mm. This is not typically a problem with the OEM 3rd link as it uses a soft hydra mount bushing to soften this. But once an aftermarket upper is installed with a urethane bushing you get a noticeable clunk from the smaller bolt walking in the larger hole it installs into. Our spacers can be installed with all aftermarket upper arms that use the factory 14mm bolt in the factory chassis mount. The stepped spacers take up the slop and eliminate the noise from the upper 3rd links associated with the mismatched bolt/bolt hole combination. All Steeda 555-4105 Upper Third Links produced on or after February 2007 include the Stepped Spacers.
