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.

Already own an original 555-4105 Steeda upper 3rd link and want to take it to the next level? Purchase one of our competition upgrade kits.

The full competition version part number 555-4107 includes a competition proven chrome moly alloy rod end to eliminate all wheel hop and axle wind up. This version with a solid rod end will increase NVH in street use and is recommended for competition use only.

The dual purpose street/competition version uses our exclusive 3 piece bushing package on the axle end and is recommended for street use since it wont increase NVH levels in the vehicle.

Both competition upgrades include a new heavy duty chassis mount made from stout 1/4" thick steel for twice the thickness of the original factory piece. It also gives you 2 mounting locations for increased adjustment to provide even better traction and handling.

Steeda Stepped Spacers: 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.

Note: Our 555-4107 and 4108 upgrades do not require these spacers with their all new chassis mounts. All Steeda 555-4105 Upper Third Links produced on or after February 2007 include the Stepped Spacers.
