Spherical rod ends allow full articulation of rear axel.
I own an '06 GT Convertible with bolt-on mods, which may add 20 to 30 additional HP over stock. However, the new 4.10 differential creates a whole lot more toque than stock, and caused the OEM LCAs to twist and distort, allowing the familiar wheel hop. The OEM arms have huge rubber bushings cushioning the rod ends, which lets the axel torque to twist and compress them, distorting the intended geometry of the link. Improved LCAs were need to keep the wheels planted on the road. The installation of the Maximum Motorsports LCAs is straight forward, with easy access to the mounting bolts for removal of factory LCAs and installation of the new MM arms. Maximum Motorsports' pivoting spherical rod ends act as a ball joint within a solid housing, allowing for stable, full articulation of the live axel, and eliminates the slop of a rubber bushing mount. The MM arms move with the axel, eliminating the bushing flex effect. Consequently, the launches are smooth and predictable. Although expensive, it offers desirable qualities not found on other LCRs. The fit and finish of the arms are excellent, and the engineering of the non-binding, articulating spherical rod ends is unique. The MM LCAs work so well, I'm not sure I'll need to add a UCA.
NOTE: When removing the OEM LCA, the loose end of the axel will have a tendency to move toward the rear of the car. For ease of installation before removing the old LCA, I used a ratcheting tie-down strap to hold the position of the axel. I hooked one end of the strap into a hole located above the forward mount, underneath the chassis. I then wrapped that strap around the axel and back to the first hook, hooking the second hook onto the bottom of first hook inserted into the chassis. if the axel still moves a bit after removing the OEM arm, it can be cinched up with the ratchet to align the forward rod end with the forward mounting bracket hole, thus eliminating the need for a crowbar. Be careful not to pinch the brake line with the "axel strap."
