Application

G-Comp rear suspension kits utilize a full floater Ford 9 Inch rear axle setup. Our floating rear axle design, using Grand national style hub and bearing assemblies is technology taken right from the NASCAR playbook – and for good reason. The Grand national hub is centered around a much larger, heavy-duty bearing that can handle the additional abuse that high-horsepower street and track cars deliver. The larger bearing surface also carries the torsional load placed on the wheel when cornering more efficiently than a traditional one-piece cast hub and axle design. In addition to a larger bearing carry the load, our aluminum Grand national hubs reduce rotating mass without sacrificing strength. The G Comp Torque Arm Rear Suspension allows you to run up to a 305/35/19 tire and a 10″ wide wheel with a maximum of 6.5″ backspacing without having to cut into the stock F-body body/wheel tubs.

Rear-axle housing includes caliper brackets that accept calipers with a 5.25″ mounting spacing, such as the Wilwood Dynalite 8351206816. Floater rear hubs accept 12.19″ x 0.81″ brake rotors with an 8 x 7.00″ bolt pattern, such as the Speedway Motors Pro-Lite 91031908. Combine this caliper and rotor combo with Wilwood Poly-D Brake Pads 8353991 for a complete rear brake setup. This brake combo is a great value for spirited street driving as well as entry-level autocross and road course competitions.
