Torque Arm Rear Suspension
TCI Engineering’s 1970-1981 Pontiac Firebird Torque Arm Suspension assembly is engineered for Street, Autocross and Road Course Applications. The Torque Arm rear suspension was designed to eliminate the suspension bind that occurs when cornering using the stock conventional leaf spring suspension. The Torque Arm features a telescoping slider at the front of the arm that rotates as the car goes through suspension travel and articulation. This allows the cars handling to be controlled by the coil-over shocks and the rear sway bar with no suspension binding variables. The kit allows for a lowered stance, greater rear axle control and dramatically improved handling.
There are 3 height adjustments on the axle brackets in one inch increments. You also have the ability to fine tune the ride height further with the adjustable coilovers.
The installation mostly requires drilling and bolting in components. The 1970-1981 Pontiac Firebird Torque Arm Suspension kit is a bolt on application except for welding the axle brackets, panhard bracket, Torque Arm tabs and optional sway bar brackets onto the axle housing. We provide detailed instructions to properly attach the axle brackets and a fixture for the Torque Arm tabs. The optional anti-sway bar will require brackets to be welded onto the axle housing as well. The kit is available for any housing utilizing 3″ axle tubes. Complete 9” axle housings are available fully welded and ready to be bolted in.
All TCI Engineering products come with our Dual Warranty. 6 Year, 60,000 Mile Warranty on wear and tear items like bushings, coil-overs, & ball joints. Any items built in house by TCI Engineering such as link bars, control arms, spindles, crossmembers, etc come with a Lifetime Warranty.
