70-81 ExtReme Torque Arm Suspension
The Speedtech Performance ExtReme Torque Arm rear suspension for ’70-’74 Camaros, Firebirds and Trans AM’s is the same package as our already street and track proven Torque Arm suspension but includes the addition of upgraded custom valved coilover shocks so you can maximize your track day performance even more.
Our Torque arm kits drastically improve performance handling and every day drive quality of your leaf spring car without the bind and other problems that come with other types of suspensions. Unique in it’s design, this package will virtually eliminate the inherent change in geometry and possible traction issues commonly associated with leaf springs and 4 links.
