New from TCI Engineering – the 1964-70 Mustang torque arm rear suspension kit for mini-tubbed applications. This kit will help out applications that use wider tires. See more details below.

Official Release:

TCI Engineering’s popular Torque Arm rear suspension kit for ’64-’70 Mustangs has been reimagined to work with mini-tubbed vehicles. Our proven Torque Arm rear suspension has been redesigned to work with up to a 315 wide tire(‘64-‘68) & 335 wide tire(’69-’70). Using many of the existing Torque Arm kit components we were able to keep with the proven suspension geometry and produce a new kit that performs even better due to the extra contact patch from wider tires. The mounting points for the lower links bars have been moved inboard of the frame rails, providing more space for a wider wheel and tire package. We’ve added frame reinforcement brackets and an adjustable chassis tie bar to stiffen the whole assembly as well. If the ultimate handling and maximum tire width is what you desire for your early Mustang, this kit offers everything you need.


  • Works with up to a 295 wide tire on ’64-’66 Mustangs
  • Works with up to a 335 wide tire on ’67-’70 Mustangs
  • Frame reinforcement brackets and adjustable chassis tie bar stiffen entire assembly
