Part Number: RTS-LSDFORD-31

RTS clutch style positraction differential is a welcome alternative to expensive locker & spool differentials which are often overkill and more than the common street car requires.

RTS traction Plus systems are the latest design in differential tech upgrades. They combine the smooth operation of a limited-slip differential, with the strength of a fully machined case. These systems use carbon fiber and steel friction plate technology, delivering streetable and consistent traction. They arrive completely assembled--and because there are friction plates on machined internal gears, they are fully rebuildable. The carriers are the ideal solution for just about any light truck, sport utility, and muscle car on the road today.
