TKX Five Speed Single Overdrive Conversion up to 750hp
For higher torque applications or you’re a ‘spirited driver,’ the TKX series five-speed is the latest offering from Tremec
This revolutionary 5-speed has replaced the TKO 500 / 600
check out these stats.
Rated for 600lb/ft of torque, will support shifting up to 8000rpm thanks to triple cone hybrid sintered synchronizers that the Tremec T56 Magnums have to make your driving experience the best.
The new end loading design makes for a stronger case with a new sleeker profile, eliminating top covers, that would have restricted room in the tunnel.
From the still photos below, you can see the clearance you can expect with a stock cross-member & mount.
