Our Toyota Supra, Soarer, and Chaser R154 Transmission Gearsets are globally recognized Motorsport parts, utilized in vehicles worldwide for various applications including drift, drag, circuit, and street racing.
Factory transmission gearsets have been known to fail at around 400BHP.
In contrast, our kits are capable of withstanding over 800BHP. Some of our customers achieve 9-second quarter-mile times with a 1.43 60-foot start in drag racing, demonstrating the high horsepower and grip of our gearsets.
Speedtek Auto Racing Transmission Gears are crafted from high-quality forged billet materials and machined to precise tolerances.
SPLINE TYPE: STANDARD (No clutch change required for easy installation)
GEAR RATIOS:
When ordering, please specify your gearbox version, as there is a distinction between the R154 Remote Shifted Transmission and the Non-Remote (Standard Shifter on top of the transmission housing) versions.
For those with the REMOTE Shift Transmission commonly found in JZX100 and JZX110 Toyota Chasers and Mark IIs, the 1st-2nd Gear Shift Sleeve and Synchro kit are required for this kit to function, hence the additional cost for a remote shift transmission kit.
