SUMO GEAR LC80 UNDERDRIVE


This Underdrive kit was designed for the customer that would benefit from re-gearing their truck to bring the engine performance back up after increasing their tire size. Or a customer that would like to have more performance at lower rpm’s.

By exchanging just the input gear and hi-speed gear this kit lowers the high range ratio from 1.0:1 to 1.097:1 which effectively turns a 4.11:1 ring and pinion ratio into a 4.51:1 making it a great low cost alternative to re-gearing your differentials.
