Bolt on replacement, all machined alloy rear gearbox for the 1/10 Losi Tenacity (DB, TT, SCT etc) and Lasernut series. Our heavy duty gearbox delivers extra durability and precision gear mesh and alignment- the alloy construction insures the drive shaft gear maintains 100% teeth engagement against the diff gear to eliminate the problem of worn gear teeth and poor gear mesh. Additionally, larger 13mm input bearings are included to better withstand the forces of high powered motors on the input shaft to reduce bearing failures there.
