Losi Tenacity Lasernut HD Rear Gearbox Set (ETK2125)

The Losi Tenacity Lasernut HD Rear Gearbox Set is a bolt-on, all-machined alloy replacement for 1/10-scale Losi Tenacity models and Lasernut variants. Crafted from 7075 aluminum and including two 13mm input bearings, this heavy-duty gearbox delivers enhanced durability and precise gear mesh that stands up to high-powered motors.

Designed to keep drive gears engaged with the differential gear for reliable mesh and reduced wear, it features a polished, anodized finish with laser etching for a showroom-ready look and weighs about 90 grams including the bearings. This rear gearbox serves as a robust upgrade for the Tenacity DB, TT, SCT and Lasernut configurations.
