Losi Tenacity Lasernut HD Front Gearbox Set 7075 with Bearings (ETK2124)

This bolt-on front gearbox upgrade is designed for 1/10-scale Losi Tenacity and Lasernut models, delivering enhanced durability and more precise gear mesh for high-torque driving.

Machined from aluminum alloy, it features larger 13mm input bearings to better withstand motor torque and reduce bearing wear. The polished, anodized finish with laser-etched detailing provides a premium look, and at about 68 grams including the two bearings, it balances strength with manageable weight. By helping maintain solid engagement between the drive gear and the differential gear, it supports reliable performance across the Tenacity and Lasernut platforms.
