About this part

Exotek Tenacity/Lasernut HD Aluminum Differential Case. This is an optional accessory intended for the Losi Tenacity and Lasernut platforms. Constructed from high quality, hard anodized aluminum this differential case adds additional strength to the drivetrain making the differential capable of handling incredible amounts of power and abuse. This two piece differential case is easier to seal and maintain compared to other 3 piece designs, helping to eliminate leaks over the long run. Designed to work on the front, rear or center differential this upgraded case is an excellent option to increase durability and lower maintenance on your next build.

NOTE: Fully assembled differential in photos is for illustration purposes only and additional parts will need to be purchased to complete the differential. See "Includes" for a list of items that are included with this kit.

Jarrett MaltryVerified ownerMay 27, 2024on Exotek Tenacity/Lasernut Aluminum HD Differential Case

The design that holds the cross pins has so little surface area that it’s actually weaker than stock housing with the square inserts that distribute pressure better. Ran one pack through with 50k diff fluid on my losi DBpro and it took chunks out of the inside of the diff casing. May not have happened with thinner fluid but still…. For $40 and “7075” aluminum, I thought it would hold up for at least a little while
