About this part
Reviews3.0 · 4 reviews
Fits the stock plastic diff for the Losi Tenacity DB Pro. Does not fit the aluminum diff housing without modification.
Nice gear but doesn't actually fit the stock Lasernut diff. You need to grind out the center a bit to make it fit which is disappointing for a gear supposedly designed specifically for this vehicle.
The 2024 gear installed perfectly and is holding up very well.
Didn’t fit initially and needed to grind for it to fit what it’s made for. Very disappointed with this brand and won’t buy it again. Lesson learnt!
Four reviews of the Exotek Tenacity/Lasernut HD Hardened Steel Spur Gear (40T) are mixed. Two reviewers report it fits the stock plastic diff on the Losi Tenacity DB Pro, while the two 1/5 reviews say it did not fit the stock Lasernut diff without grinding the center. One 5/5 reviewer, of unspecified verification, says a 2024 gear installed perfectly and is holding up well. One 5/5 verified reviewer notes it does not fit the aluminum diff housing without modification. Fit is the main point of disagreement and appears tied to the diff housing type. Reviewers do not mention durability problems beyond the one positive report. Sample size is small.
