SWEET!!! I’ve used different differential fluids with different viscosities for getting the axles to drive straight and even, yet still corner well. Oddly enough, this solid-steel axle ROCKS for straight-line acceleration, the cornering isn’t damaged that much, and coming out of a corner is freaking awesome. I have high regards for this axle, and it will be my go-to solid-steel axle in the future. Thank you for your time on this matter. Casey.

Perfect fit in my slash differential. This is for my speed run car so it should hold up just fine.

Jeremy PrestonVerified ownerMay 19, 2024on ST Racing Concepts Steel Solid Axle for Traxxas Slash/4Tec 2.0

Used this in the rear diff during my drift build. Allows for excellent power delivery to both tires. Install was super simple. Ran though about 10 packs so far and no issues.
