This is an optional ST Racing Concepts CNC Machined Aluminum Shock Cap Set, and is intended for use with the Axial Wraith and Axial EXO Terra Buggy. These CNC machined aluminum upper shock caps will help to increase durability compared to the stock plastic caps, and add great looks to your ride. Combine these shock caps with the ST Racing shock bodies (SPTSTA80036), to complete the conversion and make your Axial Wraith or EXO stand out from the crowd!

These will fit the XR10 shocks just fine, but depending on your setup, the fact that they're square/flat across the entire top can cause them to bind against the shock mounting nut. I was able to put a thin 3mm nylock nut on it instead of the regular nylock and it provided ample clearance between the nut and the cap.
Axial's caps are rounded across the top surface to alleviate this problem.
Thought I'd mention it since it's not something readily visible by the photo.
But these STRC caps are first class quality. Well-machined, plenty beefy, and perfect fit for the shock bodies, just like everything STRC puts out.
