PLEASE READ These are an all new design developed by me, This insert has both External and Internal structures meaning there is more than the exterior that you see. This structure breaths and has a similar rebound as many stock tire foams but with sidehilling capabilities forms cannot provide, not to mention these inserts can squish under load much better than anything else on the market. This is a FRONT insert for capra axled vehicles, as this will keep the tire out to help in clearing steering knuckles, the REAR versions narrow the rear trackwidth to get through gates. If you are using any normal SCX width axle, get these FRONT AND REAR for normal track width. These are specifically for the JConcepts Megalithic tires on Carbon wheels from amazon https://amzn.to/3YNCCKc It is highly advised to store these on a vehicle supported by the axles or chassis, if you experience flat spots, just simply drive they'll roll out. These are sold in pairs (2) These lock into the groove in the inner lock ring so no sideshifting under normal conditions. These are not intended for normal 1.9 Beadlock wheels. weight range 5lbs min to 7lbs max my test truck is just over 5lbs
