CWR-3321 Crawler Innovations Single Stage Heavy Weight Foram 2.2/3.0" Traxxas UDR Pair

This product is a pair of heavy-weight single-stage foam inserts designed specifically for the Traxxas Unlimited Desert Racer (UDR), engineered to support high-performance and heavy RC setups. Built using dense closed-cell foam, it provides firm tire support that helps prevent sidewall collapse under hard acceleration, high speeds, and aggressive cornering. The design maintains tire shape under load, improving stability, steering response, and overall handling consistency. It is optimized for heavier rigs and basher-style driving where durability and control are more important than maximum tire flex. Sold as a matched pair, it is intended as a direct replacement foam upgrade for UDR-compatible 2.2/3.0 tire setups.
