For club racers and weekend builders looking for a reliable rear belt, the RACEOPT 3m-513-(PU) Optional Rear Belt RO-S3M-513 delivers a practical replacement. Its polyurethane build is chosen for longevity under repeated use.
This belt suits several common RC car kits and is known to fit models from Xray and RGT2 without requiring major modifications, making it a good replacement choice across hobby projects.
Polyurethane brings stronger wear resistance than conventional rubber, helping the belt hold tension and reducing the frequency of belt changes during regular running.
