HRLMJ125 - Aluminum Differential Posi Locker Spool Losi LMT

This product is an aluminum differential posi locker spool designed to replace the internal spider and side gears in compatible Losi differentials. The precision‑machined spool locks both outputs together to eliminate differential action, improving traction by ensuring both wheels turn at the same rate in low‑grip or high‑power situations. Machined aluminum construction provides strength and resists wear while keeping rotating mass lower than heavier steel alternatives. Its direct‑fit design installs into the existing differential housing without modification for a simple traction upgrade.
