These cups are designed to keep you in the race longer. With additional slots to lengthen the amount of time needed before service.

This is the better designed FLM 4EVER original kit, not the recent failed 2.0 enclosed version which causes pins binding and premature failures! We made the decision to discontinue the “2.0 4EVER” cup set after multiple failures and have chosen to stock the original with a better performance record. This is compatible with all generations of Losi 5IVE including 5T 1.0, 2.0, 3.0 and TLR 5B

Warranty is against breakage and premature wear. Will they last “forever”? No. All warranty claims for Fast Lane Machine products are handled by Fast Lane directly:[email protected]

Note: the FLM centre diff cups are not compatible with the SRC Upgrade center driveshafts. They are a direct fit with the original Losi center driveshafts and dog bones.
