Warranty & Support

Every Cushman Refresher FS4 rebuild comes with a solid 1-Year Warranty. Furthermore, you can upgrade to our 2-Year No-Fault Warranty for even greater confidence. For details on shipping and core processing, visit our Help Center or review our FAQ.

Why REV6 Stands Out

We hand-assemble each engine and then conduct a second inspection to ensure precision and durability. As a result, you receive a build that consistently outperforms stock replacements. If you’d like guidance before ordering, feel free to contact us.

Core Requirement

A functional, rebuildable core is required to complete your order. If you can’t provide one upfront, we’ll apply a refundable core charge until your core arrives. Be sure your core is intact for a smooth rebuild experience.
