When your E-Z-GO Express S4 needs a reliable rebuild, REV6 delivers expert craftsmanship with precision upgrades. We rebuild your engine using premium components for maximum durability. Plus, every rebuild includes a 1-Year Warranty and free nationwide shipping for added peace of mind.

What the Rebuild Includes

• Core Inspection – We verify that each core meets rebuild standards before starting.
• Crankshaft & Rod Evaluation – Ensures strength and reliable operation.
• Cylinder Bore Restoration – Trued, straightened, and crosshatched for ideal sealing.
• New Pistons & Rings – Restores compression and smooth engine performance.
• Complete Gasket Kit – Ensures full sealing across engine components.
• Oil Seals – Renewed to prevent leaks and extend engine life.
• Valve Guide Seals – Improve control of oil flow and reduce wear.
• Valve & Head Service – Valves ground precisely and lash set for efficiency.

Core Requirement

We require a rebuildable core to process your order. If you don’t have one immediately, a refundable core charge applies until your core arrives. Ensuring your core is intact and functional helps avoid delays.

Why REV6 Stands Out

Our technicians hand-assemble every engine and then conduct a second inspection to confirm quality. As a result, your rebuilt S4 often outperforms standard options. For more details on shipping, warranties, or our process, visit our FAQ or Help Center.
