Upgrade your RZR 800 with a complete stroker engine rebuild solution designed for riders who demand more power, stronger torque, and proven reliability. The Kalama RZR 800 Stroker Engine Rebuild Kit delivers real performance gains—not just on paper, but validated through real testing.

Tested In-House. Proven on the Dyno.

Unlike most aftermarket suppliers, Kalama invests in in-house dynamometer testing, a high-cost engineering process that allows us to validate power output, torque delivery, and durability before any product is released. This commitment ensures every component performs as a complete system—not just individual parts.

Built for Power and Durability

This kit features forged 82mm high-compression pistons paired with premium RIK piston rings for superior sealing and long service life. The stroker crankshaft and 82mm big bore configuration increase engine displacement, delivering stronger low-end torque and noticeable power gains across the RPM range—exactly where off-road riders need it most.

A Complete Performance Solution

Engineered with precision manufacturing, premium materials, and ease of installation in mind, this stroker engine rebuild kit offers a balanced upgrade for enthusiasts, professional builders, and performance-focused markets worldwide. As Kalama’s first complete engine kit, it reflects our commitment to delivering total engine solutions backed by real testing—not assumptions.
