The LA SLEEVE Forged Piston Kit is a complete rebuild solution engineered for 4‑stroke ATV powerplants. Constructed from a high‑strength iron alloy, the kit supplies both a cylinder sleeve and a matching piston, delivering the dimensional stability required for reliable high‑rpm operation. The cast construction of the components provides consistent wall thickness and wear resistance, while the precision fit is tailored to the original equipment specifications of Honda engines.
Designed specifically for ATV applications, the kit is offered in multiple model configurations—including Honda, Yamaha, Kawasaki, and Suzuki—to match a range of displacement families. Each kit arrives as a single unit, simplifying installation and ensuring that the sleeve and piston work together as a calibrated assembly. This focused, top‑end package restores original compression ratios and supports sustained performance in demanding off‑road conditions.
