A Thank You to Our Valued Customers.

If you're tackling a top-end rebuild on your Honda TRX 450 Foreman 4x4, this piston ring kit is the precise aftermarket solution designed for the 1998 to 2004 models, delivering restored compression and superior sealing to get your ATV back to peak performance on rugged trails or demanding farm duties. Engineered as an oversize 0.50 mm option, it directly addresses the wear that leads to poor ring seating and oil blow-by, ensuring your 433cc engine runs with the efficiency and power it had when new. By swapping out worn rings, you'll experience smoother operation, reduced fuel consumption, and the kind of reliable response that keeps you moving through tough terrain without hesitation.
