Restore peak compression and sealing on Kawasaki KVF 360 quads built from 2003 through 2012 with this OS 1.00 oversize piston ring kit. Specifically sized for the KVF 360 family, this kit helps reclaim lost power, reduces oil burn, and sharpens throttle response for trail riding or farm work. When rings wear and end gaps drift, you’ll notice slower starts, weaker hill climbs, and higher oil consumption—this OS 1.00 kit is designed to bring those symptoms back in line and keep the engine breathing cleanly under load.

This aftermarket replacement is built to address the wear and end-gap drift that accumulates in KVF 360 engines after years in gritty conditions. By restoring proper ring seating and reducing blow-by, it helps maintain compression and oil control, so you can rely on steady power when you’re working hard or pushing through rough terrain. Engineered for durability in dirt, heat, and demanding use, it’s a dependable choice for riders who demand performance without sacrificing reliability.

Why Choose This Aftermarket Replacement?

• Direct-Fit Compatibility: Precisely matched to the KVF 360 2003-2012 engine family for straightforward installation.
• OEM Cross-Reference: Uses Kawasaki OEM reference 13025-0002 as the compatibility baseline while delivering an aftermarket solution.
• Premium Materials & Tolerances: Engineered to meet or exceed OEM specifications to maintain proper end gaps and seating in the KVF 360 cylinder.
• Performance Restoration: Designed to restore compression, reduce blow-by, and improve engine response after wear.
• Reliability in Tough Conditions: Built to endure dirt, heat, and heavy workloads common on trails and farms.
• Quality Control: Produced as an aftermarket replacement with consistent fit and finish for repeatable service life.

Installation Notes:

• Verify OS size: Confirm OS 1.00 oversize matches your cylinder bore before installation.
• Measure bore and ring gaps: Use a bore gauge and feeler gauges to ensure end gaps fall within acceptable KVF 360 specifications.
• Premoisten rings: Lightly lubricate all rings with clean engine oil before installation.
• Clean surfaces: Thoroughly clean the cylinder, ring grooves, and oil passages to avoid dirt-induced seating issues.
• Ring orientation and seating: Install rings with the correct side facing outward and stagger end gaps to avoid alignment with the same position as the previous ring gap.
• Ring compressor use: Use an appropriate ring compressor to evenly seat rings into the bore without nicking edges.

Why Upgrade?

Running a worn piston ring set allows blow-by and compression loss to creep in, which quietly robs power and increases oil consumption. Upgrading to the OS 1.00 oversize kit restores seating and sealing, delivering reliable throttle response and consistent performance when you’re carving through trails or hauling loads on the farm.
