Description
Maximize your engine’s performance and longevity by ensuring optimal cylinder sealing with this 4.375″ bore piston ring set featuring a +.005″ oversize fit. This precision-engineered ring set addresses common issues like compression loss and oil consumption, delivering tighter sealing to enhance power output and reduce harmful emissions.
The set includes three rings with thicknesses of 1/16″, 1/16″, and 3/16″, each crafted to maintain proper tension under standard operating conditions. This configuration balances oil control and compression sealing, minimizing wear and maintaining engine efficiency over time.
Manufactured by Je Pistons, a trusted name in engine components, these piston rings are designed specifically for engines requiring a slightly oversized bore of 4.375″ plus an additional .005″. This precise sizing compensates for cylinder wear or machining, ensuring a snug and reliable fit that prevents gas leakage and oil intrusion.
- Oversized Bore Compatibility: The +.005″ bore size accommodates cylinder re-machining, restoring optimal ring-to-cylinder contact and reducing blow-by.
- Standard Tension Design: Provides consistent sealing pressure without excessive friction, preserving engine integrity and performance.
- Ring Thickness Distribution: The 1/16″, 1/16″, and 3/16″ rings are optimized for combined compression and oil control, enhancing durability and reducing oil consumption.
- Dimensions and Weight: Measuring 27.90 cm in length, 5.10 cm in width, and 14.00 cm in height, with a weight of 1.25 kg, this set fits precisely within designated engine assemblies without added bulk.
These piston rings are ideal for engine rebuilds or performance upgrades where precise fit and reliable sealing are critical. Their robust design and exact specifications ensure consistent engine operation, helping maintain power and fuel efficiency while limiting emissions.
Invest in this Je Pistons 4.375″ bore + .005″ rings set to restore your engine’s sealing performance with parts engineered for durability and precision. Experience enhanced compression and reduced oil consumption that directly contribute to improved engine reliability and lifespan.
