LowPricedAutoParts Engine Re-Ring Kit for 1968-1978 Chevy GMC Oldsmobile Pontiac Buick 230 250 Inline-6 - Standard Size

Revive your 1968–1978 Chevrolet, GMC, Oldsmobile, Pontiac, or Buick classic with this targeted Re-Ring kit from LowPricedAutoParts. Built for the dependable 230 | 250 inline-6 OHV engines (3.8L | 4.1L) in models like the Bel Air, Blazer, C10/C20/C30 trucks, Camaro, Chevelle, El Camino, Impala, Nova, Cutlass, Omega, Firebird, LeMans, Ventura, Apollo, Skylark, and numerous GMC C/K trucks, this kit addresses worn piston rings that lead to oil consumption, compression loss, and reduced power—delivering an affordable refresh without a full engine teardown. The piston rings provide solid sealing performance suited to vintage street use, daily drivers, or restored vehicles. This kit includes quality rod bearings, main bearings, and a full gasket set to support the ring job and essential sealing needs. All components are supplied in standard size for stock bores and journals—no machining required if your engine's measurements align with original factory specs. This kit is offered with standard size rings and bearings for engines that do not require machining – ideal for low-to-moderate mileage or well-maintained vintage rebuilds where bores and journals remain in spec. If oversized rings or undersized bearings are needed due to wear or prior machining, simply reach out with your measured dimensions; we'll confirm availability and get you the exact match to complete your project right. Always verify clearances during assembly (e.g., piston-to-wall typically 0.002–0.004" and bearing specs per manufacturer recommendations) for optimal performance and longevity. This kit excludes engines with integral head design—confirm your engine configuration matches before ordering. Verify your exact year, engine code, and head type before ordering. LowPricedAutoParts is committed to providing the right parts with reliable customer support—message us your measurements or any fitment questions for fast, expert assistance. Get your classic inline-6 running smooth and strong again!
