Revive spirited, efficient performance in your 2007–2015 Scion tC or xB 2.4L 4-cylinder with this targeted Re-Ring kit from LowPricedAutoParts. Engineered for the DOHC 16-valve naturally aspirated 2AZ-FE engines in these fun-to-drive coupes and hatchbacks, this kit addresses common piston ring wear that leads to increased oil consumption, compression loss, and reduced responsiveness—providing a cost-effective refresh without a full engine overhaul. The premium piston rings deliver enhanced sealing and extended service life compared to standard options, making them an ideal upgrade for sporty daily drivers, commuters, or enthusiasts who appreciate Scion's unique style and handling. This kit includes quality rod bearings, main bearings, a thrust washer, head gasket set, and lower gasket set to cover the ring replacement and complete sealing needs. All components are supplied in standard size for stock bores and journals—no machining required if your engine measurements remain within factory specifications. This kit is offered with standard size rings and bearings for engines that do not require machining – ideal for low-to-moderate mileage 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. Expansion plugs are not included—source separately if required for your build. Verify your exact year, engine code, and application 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 Scion tC or xB 2.4L running smooth and fun again!
