Power up your 2001–2004 Ford F-150 (including Heritage) 5.4L 330 supercharged V8 with this targeted Re-Ring kit from LowPricedAutoParts. Engineered for the Triton SOHC engines (supercharged variants, from 12/05/00 production, except Power Improved), this kit addresses common piston ring wear that leads to oil consumption, compression loss, and diminished boost/torque—providing an efficient refresh to keep your Lightning or supercharged truck performing strong without a full engine overhaul. The premium piston rings deliver enhanced sealing and durability compared to standard options, making them a smart upgrade for performance trucks used in street driving, towing, or spirited acceleration. This kit includes quality rod bearings, main bearings, a head gasket set, and lower gasket set to support 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. This kit is for supercharged applications from 12/05/00 production (except Power Improved)—confirm your production date and engine setup before ordering. Verify your exact production date, VIN, 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 supercharged 5.4L Triton V8 running smooth and strong again!
