Direct Replacement
Exact-fit aftermarket replacement for OEM R302514. It uses the original mounting points and connections, so it installs with no cutting, drilling or modifications — simply remove the worn part and fit this one in its place. Each unit is matched to the original specification, so your repair goes back together exactly the way it came apart and is ready for service right out of the box.
Premium Construction
Built from not specified, selected to stand up to the heat, vibration and constant load cycles of daily commercial service. Quality materials and tight manufacturing tolerances give it a durable, dependable service life so it keeps performing mile after mile, season after season.
Heavy-Duty Application
Designed for heavy-duty truck, trailer and ready for the demands of commercial fleet operation. From long-haul over-the-road routes to stop-and-go regional work, it is built to handle the temperature swings, road vibration and continuous duty cycles that wear out lesser parts.
Premium Aftermarket Quality
A brand-new premium aftermarket part engineered to match the original's fit, form and function — never used, remanufactured or reconditioned. It is inspected before it ships and backed by PartStop's 6+ month warranty with responsive, US-based support if you ever need it.
PartStop Assurance
Premium aftermarket replacement, backed by PartStop's 6+ month warranty and hassle-free returns. All manufacturer names, part numbers and descriptions are used for cross-reference and identification only — this is an aftermarket part and is not an original-equipment (OE) product.
