Buick Rainier Front Differential 7.25-Inch 2002-2007

We're proud to offer this remanufactured 7.25-inch front differential for the 2002-2007 Buick Rainier. This unit can be configured with a 3.73 or 3.42 gear ratio to match your vehicle's original spec. Rebuilt to spec in-house, this unit ships with our 3-Year Warranty — axles, hubs, and backing plates are included. Bolt it straight into your drivetrain, top off the fluids, and you're back on the road. We're based in Pueblo, Colorado, with over 34 years of experience rebuilding and remanufacturing Buick drivetrain components. A lot of online sellers just drop-ship; we actually rebuild and inspect every unit ourselves. Call us if you need a different gear ratio; we also build custom differentials from scratch. Core charge policy: no charge upfront as long as your old core is scheduled for pickup within 30 days of the purchase date. Waiving the core charge means authorizing us to bill your credit card for that amount if the core hasn't been returned by then, and skipping the return (or payment) voids the warranty. Return shipping is free, courtesy of Nationwide Differential. Cores must be in acceptable condition (free of cracked housings, bent tubes, etc.), so call 719-460-7267 with any questions.
