Trusted by 10,000+ customers across the USA
Don’t risk your customer's build or your own truck on a mismatched gear ratio. Premium Used Auto Parts supplies complete, inspected carrier assemblies and rear differentials for domestic and import vehicles
Whether you need a 3.73 locking diff for a Silverado, a standard open differential, or an Independent Rear Suspension (IRS) setup, we use your VIN to verify the exact axle ratio — guaranteeing a direct bolt-in replacement with zero core charges.
A Simple 3-Step Process
Call us or submit a quote request with your vehicle’s VIN. Our drivetrain specialists pull the factory build sheet to verify your exact axle code (e.g., 3.73, 4.10, G80). This guarantees you get a carrier assembly that meshes perfectly with your existing drivetrain.
Before any unit leaves our facility, our technicians perform a strict visual inspection. We check the gear pattern, test the backlash for proper tolerances, and inspect the differential fluid for metal shavings to ensure the ring and pinion are in excellent condition.
We drain, securely crate, and dispatch your complete rear end or carrier assembly via freight. We deliver directly to commercial repair shops, body shops, or residential addresses with liftgate service. Best of all — no hidden core fees and no return shipping hassles.
We stock hundreds of inspected, low-mileage front and rear differentials for domestic trucks, SUVs, and major import vehicles. From heavy-duty locking diffs to standard open carriers, we have the right axle assembly for your build.
Save up to 70% on complete used differentials for high-demand vehicles like the Ford F-150, Chevrolet Silverado, and RAM trucks. Every carrier assembly is visually inspected, fluid-checked for metal shavings, gear pattern verified, and backed by our comprehensive warranty.
Avoid heavy dealership markups on complete rear axle assemblies. Get a genuine OEM replacement for up to 70% less than a brand-new unit.
We don't just pull parts and ship them. Our salvage specialists inspect the internal components to ensure you receive a differential ready for a direct bolt-in installation.
Skip the hassle of palletizing, strapping down, and shipping back your blown differential. With us, what you see is what you pay.
Don't guess your gear ratio. We use your vehicle's VIN to verify the exact axle code, ensuring your replacement differential meshes perfectly with your drivetrain.
We know a truck stuck on the lift costs you money. We prepare, crate, and dispatch your carrier assembly quickly to your commercial shop or residential address.
Install with confidence. Our industry-leading warranty offers nationwide protection, ensuring your drivetrain is covered long after the truck leaves the bay.
