Item Description

99-04 Ford Mustang GT 8.8" 3.27 Rear End Axle Limited Slip Differential 85k 5515



Rear loaded axle assembly from a 2004 Ford Mustang GT with 85k miles. This was carefully removed from the vehicle and in good used condition. The cover has been pulled and inspected, and the ring, pinion, and spider gears all look very nice with minimal wear. When the fluid was drained it was free of any heavy metallic, metal shavings or any other debris. This will need the differential cover resealed, and new fluid installed prior to use. The axle housing has some minor scale and light rust throughout but is still in good usable condition with no bent or broken parts. The right side ABS speed sensor connector is damaged, and will need the sensor replaced. The brake calipers and rotors are included, but may need replaced and are not guaranteed to be good. The parking brake cables are attached and included and in good condition. The images are of the actual item you will receive.

This assembly has been drained of its fluids and WILL need to be resealed and refilled with the proper lubricants prior to use.

Fits 1999-2004 Ford Mustang GT with 8.8" ring gear, 3.27 gear ratio, with ABS, and limited-slip differential as a direct replacement.

Importapart is an auto recycler based in Hazelwood, Missouri. Every part we sell is a real, inspected OEM piece pulled from our own inventory — no aftermarket guesswork.

Questions on fitment or availability? Email Importapartsales@gmail.com or reach us through our contact page and we’ll get back to you within one to two business days. Hours are Mon–Fri, 9am–5pm CST.

We accept all major credit and debit cards and the other payment methods shown at checkout, processed securely through Shopify. Payment is due in full at the time of purchase, and sales tax is applied where required.

For programmed ECU/ECM/PCM orders, be sure to submit your VIN, odometer reading, and current part number at checkout so we can program the unit before it ships.

We ship to all 50 states. Most orders leave our Hazelwood, MO shop within 1–2 business days by FedEx, UPS, or USPS, and you’ll get tracking by email as soon as it’s on the way.

Heavy items like engines, transmissions, and body panels may ship freight — we note that on the listing when it applies. Alaska and Hawaii have a flat-rate surcharge calculated at checkout. We don’t ship to PO Boxes or outside the U.S.

Local pickup is available at our Hazelwood facility by appointment — call ahead to set a time.

Returns are accepted within 60 days. A 20% restocking fee applies to standard returns, but it’s waived if we sent the wrong part, it arrived damaged, or it’s verified defective. Inspect your order on arrival and contact us within 7 days in those cases — we cover return shipping.

Programmed ECU/ECM/PCM modules are returnable only if defective, damaged, or incorrect. Because each one is programmed to the VIN you provide, we can’t take them back for compatibility issues from an incorrect VIN, odometer, or part number — double-check before you order.

Approved refunds are issued to your original payment method within 10 business days.
