Alliance all-makes heavy-duty differentials are remanufactured using 100% new bearings, washers and seals. We also magna-flux every ring gear
searching for hairline cracks before those components are ever qualified for use in Alliance reman differentials. We are the only remanufacturer
who conducts an end-of-line dynamometric test on every single differential- that’s why we offer an industry-leading two-year parts and labor
warranty on our differentials.
All Alliance Powertrain products are backed by a two-year/unlimited-mile warranty. When installed by your dealer, you will receive a two-year
warranty, parts + labor with the second year being covered as Parts + Labor (flat rate). If you order over the counter, you’re still covered
for the first year’s parts and labor (flat rate), with the second year of your warranty covering parts only.
