Product details

GU6 is the ratio option code on this GM 7.25 front carrier assembly, listed at 3.42 for 2002-2009 Chevy Trailblazer and Envoy. Ring gear diameter is 7.2 inches and the notes describe the unit as IFS; vendor SKU is RAA440-1371D. Where one platform was built in several ratios, the option code is a firmer identifier than the model year. Confirm 3.42 on the axle tag at the other end before ordering.

Every differential and axle assembly we sell is fully remanufactured to meet or exceed OEM specifications. Our remanufacturing process:
  • Deep Clean – To start the remanufacturing process, each unit is fully disassembled and cleaned.
  • Inspection – The ring and pinion, internal gears, clutches and carriers are carefully inspected. Gears are checked for proper tooth contact, and axle tubes are inspected for straightness.
  • New Components – All seals and bearings are replaced, and gears are reset for correct rolling torque for maximum efficiency and performance. Backlash is reset carefully for maximum longevity and quiet operation.
  • Validation – After reassembly, each unit is spin tested as part of a detailed checklist validation process.
Every differential and axle assembly carries a 6-month limited warranty as standard. A 7-year / 1,000,000-mile extended warranty and a core-fee waiver are available on request for qualifying remanufactured units — ask us before you order and we will confirm eligibility.

Full details: our remanufacturing process and warranty terms. As an exchange unit a refundable core charge may apply.
