    Fitment Tips
    • Rear axle: 2014+ trucks may use AAM 11.5 or 11.8 (16-bolt). Match overhaul kits and covers to your axle tag.
    • Front axle: 2011+ AAM 9.25 ZF uses different gear/kit part numbers than early designs—use ZF-specific listings.
    • Re-gearing: Always re-gear front and rear together to maintain 4WD compatibility.
    • Towing & tire size: Taller tires benefit from numerically higher ratios (e.g., 4.10–4.56) to restore driveability.

    Frequently Asked Questions

    How do I confirm whether my truck has the AAM 11.5 or 11.8?
    Check the axle tag or VIN-based build info. The 11.8 uses a 16-bolt ring gear and different hardware—our Yukon 11.5/11.8 overhaul kit is designed for 2014+ applications.
    Will high-capacity diff covers help when towing?
    Yes—heavy-duty covers like PPE and BD add fluid, cooling fins, and service ports to manage heat and make maintenance easier.
    Can I re-gear just the rear axle?
    On 4WD trucks, both axles must match. Pair front 9.25 ZF gears with the chosen rear ratio.
    Do traction bars affect ride quality?
    Quality systems like the BDS Recoil reduce axle wrap and wheel hop without binding suspension travel, improving stability under load.
    Not finding a year/trim-specific part?
    Our 19–24 driveline section is growing—call 724-785-4022 and we’ll match parts to your VIN and axle tag.
