Muscle car restorers and vintage GM enthusiasts who want to transform their open 10-bolt rear into a positraction unit will find the YDGGM8.2-3-28-1 Yukon Gear DuraGrip to be the definitive solution for the GM 8.2 inch 10-bolt rear axle. Part number YDGGM8.2-3-28-1 fits GM 8.2 inch 10-bolt axles with 28-spline shafts and 3.08 and numerically higher gear ratios, covering the wide-spread carrier application for early Camaro, Chevelle, Nova, El Camino, Caprice, and related platforms from the 1960s and early 1970s. The YDGGM8.2-3-28-1 uses composite clutch technology and forged 4320 steel spider gears inside a nodular iron case for a clutch-style limited slip that delivers reliable power delivery to both rear tires throughout cornering and acceleration.

What is the GM 8.2 inch 10-bolt and which vehicles use it?
The GM 8.2 inch 10-bolt is the original small-block rear axle found in early-to-mid 1960s through early 1970s Chevrolet A-body and F-body cars including Camaro, Chevelle, Nova, El Camino, Impala, and related Pontiac Firebird/Tempest applications.
How do I know if my muscle car has 28-spline axles for YDGGM8.2-3-28-1?
Most GM 8.2 inch 10-bolt applications came with 28-spline axles. Count the splines on one axle shaft after removal to confirm before ordering.
Does YDGGM8.2-3-28-1 fit both the 3.08 and 3.73 ratio carriers?
Yes. The YDGGM8.2-3-28-1 covers the wide-spread carrier range, which encompasses 3.08 and all numerically higher ratios for this axle. For 2.73 through lower ratios, a different carrier is needed.
Will this fit the later Chevy 10-bolt like the 7.5 or 8.5 inch?
No. The 8.2 inch is a specific older design. For GM 8.5 inch 10-bolt applications, see YDGGM8.5-3-28-1 or YDGGM8.5-3-30-1.
What gear oil does Yukon recommend for YDGGM8.2-3-28-1?
Yukon Gear recommends high-grade non-synthetic GL-5 gear oil with Yukon LSD additive (part number OILADD). Synthetic oil is not recommended and may cause clutch chatter in this unit.
Does the Magnuson-Moss Warranty Act apply to classic cars?
The Magnuson-Moss Warranty Act applies to any warranty still in force. For classic vehicles that are out of their original warranty period, the act is less directly applicable, but the principle holds that an aftermarket part alone cannot be used to void warranty coverage on any remaining powertrain warranty.
Can YDGGM8.2-3-28-1 be used in a drag racing application?
Yes, the DuraGrip design is suitable for street and bracket drag racing. The composite clutch packs allow smooth two-tire launches. For full-lock applications on a purpose-built drag car, a spool would be more appropriate.
Is the YDGGM8.2-3-28-1 rebuildable?
Yes. Replacement clutch packs and spring kits are available from Yukon Gear so you can rebuild the unit without purchasing an entirely new differential.
