2011-2021 Jeep Grand Cherokee WK2 Ring & Pinion Gears

Bigger tires on a WK2 look great until the drivetrain starts making clear what the regear-or-not debate actually costs — highway RPMs climb, fuel economy drops, and the truck never quite feels right. Matching 2011-2021 Jeep Grand Cherokee WK2 Ring & Pinion Gears to the final drive ratio to the new rolling diameter fixes all of that at the source.

 

Front and rear axle ratios need to match on the WK2 to prevent transfer case binding under acceleration, which means both ends get done at the same time rather than one at a time. The target ratio depends on tire diameter, and a few decimal points of difference changes how the truck pulls on the highway noticeably.

 

Getting the WK2 drivetrain in sync with the tires is exactly the job of 2011-2021 Jeep Grand Cherokee WK2 Ring & Pinion Gears.
