The WK Grand Cherokee brought about a complete makeover in the drivetrain department from the previous generation. The trusty 4.0L straight-six was finally put out to pasture in favor of a new 3.7L V6. But the headliner was the availability of Dodge's newest Hemi V8. Displacing 5.7L in standard form and 6.1L in SRT-8 Grand Cherokees, power numbers crept up to new levels for Jeep's premium offering.

From Bellhousings, Flexplates and Flywheels to Clutches and Torque Converters. Plus tons of the small pieces needed to button up or couple your transmission and drivetrain.
