The newest heavy-duty Ram trucks are a refined version of the previous generation; they share the same basic coil-link suspension design. All three lift heights feature new Superide coil springs. Different rated coils are offered for the Hemi and the heavier diesel and V-10 gas engines. The coils are matched sets with an improved rate curve and ride quality that is second to none.

All three lift heights feature new pre-set coil springs.  Different rated coils are offered for the Hemi and the heavier diesel and V-10 gas engines.  The coils are matched sets with an improved rate curve and ride quality that is second to none. The only other components used in the 2˝ front leveling kit are new Urethane compression travel-stops.  New Superide shocks are recommended with the 2˝ system, but not required.  2˝ lift options include a dual steering stabilizer, front dual shock system and TruSpeed speed sensor calibrator.

The 4˝ system also includes a dropped pitman arm for steering correction, specially designed compression travel stops for the front and rear axles, a new track bar relocation bracket, and all new axle-to-frame link arms to restore factory alignment specifications.  Optional Rockrunner swivel-links are available for those who demand optimal articulation and off-road performance.  Lift blocks raise the rear two inches to negate most of the factory nose-down stance.  The factory rear springs are well designed units so axle wrap-up is generally not a problem.

The 6˝ system is basically a taller version of the 4˝ lift. As with the 4˝ lift, the 6˝ is available with standard one-piece front axle-to-frame links, or with Rockrunner swivel links.  Refer to the Jeep XJ and TJ catalog sections for more information on the Rockrunner Series links.  A new transmission / transfer case mount lowers the assembly within its crossmember to reduce driveshaft angle and prevent driveline vibration.
