Notes:

  • Diesel models will require a set of spacers to be fabricated for installation. The transmission cross member is located further back on diesel models and the front long arm brackets will not sit flush to the cross member
  • Use Currie anti-rock rear sway bar kit with CE-9901RD2 14 inch end link rods if wanting to run a rear sway bar
  • Trimming of skid plate for clearance to front driveshaft will be required with stock driveshaft - aftermarket driveshafts highly recommended
  • Relocation of parking brake cables will be required, move from over cross member to under cross member
  • Additional bump stop spacing may be required for larger tires if air bump kits are not used
  • Springs retain the factory rake of the vehicle where the rear is higher than the front. Vehicle should sit level when loaded. Request one size shorter rear springs to level the vehicle out when unloaded (Recommended rear shocks will be too
  • long with 4.5 inch rear springs. We recommend limit straps, coil retainers, or shorter shocks be used.)
