Product Details

Important Notes:

  • Requires a maximum 4-3/4" backspace wheel or wheel spacer with factory wheel setup. 4-1/2" back spacing is recommended


The Stage 4 System is for those wanting maximum performance and capability without sacrificing ride quality. It carries over the quality components of the Stage 3 System, but improves upon them by swapping out the Standard Length Control Arms for Adjustable Long Arms and Long Arm Mounting Brackets. This is a 100% bolt on system with no welding required. This system will fit 37" tires with stock fenders or 40" tires with high fenders.

Product Details:

  • Stage 4 key features are front and rear track bar relocation brackets, flipped drag link, and all adjustable upper & lower long arms
  • Front and rear bump stop extension kits and Front and rear sway bar links
  • Front and rear extended stainless steel braided brake lines and Front and rear lower shock mounts
  • Synergy double adjuster sleeve & pinch bolt assembly allows for adjustment of control arm, track bar, tie rod, and drag link length without removal
  • Front and rear track bar relocation brackets raise track bar mounting positions increasing suspension roll center heights which improves handling on and off road
  • Lower control arms are manufactured from high quality crush resistant 2" X .250" Wall 1026 DOM tubing
  • Features Synergy Dual Durometer Bushings (DDB) with Teflon® bearing surface for a maintenance free design focusing on performance, flex, longevity, and ride quality.
  • Progressive wound coil spring manufactured using the latest in CNC hot winding technology keeps spring from coming unbound at full suspension droop
