Quick Overview

For optimal service life and exceptional drivability, install the Superlift 6" knuckle lift kit on your Silverado or Sierra 1500. This design keeps the factory upper control arms in their original location while lowering the factory control arms.

Replacement steering knuckles span the increased distance between the control arms. The lower control arm crossmembers are constructed using 1/4" thick steel plate and are a one-piece, full width design. The front differential is protected by a skid plate that does not require the removal of cast reinforcement webbing as seen on other brands.

  • Driver and passenger side cast ductile iron knuckles
  • Front and rear crossmembers
  • Frame reinforcement bracket
  • Front sway bar end link
  • Differential drop bracket
  • Torsion bar drop brackets
  • Belly pan
  • Rear compression stop
