Special Features

  • [PERFECT 2-INCH STANCE] — The most reliable way to lower the rear of your 1963-1972 Chevy/GMC C10 by a full 2 inches; designed specifically for trailing arm suspensions to achieve a clean, leveled look.

  • [GRADE 8 RUST-RESISTANT HARDWARE] — Includes heavy-duty 3/4" Grade 8 Zinc-Plated U-bolts and high-collar nuts; our hardware is engineered for maximum clamping force and won't rust or fail under stress.
  • [EASY BOLT-ON INSTALLATION] — A 100% bolt-on solution that requires zero welding, cutting, or permanent modifications; fits between the axle housing and trailing arms using basic hand tools for a quick shop project.
