How do I know if this part fits my vehicle?

Description

Bolt-on 3.5"–5.5" of front lift on a true fabricated spindle — keep your factory ride and handling while clearing up to 35s. Built in the USA for 2007–2018 Chevy Silverado / GMC Sierra 1500 2WD with cast-steel O.E. suspension.

Three lift heights in one kit

  • 3.5" — spindles only
  • 4.5" — add the +1" spacer (clears 33s)
  • 5.5" — add both spacers (clears 35s with minor trimming)

What this stage includes

  • CST fabricated lift spindles and 2 pairs of lift spacers
  • 3" fabricated rear lift blocks and U-bolt kit
  • DOT-approved steel-braided brake lines and all hardware
  • Reuses your factory front shocks — rear shocks sold separately

Why CST

  • Laser-cut 1/4"+ steel, fully MIG-welded — engineered and built in-house by CST in the USA
  • CNC-machined ball-joint tapers for a precise O.E. fit
  • Retains OEM ride quality and handling, with minimal track-width change — no bump-steer or premature wear like import knock-offs
  • Up to 5.5" front / 3" rear of lift, and fully reversible to stock

Good to know

  • Max wheel backspacing: 5"
  • Tire-clearance figures are based on 8–8.5" wide wheels
  • Professional installation and alignment recommended
