CST 3.5-5.5" Spindle Stage 1 Suspension System — 07-18 Chevy / GMC 1500 2WD (Cast Steel OE)

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
