Description
Description
A true 8–10" of lift on a one-piece adjustable subframe — for 2011–2019 Chevy Silverado / GMC Sierra 2500HD, 3500 & 3500 Dually (2WD & 4WD). Trophy-truck-derived geometry that keeps factory track width and StabiliTrak happy. Pick your stage from the dropdown to set the shock package.
What every stage includes
- One-piece gusseted subframe with a full-size steel diff skid plate
- Fabricated CNC-machined front knuckles
- Heim-supported steering drop center-link
- Diff-drop, bump-stop, brake-line, and torsion X-member drop brackets
- Extended sway-bar end links and built-in stabilizer brackets
- DOT steel-braided front brake lines and all hardware
- CST soft-ride rear leaf springs, U-bolt spring plates, 1" blocks, and zinc U-bolts
Choosing your stage
- Stage 1 — base lift; reuses your factory front shocks (rear shocks sold separately)
- Higher stages add CST DIRT-Series 2.0/2.5 front and rear shocks, up to PRO-Series adjustable shocks
- “Ball Joint UCA” options add boxed ball-joint upper control arms with OE-style bushings
Why CST
- Same subframe architecture as the 6-8" kit, with taller geometry for 8–10"
- Retains factory O.E. geometry and track width — no StabiliTrak issues
- Built in-house by CST in the USA — no cutting or welding, reversible to stock
- Clears 37s (38x13.50/14.50 with minor trimming at 10")
Good to know
- Soft-ride rear leaf springs are not built for towing — add air bags for any load rating
- Torsion keys required for 9–10" of front lift (38s)
- Front CV driveshaft recommended on 2011–14 and required on all 2015+ at 8–10" (CSP-C28-5/-7 plus shift-linkage bracket)
- Wheel backspacing: 17–18" — 5.25"; 20"+ — 5.75"
- Approved on 3500/Dually; professional installation and alignment recommended
