2003–2026 Chevy Express & GMC Savana 2500/3500 – 2.5″ Rear Lift Kit (#404088-R)

The “Max Payload” Specialist | 5/8″ HD Hardware | 100% USA Steel

Built for the Heavyweights.

Let’s have some “Real Talk”: If you’re driving a 3500-series van or a 2500 built for max capacity, you aren’t just “driving”—you’re hauling. Whether it’s a fully armored cash-in-transit vehicle, a mobile plumbing workshop, or a dual-rear-wheel camper conversion, that back end is under immense pressure. Factory leaf springs eventually give up the ghost, leading to a permanent squat that ruins your handling and puts your rear bumper in the dirt.

The #404088-R is the heavy hitter. We provide a full 2.5″ of rear lift and include massive 5/8″ U-bolts. This kit is specifically designed for the rigs that outgrew standard hardware years ago.

🛑 THE “5/8-INCH” HARDWARE CHECK: > * HD Specific: This kit includes 5/8″ U-bolts, specifically designed for the heavy-duty rear axles found on most 3500 models and high-GVWR 2500s.

• Need 9/16″? If your van uses the standard 9/16″ hardware, you need the #404088-RT (which is a 2″ lift).

• Fitment: Chevy Express & GMC Savana 2500/3500 (2003–2026) 2WD 8-lug chassis.

The Highlights:

• 2.5 Inches of Rear Clearance: This is our tallest rear-only option. It’s the perfect way to level out a van with a heavy permanent interior build or to compensate for a massive towing tongue weight.

• USA Steel Toughness: We don’t use cast-iron blocks that crack or aluminum that corrodes. This is USA Mill Certified Steel, laser-cut and precision-welded in the American rust belt to handle the massive weight of a loaded 8-lug van.

• Professional-Grade Hardware: Most aftermarket kits cut corners on the bolts. We give you 5/8″ high-strength hardware to ensure your leaf pack stays secured under the most extreme loads.

• Direct Bolt-On Reliability: No welding or permanent modifications required. This kit is designed for the Chevy/GMC leaf spring configuration to maintain your factory ride quality while giving you the height you need.¹

• Fleet & Camper Approved: Stop scraping your hitch on every gas station entrance and start protecting your under-chassis investments.
