Leveling Lift Kit (3.5" Front / 2.5" Rear) for GMC Envoy & Chevy Trailblazer 2WD/4WD (2002-2009)

If you've ever looked at your Envoy or Trailblazer sitting nose-down with the rear end riding higher than the front, this GMC Envoy Trailblazer lift kit is built to fix exactly that. It's a leveling kit, not a full suspension overhaul — the idea is to raise the front to match (and then some) the stock rear ride height, which on these trucks tends to sag or simply sit lower than the back from the factory. In this kit you're getting 3.5 inches of lift up front and 2.5 inches in the rear, so you end up with a level stance instead of that factory rake, plus a bit of extra clearance all around for bigger tires.

Why This GMC Envoy Trailblazer Lift Kit Works the Way It Does

One thing worth explaining up front, because we get asked about it a lot: the spacer thickness itself is actually 2 inches front and 2.5 inches rear, not a straight 3.5/2.5 block of steel and urethane. Due to the geometry of the stock strut and shock setup, that 2-inch front spacer translates into roughly 3.5 inches of actual ride height gain once it's installed and the suspension settles. It's not a 1:1 relationship, and that's normal for this style of spacer-based leveling kit — it's how the factory control arm and strut angles react to the added spacer height. The rear spacers are closer to a direct correlation since they sit on the shock body itself.

The front pieces are shock spacer blocks that sit in the strut/spring suspension body, and the rear pieces work the same way at the rear shock mounts. Nothing about the install requires you to take struts apart or send anything out to a shop for disassembly — it's a spacer-based system designed to work with your factory shocks, springs, and mounting points as they already exist.

Built for GMC Envoy and Chevy Trailblazer 2002-2009, 2WD and 4WD

This kit is designed for the GMC Envoy and Chevy Trailblazer, model years 2002 through 2009, and it covers both 2WD and 4WD versions of each. If you're not sure which trim you have or how it fits your specific truck, reach out through our contact page and we'll help confirm fitment before you order.

Because this is a leveling kit and not just a lift, it's a popular pick for owners who plan to run larger all-terrain or mud-terrain tires without rubbing the fender liners, and for anyone tired of the nose-down look these trucks develop with age and mileage.

Specifications

• Package size: 27 x 20 x 11 cm
• Front lift spacer material: 20# steel
• Rear lift spacer material: PU (polyurethane)
• Mounting hardware material: 45 steel
• Application: GMC Envoy 2002-2009 (2WD/4WD), Chevy Trailblazer 2002-2009 (2WD/4WD)
• Package includes: 2x front lift spacers, 2x rear lift spacers, mounting hardware

Tire Fitment After the Lift

With this kit installed, most owners are running up to a 32" diameter tire without rubbing issues. Specifically, a 32x10.50 tire on an 8" wide wheel with a +12 offset clears without rubbing. If you're going with an 18" wheel, a 255/70R18 tire is a common pairing, and on a 20" wheel a 265/60R20 works well. As always, wheel backspacing and any aftermarket bumper or armor can change how much clearance you actually have, so measure your specific setup if you're right at the edge of these numbers.

Installation Notes

This is a 100% bolt-on kit — there's no strut disassembly involved, and it's designed to work with your factory OE shocks rather than requiring an upgrade. That said, we recommend professional installation. Anyone comfortable with front-end suspension work can usually get through it, but torque specs matter here and getting the geometry right on both sides makes a real difference in how the truck drives afterward. Also worth noting: because these spacers are measured and cut individually, allow for about 1-3mm of variance from side to side — that's just the nature of manual measurement in production and isn't a defect.

A few other things worth knowing: these spacers are precision CNC laser-cut, so the fit at the mounting points is tight rather than something you have to fight with, and since they're solid spacer material rather than a coil or air component, they won't lose height or sag over time. Ride quality and comfort stay basically the same as stock after the install — you're changing ride height and stance, not spring rate or damping.

What This Kit Is (and Isn't) Good For

If your goal is fixing that factory rake and running a slightly bigger tire with a leveled stance, this is exactly the kind of kit built for that. It's not meant as a heavy off-road lift replacement or a coilover conversion — if you're building a Trailblazer or Envoy for serious rock crawling, you'll eventually want a more comprehensive suspension package. But for daily-driven trucks and weekend off-roaders that just need to sit level and clear a bit more tire, this covers it well. For more on how lift and leveling kits affect suspension geometry generally, Wikipedia's overview of car suspension systems is a decent reference if you want the engineering side of it.

If you're unsure about anything — fitment, what's in the box, or how this compares to other leveling options — our FAQ page covers a lot of the common questions, and you can always reach out via contact us directly.

For questions about delivery timing, our shipping page lays out the details, and once your order is on its way you can check its status on our order tracking page. If you've got a Envoy or Trailblazer part you don't see listed, our request a part page is there so we can try to track it down for you. And if something isn't right with your kit after it arrives, our warranty page explains how we handle that.

Bottom line: this GMC Envoy Trailblazer lift kit gets you a level stance and more tire clearance with a straightforward bolt-on install — a practical fix for a common issue on these trucks.
