GMT800 +2 Long Travel Kit — Now Shipping from FENIX Motorsports

If you've been waiting on a long travel front end for your 99-06 GMT800 that doesn't force you to source ball joints from three different vendors and reinvent your steering geometry from scratch, the wait's over. The FENIX Motorsports+2 Long Travel Kit is live, built to order, and ready to go under your truck.

This one's been a long time coming. It's the first suspension release under the FENIX Motorsports name, and it's built the way we build everything — in-house, on our own jigs, with a spec sheet we're willing to stand behind.

What Is the +2 Long Travel Kit?

The +2 kit widens front track width 1.875" per side while retaining as many factory, off-the-shelf components as we could reasonably keep in the design. That's not an accident — a long travel kit that requires you to hunt down discontinued ball joints or one-off spindles two years from now isn't actually long travel, it's a liability. Keep stock uprights, brakes, and wheel hub assemblies in the mix, and your truck stays serviceable at literally any parts counter in the country.

Where it counts, though, this isn't a stock-plus kit. You're getting:

• 1" uniball spherical bearing in the upper control arm
• 3/4" heim joint steering conversion with new tie rods
• Dual shock configuration running 2.5x8 coilovers and bypasses (shocks sold separately — run what you want)
• Up to 10" of travel with stock fenders, up to 13" with clearanced or fiberglass fenders
• 0–2.5" of provided lift
• Compatible with hydraulic bump stops and limit straps (we recommend both)

Construction is 3/16" boxed material with internal ribbing throughout — this is a front end built to take repeated high-speed impacts, not a leveling kit wearing a long travel kit's marketing copy.

One thing this kit does not retain: your stock sway bar. If disconnects and sway bar delete aren't already part of your build plan, factor that in before you order.

Fitment — Read This Before You Buy

This kit is designed for 1999–2006 and 2007 Classic body style GMC Sierra and Chevrolet Silverado 1500 trucks.

Straight talk on 2WD vs. 4WD: we've validated fitment on 4WD trucks in-house. It's engineered to fit 2WD trucks as well, but we haven't run a 2WD truck through the shop yet to confirm it in person. If you're running a 2WD GMT800 and want to be an early build on this kit, reach out before you order — we'd rather talk through it with you than have you find out something doesn't line up after the welder's already out.

If you're running 4WD, there's a bigger fitment note: this kit requires swapping to GMT900 axles (from a 2007–2018 GM 1500 truck) to run 4x4. This is a common long-travel-kit requirement across the GMT800 aftermarket, not a FENIX-specific quirk, but it needs to be part of your budget and parts list from day one — not something you discover mid-build.

Also plan your wheel order around this kit, not after it: you'll need 4.5" of backspace to clear everything properly. Wrong backspace is one of the most common — and most avoidable — reasons a long travel install stalls out.

Installation

This is a cut-and-weld kit. It touches safety-critical suspension components, and we mean it when we say installation by an experienced fabricator or off-road shop is highly recommended. If you've got the welding chops and the jig setup to do it right, have at it — but this isn't a bolt-on weekend project, and it shouldn't be treated like one.

Availability & Pricing

The +2 Long Travel Kit is $3,999.99 and currently built to order, with a 2–4 week lead time to fill orders. Every kit is fabricated in-house after it's ordered rather than pulled off a shelf, which is how we keep the spec consistent from kit to kit — but it does mean this isn't a same-day-ship item right now. Plan your build timeline accordingly.

As with all of our built-to-order and freight items, all sales are final once the order is placed.

What's Next

The +2 kit is the first piece of a larger GMT800 suspension lineup we're actively building out — more travel options, more hard parts, and more of the platform-specific stuff that's been genuinely hard to source for these trucks without settling for universal-fit parts that were never actually designed for a GMT800 chassis.
