2007-10 4WD AVALANCHE, SUBURBAN, TAHOE, YUKON, YUKON XL,
DENALI, ESCALADE SUSPENSION LIFT KITS

All Truxxx lift kits are a direct bolt in, simple and easy to install with nothing more than common hand tools and require no modifications to your vehicle. These kits retain the stock ride quality of your truck. Alignment specs are included and the truck can be returned to stock. Truxxx kits are made in the USA out of the finest steel and we supply you with complete instructions including install pictures, alignment specs and dedicated technical support.

406012 Features: Lift kit increases the front height 1.5" to 2.5" from stock (each SUV has a slightly different rake from the factory) giving you the clearance you need to run up to 33" tires (16"-26" rims, stock offset) to fit without rubbing. No strut disassembly required

405030 Features: Kit lifts the front 3" as well as raising the rear of the truck 1", getting rid of the factory rake. Front wheel travel is increased 2" and stock ground clearance is greatly improved making off road or heavy construction use. Allows use of stock shocks. Brackets included. Allows for up to 33" tires to fit without rubbing & can be installed in 3 hours

6.5" allows 34 x 12.50

Back spacing: 4.5"w/17, 5" w/18, 5.75"w/20's

Zone's 6" system will give your ride the look as well as the on and offroad performance you are looking for. Custom valved replacement struts are included to properly handle the increased weight of the larger tires & wheels. The differential skid plate, additional strut bar, and 1/4" thick steel crossmembers create a sub-frame that is bulletproof. The CNC machined ductile iron steering knuckles ensure proper steering geometry as well as reduce installation time compared to a drop bracket system. The rear is completed with new coil springs, track bar bracket, and adjustable upper arms to correct the pinion angle. By far the most complete system on the market for the money!

Note: All wheel drive models require driveline  modification.

3" allows 285/75/17 with 4.5" BS
6" allows 315/75/R17 with 4.5" BS

Kit includes rear shocks. Maximum tire size 34x17. 

2007-09 4WD GM Tahoe, Avalanche 1500 6"-7" RCD lift kit utilizes front strut and spring preload assembly spacers for 7" of increased ride height. Stainless steel braided brakelines included and rear Bilstein 5100 shocks. Drive shaft modifications not required.

Clears up to 35x12.50 tires mounted on a 17x9 wheel with 4.5" backspacing, fender/ bumper/ valance trimming required. It is recommended to maintain the minimum factory wheel diameter. Trimming of valance/ bumper/ fender will be required with amount depending on wheel fitment and/or specific tire selection.

6" allows 33x12.50x17 with 5.5" BS

2007-10 4WD Avalanche K1500 replacement knuckle 6" lift kit installs quick and easy, plus the vehicle can be returned to stock later if desired. Includes crossmembers to relocate lower control arms, new cast ductile iron knuckles, differential skid plate and kicker braces with urethane bushings. Beefy lower control arm crossmembers, and the remainder of each system's load-bearing bracketry, are laser cut from 1/4" thick plate steel. Factory front drive shaft and rear factory shocks are retained. Does work with Stabilitrak.

6" allows following:
35x12.50R17 with 17x8, 5" BS
325/65R18 with 18x9, 5" BS

Fabtech lift kits for the 07-09 4WD 6-Lug Avalanche, Tahoe & Yukon incorporates Fabtech's one piece high arched lower crossmember design with an integrated differential skid plate for solid support of the front suspension. Replacement extended length steering knuckles were designed to keep the track width of the vehicle near stock while retaining turning radius. All rear systems feature extended length tubular upper and lower link arms with an oversized trac bar relocation bracket to properly place the axle under the vehicle with zero driveline vibration.  

Installation of all systems does not require relocation of the Rack and Pinion or disassembly of the front strut assemblies.  There are no brake line, exhaust system or driveline modifications required for installation. 

The Basic System features the above mentioned components along with front strut assembly spacers and rear performance coil springs.  

The Performance System provides the Dirt Logic 2.5 coilover front shocks for superior damping.  Rear shock options with this system include Dirt Logic 2.25 Resi Shocks for a total suspension upgrade. This system will provide a supple highway ride with outstanding offroad capabilities for the best of both worlds.  

Rancho's suspension system for the 2007-08 4WD Chevy/GMC 6-Lug SUV features a one-piece sub-frame to provide maximum ground clearance and superior strength to the vehicle. Precisely relocating the lower control arms and differential, the sub-frame is engineered to ensure that both suspension and drivetrain geometry is calibrated to the optimal setting. Front differential drop brackets correct pinion angle for minimized driveline vibration. High clearance aft braces and rear coil springs included.

Steering integrity is uncompromised by maintaining the stock location of the factory rack and pinion steering. This, along with the heavy duty CNC extended cast steering knuckles, maintains optimal steering geometry and results in a faster, easier installation.

Combined, these features allow for the reuse of the stock wheels and fits up to a 315/70/17 tire. (Fitment of the maximum tire diameter may require trimming or modification to provide proper clearance. Wheels under 17" in diameter cannot be used.)
