2001-2005 Hummer H2 4WD Superlift 6″ Lift System Front Installation Instructions

2001-2005 Hummer H2 4WD Superlift 6″ Lift System Front Installation Instructions

Installation requires a professional mechanic. Prior to beginning, inspect the vehicles steering, driveline, and brake systems, paying close attention to the suspension link arms and bushings, anti-sway bars and bushings, tie rod ends, pitman arm, ball joints and wheel bearings. Also check the steering sector-to-frame and all suspension-to-frame attaching points for stress cracks. The overall vehicle must be in excellent working condition; repair or replace all worn parts. Read instructions several times before starting. Be sure you have all needed parts and know where they install. Read each step completely as you go.

NOTES:
• Rear lift is sold separately and includes its own instruction form.
• Prior to beginning the installation, check all parts and hardware in the box with the parts list below. If you find a packaging error, contact Superlift directly. Do not contact the dealer where the system was originally purchased. You will need the control number from each box when calling; this number is located at the bottom of the part number label and to the right of the bar code.
• A replacement front driveshaft is required. This driveshaft is sold separately and is available from Superlift (Part #3406).
• A special tool is required to load/unload the torsion bars (step 2). Other special tools are recommended to detach/attach the pitman/idler studs. Refer to the factory service manual.
• Front end realignment is necessary.
• This system utilizes the stock torsion bars, which normally yield the best ride quality. But, if the “final product” ride and handling seem too soft, heavier Gross Vehicle Weight Rating (GVWR) bars can be installed. Generally, heavier torsion bars are only needed to compensate for the extra weight of a winch or snowplow, or when the truck is subjected to extreme off-road use. Also, wider tires and wheels proportionally increase the leverage on the bars, which results in lower ride height and a “spongier” ride. GM offers torsion bars with various rates that are heavier than stock. Your vehicle’s existing torsion bar rate can be identified by a 3-letter code stamped into the bars’ ends. The code is also on an adhesive tag wrapped around the bars.
• An arrow on diagrams indicates which direction is toward the front of the vehicle.
• A foot-pound torque reading is given in parenthesis ( ) after each appropriate fastener.
• Do not fabricate any components to gain additional suspension height.
• Prior to drilling or cutting, check behind the surface being worked on for any wires, lines, or hoses that could be damaged.
• After drilling, file smooth any burrs and sharp edges.
• Prior to operating a torch or saw, protect any heat-sensitive components located in the immediate area by covering them with a water-saturated cloth. Most undercoating are flammable but can be extinguished using a water-filled spray bottle. Have a spray bottle and an ABC rated fire extinguisher on hand.
• Paint or undercoat all exposed metal surfaces.
• Prior to attaching components, be sure all mating surfaces are free of grit, grease, undercoating, etc.
• A factory service manual should be on hand for reference.
• Use the check-off box “□” found at each step to help you keep your place. Two “□□” denotes that one check-off box is for the driver side and one is for the passenger side. Unless otherwise noted, always start with the driver side.

2001-08 Hummer H2 4WD Torsion Bar Leveling Kit Instructions

2001-08 Hummer H2 4WD Torsion Bar Leveling Kit Instructions

The net amount of ride height increase depends upon the age and use of the vehicle, wheel offset, and numerous other factors. Stated torsion bar ride height in- creases are based upon factory specifications. If the torsion bars were “cranked up” at some point in the past, expect a corresponding reduction in overall height increase with the new torsion keys. Note that torsion bars, like any other spring, are subject to fatigue and sagging over time. Also, torsion bars have different ratings depending on how the vehicle was equipped from the factory. In some cases, installing heavier rated bars (which can be purchased from a dealer) may be the only solution to regaining ride height lost from adding heavy aftermarket accessories, such as a winch bumper or snow plow.

Trail Master Suspension recommends a certified technician install this system. In addition to these instruction , professional knowledge of disassemble/reassembly procedures as well as post instructions checks must be known. Attempts to install this system without this knowledge and expertise may jeopardize the integrity and/or operating of the vehicle.

Please read all the instructions before beginning the installation. Check the kit hardware against the parts list. Be sure you have all the needed parts and understand where they go. If anything is missing , do not proceed with the installation, call Trail Master Suspension to obtain needed items.

Product Use Information
As a general rule, the taller a vehicle is the easier it will roll. We strongly recommend , because of rollover possibility, that seat belts and shoulder harness be worn at all times. Avoid situations where a side rollover may occur.

Braking performance and capabilities are decreased when significantly large/heavier tires and wheels are used. Take this into consideration while driving, also , speedometer recalibration is necessary when larger tires are installed.

Do no add, alter, or fabricate any factory or after-market parts which increase vehicle height over the intended height of the Trail Master Suspension product purchased. Mixing with suspension lift voids all warranties. Trail Master Suspension makes no claims regarding lifting devices and excludes any and all implied claims. We will not be responsible for any products that are altered. The only exception to the above policy is combining a Trail Master Suspension torsion key leveling kit with a Performance Accessories body lift system.

Hummer Air Valve Installation Instructions

Hummer Air Valve Installation Instructions

To Install
1. Attach the CTI Line with the swivel nut to the air valve.
2. Remove the ―” X 20 Nyloc Nut from the Valve
3. Put the air valve in the valve hole and hold in place.
4. Place Stainless Washer on Inside of Wheel under the Nyloc Nut.
5. Hand tighten the ―” X 20 Nyloc Nut onto the air valve.
6. Put the 9/16” open- end wrench on the swivel nut.
7. Tighten the Nyloc nut with the Hand Ratchet and ū” socket while holding the swivel nut in place with open- end wrench.
8. Tighten the Nyloc nut until the O-ring on the air valve has been squeezed down to about ― or more of its width which means that you must tighten the nut down as far as possible, it’s designed to bottom out on the threads of the valve, so make sure it’s “tight”.
9. Once the Nyloc nut is tight, reverse the direction of the ratchet and hold that ratchet and Nyloc nut in place. Do Not Untighten the nut.
10. While holding the ―” X 20 Nyloc nut in place, use the 9/16” open-end wrench and the tubular steel line to simultaneously, un-tighten the swivel nut from the air valve.
11. When re-installing the CTI Line, hand tighten the swivel nut on to the air valve, and then tighten that nut with a maximum of about 1/32 to 1/16 of a turn.
12. DO NOT over-tighten the swivel nut, it is not necessary as it is very likely that a hand tight swivel nut will hold air pressure, but would not necessarily stay tight, so it must be slightly tightened as suggested above.
