Hummer

The Hummer Truck and SUV brands were first introduced in 1992 by AM General as a civilian model of the M998 Humvee. In 1998, the brand name was purchased by General Motors (GM). GM introduced three models: the original and military based Hummer H1, the Hummer H2 and the Hummer H3.

Hummer’s feasibility came into question amidst the 2008 economic downturn. The management team at GM placed it under review. Instead of being included in GM’s 2009 bankruptcy and being sent over to the Motors Liquidation Company, the model was retained to investigate its sale.

About Hummer Wheel Spacers

The Hummer H1 was the only model that featured the HUMMER grille letters. It was produced from 2002 to 2009. Buyers could use it as a pickup truck thanks to its modified rear that could accommodate a bed, or, as a dependable sports utility vehicle that could accommodate up to 7 passengers. The H2 was taller, lighter and slimmer than its predecessors. The latest model, which was built in 2009, came packed with a standard 6.2-liter V-8 engine that could churn up to 393 HP.

Hummer H2 wheel spacers are the best option when it comes to positioning your vehicle’s wheels. They offer accuracy and precision and can be used to clear your Hummer’s wheels for brake mods.

Hummer Bolt Pattern Chart

HUMMER & AM GENERAL  YEAR   BOLT CIRCLE
H1 & Humvee 88-09 8X6.5
H2 03-09 8X6.5
H3 06-09 6X5.5

The number of bolt and lug circles given for a specific wheel is referred to as “wheel bolt pattern”. It’s a measure of a circle imagined through the lug nut’s center. If you have a bolt pattern of 8-on-6 ½, 8 represents the number of lug nuts and 6 ½ the circle’s diameter.

  • Spare Wheel Nut 125 N·m 92 lb ft
  • Wheel Lug Nut 140 N·m 103 lb ft

Torque specifications for your wheel lugs are made for threads free from any grit, dirt or oil. Apply anti-seize lubricant only on the threads of the bolts and nuts and not on the seat of the wheel’s hardware.

The seat forms the basis for torque measurements and is the main point of friction. If an anti-freeze is applied to the bolt and nut threads, care should be taken as an excess of it can drip onto the lug seat causing inaccurate torque figures.

A thread tap or chaser can be used to clean off any obstructions or burrs from the threads. This allows the lug hardware to easily turn by hand until it reaches the lug seat. Once cleaned, use a torque wrench to tighten the lugs in a crisscross sequence. Be careful not to overtighten the wheel. This could strip the hub or lug nut, or, distort the brake rotor, brake drum or wheel.
