The H3 seats are a direct bolt in, however I had to swap all the seat belt buckles, airbag sensors (SIR), position sensor and wiring harness to adapt to my GMC Canyon. This mod is specific to the seat year and truck year. 2004 and 2005 year trucks only require the seat belt buckle sensor and position sensor where as the 2006 and later GMT355 trucks require a seat pressure sensor, position sensor and a seat belt sensor.

QUESTION: Do I have to modify the H3 seats bracket to mount them in my Colorado or Canyon truck?
ANSWER: No, The Hummer H3 seats have the same bolt pattern as the OEM bucket seats and will directly bolt in. You will need an 18mm socket for the 4 bolts.

QUESTION: What is the difference between the Deluxe bucket OEM seat verses the Hummer H3 Leather seat?
ANSWER: Other than the electronics, seat module and wiring harness the H3 seat is a little more firmer. The advantage of the H3 seat is it conforms around the individual by the use of a 6-way position manual controls located along side of the seat. The H3 seat back rest and kidney support is designed to keep the individual from moving around.

QUESTION: Are both seats the same height?
ANSWER: No, The H3 seat is several inches higher than the OEM Deluxe Bucket seat.

QUESTION: Comparing both seats, which one has greater seat travel?
ANSWER: The H3 seat can travel several more inches, front to back than the Canyon Deluxe Bucket seat.

Concerns About Safety and Alterations to the Front Passenger Seat

The front passenger seat in many GM vehicles is equipped with a passenger sensing system that will turn off the right front passenger's frontal airbag under certain conditions, such as when an infant or child seat is present. In some vehicles, the passenger sensing system will also turn off the right front passenger's seat mounted side impact airbag. For the system to function properly, sensors are used in the seat to detect the presence of a properly-seated occupant. The passenger sensing system may not operate properly if the original seat trim is replaced (1) by non-GM covers, upholstery or trim, or (2) by GM covers, upholstery or trim designed for a different vehicle or (3) if any object, such as an aftermarket seat heater or a comfort enhancing pad or device is installed under the seat fabric or between the occupant and the seat fabric.

Aftermarket Seat Heaters, Custom Upholstery, and Comfort Enhancing Pads or Devices

ON A GM VEHICLE EQUIPPED WITH A PASSENGER SENSING SYSTEM, USE ONLY SEAT COVERS AND OTHER SEAT-RELATED EQUIPMENT RELEASED AS GM ACCESSORIES FOR THAT VEHICLE. DO NOT USE ANY OTHER TYPE OF SEAT COVERS OR SEAT-RELATED EQUIPMENT, OR GM ACCESSORIES RELEASED FOR OTHER VEHICLE APPLICATIONS.

Many types of aftermarket accessories are available to customers, upfitting shops, and dealers. Some of these devices sit on top of, or are Velcro(R) strapped to the seat while others such as seat heaters are installed under the seat fabric. Additionally, seat covers made of leather or other materials may have different padding thickness installed that could prevent the Passenger Sensing System from functioning properly. Never alter the vehicle seats. Never add pads or other devices to the seat cushion, as this may interfere with the operation of the Passenger Sensing System and either prevent proper deployment of the passenger airbag or prevent proper suppression of the passenger air bag.
