The Backbone is the roof mounting system that lets a Pioneer platform bolt to a Colorado or Canyon Crew Cab without roof rails. Six stainless steel bases on each side tie into the roof and spread the load along the body, and the low, shaped profile keeps wind drag and noise down on the highway. It is the base layer only: the Pioneer platform sits on top and is sold separately.

Features
  • Six bases per side bolt directly to the Crew Cab roof
  • Carries a Pioneer platform (maker lists 42100B, 45100B and 41100)
  • Non corrosive stainless steel construction
  • Shaped to cut wind drag and road noise
  • Styled to suit the truck, not just bolted on
  • Drill bit included for the roof holes
  • Roughly three hours to install
  • Mounting system only, platform sold separately
Specifications
  • Material: stainless steel
  • Bases: 6 per side
  • Complete system weight (maker figure): 70.5 lb
  • Install time (maker figure): about 3 hours
  • Weight: 15.8 lb
  • Dimensions: 57.1 x 7.5 x 4.7 in

A Backbone and Pioneer combination is the overland setup for the mid size GM twins: a full length platform rated for real gear, mounted to the roof structure rather than to factory rails. Installation involves drilling the roof, so plan for a careful afternoon or a shop install.

Notes
  • Mounting system only. The Pioneer platform is sold separately.
