2007-2026 GMC Sierra 2500/3500 ROCK-IT Bars HMOR

HMOR ROCK-IT Bars for 2007-2026 GMC Sierra 2500/3500 are the leaner entry point into the ROCK-IT system. Formed-steel pillars and slotted crossbars create a strong, adjustable-width platform for rooftop tents, cargo, and accessories without the runners and side panels of the full rack. Choose two or three complete cross sections, then add compatible ROCK-IT runners and side components later to build into a full ROCK-IT Rack.

Select the height and mounting style shown in this product's options. Choose the number of cross sections offered for your application. If a Softopper-compatible option appears, select it only for the matching canopy setup. Review the mounting and fitment notes below before ordering.

Designed for 2007-2026 GMC Sierra 2500/3500 applications. Available heights are 12, 17, and 23 inches. Mounting options include HMOR Non-Track no-drill mounting or Retrax XR / Roll 'N Lock XT Bed Cover integrated T-slot rails. ROCK-IT Bars are sold by cross-section count rather than rack length, so no bed-length selection is required. Rack width is adjusted during assembly to match the truck bed. Select the configuration that matches your mounting system, desired height, and two or three cross sections.

Set of 2: 500 lbs Static & Dynamic. Set of 3: 750 lbs Static & Dynamic. Static = vehicle not moving. Dynamic = vehicle in motion. Rough off-road impacts can exceed normal dynamic conditions. Do not exceed the vehicle manufacturer's load capacity. Evenly distributed loads only.

Selected ROCK-IT Bars configuration includes either two or three complete cross sections as selected. Each cross section includes two formed-steel pillars and one slotted crossbar, plus rack-to-vehicle mounting hardware and assembly hardware. Black powder coat is included. Runners, side panels, and other full ROCK-IT Rack components are not included.

HMOR ROCK-IT Bars for 2007-2026 GMC Sierra 2500/3500 assemble as a bolt-together modular rack foundation and mount using HMOR Non-Track no-drill mounting or Retrax XR / Roll 'N Lock XT Bed Cover integrated T-slot rails. Rack width is adjusted during assembly before the crossbars are secured into position. Rack assembly hardware and the selected rack-to-vehicle mounting hardware are included. Confirm mounting system, rack height, cross-section count, and required clearances before installation.

ROCK-IT Bars form the cross-section foundation of the modular ROCK-IT system. Compatible ROCK-IT components can be added later to expand the Bars system into a Full ROCK-IT Rack where supported. Confirm compatibility for your specific vehicle and configuration before upgrading.
