1988-1998 GMC Sierra 1500 ROCK-IT Rack HMOR

Full modular steel HMOR ROCK-IT Rack for 1988-1998 GMC Sierra 1500 pickup trucks, including the 1992 extended-cab short-bed application. The 6.5-foot-bed configuration uses a 60-inch finished rack. The 8-foot-bed configuration uses a 96-inch finished rack. Rack includes runners and MOLLE side panels.

ROCK-IT is a modular platform, not a fixed-purpose rack. Slotted crossbars, runners, MOLLE panels, and bolt-on accessories let you change the setup as your needs change.

Top-surface mounting slots provide flexible attachment points for rooftop tents and other gear. Compatible rooftop tents and mounting hardware can often bolt directly through the rack without extra crossbar clamps or adapter brackets.

Add, remove, or reposition compatible ROCK-IT accessories as your build evolves without replacing the core rack system.

* 12ga Formed Steel Construction
Major structural components are formed from 12ga steel for a strong, rigid rack system built for real load support.

* Continuously Welded Corner Reinforcement
Reinforced pillar corners redistribute load through a high-stress area of the rack and help resist twisting and fatigue.

* 1,500 lb Published Load Support
Rated to 1,500 lbs static and smooth-motion dynamic load with weight evenly distributed. Do not exceed the vehicle manufacturer’s load capacity.

* Modular Accessory System
Slotted crossbars, runners, MOLLE panels, integrated wiring pass-throughs, and bolt-on accessories let the rack adapt as your setup changes.
