Low-profile roof rack cross bars for the 2025-2027 GMC Terrain with raised roof side rails (visible gap between rail and roof).

- Anti-theft security: Integrated lock & keys help deter removal.
- Accessory-ready: Works with common roof rack mounts — U-bolt compatible and top channel sliders/T-bolts.
- Adjustable width: Sliding clamps let you set ideal front/rear bar spacing on the Terrain raised rails.
- All-weather build: Rust-resistant aluminum, coated hardware, and rail-protecting rubber pads.
- Lower wind noise: Aerodynamic crossbar profile helps reduce drag and noise.

Fitment Tip: For the 3rd-generation GMC Terrain (2025-2027 model years) with factory raised roof side rails only — the rails sit above the roof with a visible gap underneath. Roof rails come on AT4 and Denali models and are optional on Elevation (Elevation Premium Package or Black Edition); factory roof rails required — an Elevation built without side rails is not compatible. Not for 2010-2024 Terrain models (different roof), bare roofs or flush rails. If your Terrain has the panoramic sunroof, check the clearance between the bars and the glass before opening it with the rack installed.
Rack capacity is 220 lb. Your vehicle's factory roof load limit may be lower — follow your owner's manual.

Quick Install Guide
- Insert mounting brackets into the aluminum crossbars.
- Place bars on the roof and mark positions on the raised rails.
- Adjust feet to match your rail size; pads must sit flat.
- Tighten evenly with the supplied hex key until seated—do not overtighten.
- Re-check all fasteners on both sides; bars must not move by hand.
- Confirm rubber pads and plastic covers are aligned and fully seated.
- Close end caps and lock the feet; store the spare key safely.
- Do not use with an open sunroof; verify clearance after install.
Tip: The Terrain roof is narrower at the rear. Install the shorter bar at the rear and the longer bar at the front.
Correct Bar Orientation
Install with the profile’s front lip facing the vehicle’s FRONT. Both crossbars must face the same direction; incorrect orientation can increase wind noise.
Confirm your GMC Terrain has raised roof side rails before purchase. Never exceed the lowest-rated component (vehicle roof, rails, bars, or accessories).
