The RCI Offroad Adjustable 12" Aluminum HD Bed Rack installs on Toyota Tacoma, Tundra, 4Runner, and Land Cruiser trucks to add secure, organized cargo storage without sacrificing bed space or adding weight. This universal-fit aluminum rack mounts to any truck bed and adjusts to match your specific bed width, eliminating the need for model-specific fabrication.

Universal Fit, Zero Compromise on Strength

Unlike custom-fit racks locked to one vehicle, the RCI 12" adjustable design works across multiple truck beds and generations. You select your bed length (three options available), then dial in the width to your truck's exact dimensions—no trimming, no guesswork.

  • Aluminum construction: Delivers the strength of heavy-duty steel without the weight penalty, reducing unsprung mass and fuel impact.
  • 12" height: Provides vertical clearance for gear stacking while maintaining aerodynamics and roof-tent compatibility.
  • Fully adjustable width: Scales from compact truck beds to full-size Tundra and Sequoia platforms in minutes.
  • Heavy-duty rated: Engineered to accept roof-top tents and stacked cargo loads without flex or deflection.
  • Quick-release mounting: Secures to bed rails with zero permanent modification to your truck bed.

Fitment: Toyota Tacoma, Tundra, 4Runner, Land Cruiser (All Generations)

This rack fits all generations of Toyota Tacoma (1st through 4th-gen), Tundra, 4Runner, and Land Cruiser, across all cab and bed configurations. Use the fitment verifier above to confirm compatibility with your exact configuration.
