Measure 1) the width and height of your truck bed and 2) the space between the wheel wells and the cab. Knowing these measurements will allow you to select a box that fits your truck properly. 3-Layer Laminated RSL Rigid Structural Lid has a reverse beveled edge liner and an inner layer of rigid foam insulation to create the most rigid, strongest aluminum lid we've tested Adjustable lid strikers lock the lid down tight for superior security Reinforced body resists cargo damage and protects the lock system Gas spring lid lifts raise the lid when unlatched for easier access
