Our new JL cargo rack is designed for the JL/Gladiator Hardtop, and will hold all your gear up to 200 llbs. Our redesigned rain gutter mounts offer adjustable rubber bump stops that rest against the roof. This give our racks more stability and additional weight capacity, compared to our previous mounting clamps. The cargo rack attaches easily to the JL factory rain gutter, with no drilling required for installation. Rack dimensions: 54”W by 36”L by 4”H
