    Prinsu is considered a staple and leader in the industry when it comes to quality roof racks and top racks. The Prinsu GMC 1500 universal top rack continues this long running legacy and is perfect for those GMC owners who are sick of carrying their gear in the backseat or those looking to free up space in their bed. The Prinsu top racks come in different sizes to fit many bed lengths and it features a completely bolt on installation.

    Prinsu top racks including this Prinsu universal top rack are designed to be installed on the top of a fiberglass topper/camper (Leer, A.R.E., SnugTop, etc.). Whether you are looking for a long bed rack or short bed rack, Prinsu has something. These rack systems install directly to Yakima Thule tracks mounted on the topper. This allows the top rack to be installed without drilling.

    Included with the GMC 1500 universal top rack are two laser cut side plates constructed out of high quality aluminum, 2x1 inch aluminum crossbars with drop in slots, Prinsu mounting feet allowing you to attach the rack to the tracks on your topper, and all necessary installation hardware. For wider toppers you will need to mount the rack using the Leer mounting feet offered by Prinsu.


    How much wind noise does the GMC topper Prinsu rack generate? The GMC topper roof rack features an extremely low profile design so the amount of wind noise caused by the rack is very minimal. Please note that if larger items are mounted wind noise may increase.

    What accessories can I mount on the GMC Sierra Prinsu topper rack? The GMC Sierra Prinsu rack is perfect for mounting accessories including roof top tents. Prinsu racks feature drop in points for easy mounting. This means all Prinsu accessories will attach to the GMC topper rack including the Universal MAXTRAX Mount, Prinsu Ridgeline Handles, and more.

    How much weight can the GMC Sierra Prinsu top rack support? The Sierra topper rack's aluminum construction keeps weight to a minimum. But that does not mean it doesn't have an impressive load capacity. The static load capacity is upwards of 600 lbs. with the dynamic load capacity being about half of that. Please check the ratings on your camper shell before loading it as the shell might have a lower rate rating.
