## Overview

The Rhino-Rack Backbone Kit for Jeep Wrangler JL Unlimited is an internal structural roof rack system that significantly increases your vehicle’s roof load capacity by 76%, supporting up to 265 lbs while maintaining easy removal of hard top panels. Featuring three mounting points per side, durable aluminum construction, and compatibility with Rhino-Rack accessories, it’s engineered in Australia for rugged durability and backed by a 5-year warranty.

## Description

The Rhino-Rack backbone is an interior structure set up on the inside of the Jeep JL Wrangler. Three plates on each side of the Jeep's hard top are connected with the interior frame extending your roof line to carry heavier loads with the max Load rating of up to 120kg or 264lb.

## Features

- INCREASED CAPACITY - Strengthen your Jeep Wrangler JL Unlimited hard top so that you can mount a Pioneer Platform & increase your cargo capacity. The Backbone adds structural strength, enabling a higher roof load limit & improves cargo carrying ability.
- THREE MOUNTING POINTS - The three mounting points on each side of the roof system add mountable capacity and weight distribution for a Rhino-Rack Pioneer Platform, Vortex Bars or Heavy Duty Bars. Perfect for Jeep Wrangler accessories.
- NO INTERFERANCE - Won't interfere with the removal of your Freedom panels or hard top, since the kit bolts to your hard top both internally with the reinforced structure and externally via the mounting brackets.
- CARRY MORE - 76% More load capacity (114lbs more) is what you get compared to a roof rack mounted directly to the hard top. The factory non-stationary cap is 150lbs, which means you get an additional 114 lbs carrying capacity with the Rhino-Rack Backbone.
- INTERNAL BRACKETS install around the window frame and bear the weight from the roof, carrying the load from the roof down into the vehicle's steel body, greatly reducing the roof load pressure. Parked max load is 795 lbs. Moving max load 265 lbs.
- INSTALLATION - Single person installation. Instructions included, video also available online. Some drilling required. All hardware included. Get your setup ready for Jeep accessories.
- ADD A PIONEER PLATFORM - We recommend adding the best Jeep accessory: the Rhino-Rack Pioneer Platform for maximum roof usage. Use SKU 52108F for the best fit, sold separately.
- FOR CROSSBARS - works with Rhino-Rack legs RLCP (x2) or RLT600 for crossbar mounting. Legs, spacer kits & Pioneer Platform are sold separately, as each person may wish to customize their setup to their needs.
- FIVE YEAR WARRANTY - We stand behind our product quality and offer a 5 Year Manufacturer Warranty for peace of mind. Quality matters. Our products are engineered to withstand some of the harshest conditions on Earth. Designed and engineered in Australia.
- ADVENTURE - At Rhino-Rack, we believe there’s an adventurer in all of us. It’s what drives us to create world-ready outdoor gear, born and proven in Australia. We believe life is better when we Make Space for Adventure.
