RHINO-RACK Pioneer Platform + Backbone Rack System Kit (Jeep Wrangler JL '18+ 4dr Hardtop)- 3 Base

Platform Legs
SKU: RR-JC-00456

A complete kit with everything you need to add a frame-supported rack system to your Jeep Wrangler JL 4 Door Hardtop!

PLEASE NOTE: Free shipping (within the US) is available on Rhino Rack Backbone Systems and Pioneer Platforms (including this kit). We also offer installation services at either of our two California locations for all Roof Racks and accessories that we carry.

PLEASE NOTE: Drilling into the hardtop is required to install the Wrangler JL Backbone System. Butyl mastic and hardware are used for a secure and leak free fit. This kit is compatible with the 2021 JLU as long as it has the standard three-piece hardtop. It is not compatible with the new Sky One-Touch power top. 

If you like the Backbone system for the JL but would prefer cross bars (instead of the Pioneer Platform), have a look at the Jeep JL Vortex Cross Bars + Backbone Kit. If you're thinking this looks awesome, but you have a Wrangler JK not a JL, check out the JK Pioneer Platform + Backbone.

Wranger JL Hardtop Pioneer Platform + Backbone Rack System Overview

The wait is over for Jeep JL owners. Rhino-Rack's Wrangler JL Backbone Mounting System is now available. The Backbone provides internal skeletal support frames for the included mounting plates. Interior integration of the Backbone support frames creates a series of 3 incredibly robust base mounting points on each side of JL hardtop roof.

Heavy duty metal legs (there are two leg variations to choose from for the JL) are then attached to the 3 base mounting points. Lastly, a 76" x 56" Pioneer Platform is mounted to the legs. With the Backbone + Pioneer Platform you can carry 265 lbs on the roof of your Wrangler JL- and have access to the full suite of Pioneer Platform accessories and bracket sets.
