What are the differences between the Rhino-Rack Pioneer Backbone systems for a 2021 Jeep Wrangler Unlimited hard top?


Expert Reply:

There are a few differences between the Pioneer Backbone systems available for your 2021 Jeep Wrangler Unlimited with a hard top. Two of the recommended systems are the Rhino-Rack Pioneer Platform Rack with Backbone Mounting System - 72" Long x 56" Wide # JB0893 and # JB0892. These two systems are basically the same thing, but the difference is that the # JB0893 has the Rhino-Rack quick-release leg system. This means that if you plan on removing the platform rack and then putting it back on then this would be the better option because you just have to squeeze 2 levers on the inside of the feet instead of having to remove hardware. Both of these systems come with the spacer mounts so that you can add additional height to your setup.

If you want the 72 inch x 56 inch Pioneer system without any spacers and without the quick release legs, that is part # RR78FM. For an option that has the quick release legs and rubber bases to add extra cushioning between the legs, that is part # RR88FM.
