2007-2018 Wrangler JK 4 Door Backbone Mounting System 3 Base (RJKB1)

The RJKB1 Backbone is an interior support frame for the four-door Wrangler JK. Three plates on each side of the hard top connect to the frame inside the cabin, extending the roof line into a structure rated to carry up to 264 lb (120 kg) of roof load.

Features

• Interior frame plus three mounting plates per side of the hard top
• Raises the roof load rating to 264 lb (120 kg)
• Mounting plates accept a two-bar roof rack or a Pioneer platform
• All internal support frames come in the box
• Fitting hardware for the install is included
• Made for use with the RLT500 Quick Mount leg

Specifications

• Max load rating: 264 lb (120 kg)
• Plates: 3 per side
• Weight: 26.1 lb
• Packaged dimensions: 44.7 x 17.7 x 3.4 in

Because the frame runs inside the cabin and ties into the hard top plates, the Backbone spreads the load across the body rather than hanging it on the roof skin. Add a Pioneer platform or a two-bar rack on top and the Jeep is ready for real overland weight.

Notes

• Mounting system only. The Pioneer platform is sold separately.
