2018-2024 Wrangler JL 4 Door Backbone Mounting System 3 Base (RJLB1)

The RJLB1 brings the Backbone interior frame to the four-door Wrangler JL. 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).

Features

• Interior frame plus three mounting plates per side of the hard top
• Raises the roof load rating to 264 lb (120 kg)
• Vehicle-specific design for the JL four-door hard top
• Mounting system for a Pioneer platform or two-bar rack (sold separately)
• Packs at 26.4 x 23.3 x 5.3 in

Specifications

• Max load rating: 264 lb (120 kg)
• Plates: 3 per side
• Weight: 32.0 lb
• Packaged dimensions: 26.4 x 23.3 x 5.3 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.
