An internal structural mounting system for the JL Wrangler four-door hardtop that distributes roof loads into the chassis instead of into the fiberglass canopy alone. Six aluminum castings mount inside the headliner; T50 exterior bolts match the factory hardware. Bumps the rated roof load to 264 lb. Does not interfere with Freedom Panel removal or canopy detachment. Pair with a Pioneer Platform sold separately.
