We?ve designed a full-size 4-Door Bronco Roof Rack for use with models featuring the OEM hard top. The cross bars feature an arc?d design to increase luggage & cargo capacity. There are multiple mounting points on all 4 sides for lighting options and gear such as a hi-lift jack, shovel, and more. This was specially designed to be compatible with our 40-inch Light Bar Mount (LBBR-03) & 50-inch Curved Light Bar Mount (LBBR-01).
