The Roadmaster Crossbar Style Baseplate Kit for all 2010-2018 Jeep Wrangler trims offer a strong, secure mounting point for tow bars that utilize a crossbar or quick-disconnect system. Constructed from high quality steel, this baseplate resists rust and wear over time. Installation is quick and efficient featuring a custom-fit design. Ideal for car-mounted tow bars or setups needing additional accessory support.
Note: A crossbar-style base plate kit is designed to be used with a car-mounted tow bar like the Roadmaster StowMaster, if using a motorhome-mounted tow bar like the Roadmaster Nighthawk, Falcon etc., you will need a crossbar adapter # 37674.
