The new Ford Bronco is extremely unique and Belltech has engineered phenomenal products that enhance ride quality and performance. This highlights the 9943 anti-sway bar set which includes front and rear bars designed specifically for the 2021+ Ford Bronco 4WD, accommodating height ranges from OE to 4" in lift. Belltech anti-sway bars are designed, tested, and manufactured in the USA. They reduce ?body-roll" and improve handling to get the most out of steering control. During testing, we found some Bronco?s do not come equipped with an OEM rear bar, by adding the rear bar we greatly improved the vehicle?s stability, resulting in improved safety. As with all Belltech products, our Research and Development team spent many hours designing the Bronco sway bars to perfection. We considered the many uses of the Bronco for different types of jobs, adventures, and everyday driving so we added 3 adjustable settings to each bar. This adds the opportunity to adjust for a softer or firm response in lateral control. The front 1-3/8" diameter and rear 7/8" diameter Belltech anti-sway bars are made from cold-formed solid steel to provide immense strength and durability plus we powder coated them to increase longevity. In addition to the supplied high quality mounting hardware, we include polyurethane bushings to decrease flex when steering. Belltech sway bars are manufactured to fit your specific application, we are positive you will be impressed by the ease of installation and elevated performance.
