1966-77 Bronco Chassis RS4

$39,995.00

With the growing popularity of the classic 4×4 off-road market, RS saw the need for a well-engineered, complete, bolt on, high-performance four-wheel drive chassis.  The 1966-77 Early Bronco direct fit chassis marks the first release in the RS4 product line up.

Starting with Roadster Shop’s proven laser rails, a complete chassis was engineered utilizing the best components available in the industry.  Currie Dana 44 front and Dana 60 Rear differentials are tied into the chassis through triangulated 4 links designed to optimize anti-dive, anti-squat, and suspension articulation.  Massive sealed xAxis flex joints allow increased misalignment, longevity, and performance over commonly used spherical and Johnny joints.  Fox Racing 2.5 Factory Race Series coilovers tuned with RS specific valving offer the best of both ride quality on road and off-road performance.  Cad Optimized front steering geometry eliminates bump steer entirely while laterally controlling the axle.

Massive 5”x2.5” .188 wall frame rails provide significant strength gains over the undersized stock chassis. 3.5” of additional width inside the RS4 chassis allows simple header installation and steering routing making Coyote engine packaging ideal.  All popular classic and modern engine and transmission combinations have standard mounting provisions available.  All original mounting locations have been engineered into the RS4 Bronco chassis to allow easy bolt on installation with zero cutting to your body.  Ride height has been optimized eliminating the need for body lifts.  Bolt on rear shock mounts and desirable track widths allow the RS4 to be easily configured for either uncut, original rear wheel openings or popular bolt on flares.  Splined front and rear sway bars with 7075 billet arms and Fox Bump stops are optional along with a long list of engineered options to help assist and expedite your Bronco build.
