They utilize our removable hinges and a cam latch that secures to your stock striker— so you can switch back and forth with your hard doors easily! Suzy specifically requested the perfect armrest height, corner plate and close lower bar to keep your valuables from sliding out while on the trail. Made of .090 wall tubing for strength without being too heavy. A 1/2” hinge pin is built into the door that slides into a brass oilite bushing on the hinge.

U.F.O. Flares: Ultra-Flex-Original

U.F.O. Fender Flares


#1211 Front UFO Flares, Black or White $179.00 pair
#1212 Rear UFO Flares, Black or White $179.00 pair
#1211 & #1212 Combo buy both Front & Rear together & Save! $339.00

Space age material creates a flare that is out of this world! It is the most flexible flare we have ever seen! Yet, it still holds it’s shape in heat and doesn’t get brittle in the cold. These are very pliable and will conform to straight or “trail customized” sheet metal. Rears are 48" outside bottom tip-to-tip, inside 43.5". Fronts are 46" outside bottom, 39" inside. Referred to as original because they are made from our original style molds i.e.; the size is comparable to those we’ve been selling since the last century. However, they can be stretched to accommodate larger wheel openings. High gloss black or white, are paintable (with flex additive). Black welting and aluminum rivets included.


Twisty! Flexible!

Long Travel Traction Bar
Long Travel Traction BarWith low-geared axles and high torque motors, soft long travel leaf springs distort under power-this can cause damage to springs and blow u-joints. Ordinary long tube, fixed mount traction bars limit travel as the rear axle cycles up and down because the axle also needs to move back and forth. Our new traction bar has an "A" frame designed center link for strength and a utilizes a specially designed shackle to eliminate axle wrap. The bar runs between the mufflers, parallelling the drive line; protecting it. It also maintains proper u-joint and CV angles under power. The main bar attaches to the high clearance cross-member and shackle. The cross-member mounts up between the frame rails for maximum clearance and helps protect your CV joint and output shaft from trail obstacles. Compatible with our Dual Exhaust system; other systems may require some modification. Welding brackets to the housing is required.

Ultimate Power Steering System

This is a brand new custom built power steering box that bolts directly to the Early Bronco frame with NO drilling! Direct bolt up means this system is as easy as it gets for adding that much needed power steering to your Early Bronco. Our system uses a slightly modified version of our tried and true Saginaw Power Steering pump in combination with our specially built tight tolerance (for less slack in the wheel) steering box. Short 3 1/3 turn box means quick response and excellent control for a "sporty" feel. Cast in gussets on the box make for a stronger case to stand up to the stress bigger tires inflict. Stock pitman arm bolts right up. Sits the same distance below the frame as a stock box so factory steering geometry is maintained, so it works on stock height or lifted rigs. Comes with all necessary components including box, brackets, hoses, aluminum pulley for the pump, steering shaft coupler and all necessary hardware.
