The Early Bronco, Bronco II & Ranger Specialists
Since 1984, we've been unleashing the potential of these great vehicles with suspension upgrades, engine conversions and a wide range of accessories. Many have overlooked the value of this new generation of agile smaller trucks and SUVs. With years of experience in Early Broncos, we could see the potential in the Bronco II & Ranger. We have believed in these versatile rigs from the beginning and made Fords our one and only specialty.

The Basic History
The Ranger 4x4 debuted in 1982 as a two wheel drive model with a 2.3L and a 6.75" rear axle. In 1983, the four wheel drive version, as well as the Supercab, came onto the scene. Followed in 1984, by the Bronco II, both were offered with a Dana 28 front axle and a 7.5" rear. The Bronco II came with the 2.8L carbureted V6. Rangers were powered by either a 2.3L four cylinder or the V6. In '86, the V6 increased in size to a 2.9L, and became fuel injected. Along with a mild front end restyle in '89, a 170 hp 4.0L V6 became optional in the Ranger, and the axles in these trucks were upgraded to a Dana 35 front, and an 8.8" Rear. In 1989, both the Ranger and Bronco II received facelifts in the form of a new front clip and interior design. The Bronco II continued on with the 2.9L until '90, when it was replaced by the Explorer.

The Explorer debuted with the '91 model year, with the 4.0L as the only available engine. They also featured the Dana 35 front end, and the 8.8 rear, with the leaf springs under the axle. In '93, the Ranger received another facelift with a new body style. In '95 Ford redesigned the Explorer with A-arm/Torsion Bar front suspension, with a redesigned engine crossmember to ease the installation of the 215 hp 5.0L V8.

For '98, a new 205 hp single overhead cam (SOHC) 4.0 became optional. The Ranger redesign came in '98, when it received the same suspension changes, but continued with the optional 170 hp 4.0L engine. Due to the complexity and variety of options on of these years, we have no plans to design suspension systems for them. We have our hands full with 1966-97 model years at this point!

We originally designed this long arm for the '78-'79 Big Bronco and quickly realized all the rest of you wanted a piece of the action. Now this kit can mount up to any C-Channel frame, and is a popular upgrade for '80-'96 Full Size Broncos, all Bronco II's, Rangers & Explorers. Don't have a solid front axle? No problem. Out source or spec your favorite front axle and this kit will get you started on your solid axle swap. Click here for the parts list. We've also had customers successfully use this kit on Econoline Vans, Jeeps, Blazers, Scouts, Hummers, and more!

Our proven Long Travel Extended Radius Arm is Designed for rugged off-road use while enhancing drivability. Fabricated out of 2" diameter, heavy wall DOM at a whopping 5/16" thick! For strength and safety we designed a separate cast steel head unit to mount to the C-wedges on the axle with your original C-cap or our new ones sold separately. These arms are 10 3/4” longer than a '66-'79 Bronco arm, moving the pivot point farther back. This vastly improves suspension travel & articulation but it doesn't stop there. These arms also improve handling & control for on road driving.

  • Proven Design since 2001
  • Bolt-in C-Channel Frame Mounts
  • 10 3/4" longer than stock
  • Built-in 4.25º of added caster
  • In stock ready to ship, no lead time, no waiting!
  • Backed by the best customer service in the industry
  • Big Tires? Due the offset built into them that's what these these arms are made for
  • Needing more articulation, more flex? Our extended arms will give you the most of any arm on the market
  • Strongest extended radius arms available
  • Made from 100% brand new American Materials
  • Comes powder coated with all necessary hardware
  • Just say no to janky designs and core charges!


Fabricated from all new materials; no core charges, no cutting or welding to 40-50 year old cast arms. Built in caster means better alignment and handling. A tight to the frame rear mount holds the arm with a high quality 1” bore Teflon lined and lubricated Rod End, keeping it closer to the frame for improved ground clearance and breakover angle. Tons of travel, a tighter turning radius, better ground clearance and improved handling all in one product! Includes arms, head units, rod ends, frame mounts, bushings and all necessary mounting hardware. Requires at least a 4” suspension lift for '78-'96 Ford Broncos. C-bushings are sold separately due to vehicle variations and lift height.

This kit includes arms, cross member brackets, specially designed frame brackets with a backside reinforcement and riser brackets for the brake lines. The arms are the same proven design that we've been selling for years! Combine with our Cast C-Wedges, C-Caps and Spacers to swap in a new Dana 44 or Dana 60!

Note that a High Pinion 44 or 60 needs about 8° caster, 5-6" lift on this axle will utilize the 4°C-Bushings #6004. Any more lift then that use 7°Bushings #6007. The caster numbers can be adjusted on all axles depending on what angle the C-wedges are welded onto the axle.

Because the shopping cart cannot calculate shipping properly on these, we will contact you to authorize with shipping charges after you place your order. Please note these are heavy duty, they come in two packages totaling 121lbs!

Our new T-Rex radius arms are a stock length version of our heavy duty long arms with a built in offset for additional tire clearance but unlike the extended arms, these are a direct bolt in to your existing frame brackets. They use stock style polyurethane bushings, no welding of new brackets is necessary. Yes, 100% bolt on! Why would we do such a thing? Many Bronco owners want an arm that can clear a larger tire when turning without having to grind, drill or weld on their frame. These arms work for stock height Broncos and up to 3.5” of suspension lift. The arms come with 4.25° of caster built in. Shock mounting is different than our extended arms, these utilize a single shock mount located on top of the arm for a tighter turning radius arm, similar to a stock arm. Come powder coated in Signature Duff Blue or upgrade to new Midnight Black Metallic. Includes all mounting hardware required including hardware in kit #HC5341.

  • 100% Bolt-in, No Welding Required
  • Improves ride and handling

Heavy Duty Motor Mounts Bronco II Ranger V8 302 Conversion
Our Price: $199.00
Sale Price: $169.00
You save $30.00!

Our new heavy duty design replaces the hard to find motor mounts necessary for doing a V8/5.0L swap in your 4WD Bronco II or Ranger. These mount a V8 block to the existing crossmember utilizing urethane bushings with 9/16" bolts to reduce engine vibration and engine torquing. They set the V8 up slightly higher than the original engine to make room for the oil pan. The engine crossmember must be drilled for the new motor mounts. With the mounts, you receive a diagram showing the location of the new 1/2" slots. Although every attempt has been made to provide you with the correct locations, there are some variations where the slot may need to be enlarged.
