66-77 Bronco 1.5″ Performance Package

From: $4,592.53

Before Purchasing:

The Huck 1.5" performance package will not require a drop pitman arm or drop track bar bracket.

This suspension system will not work with any TRO - Tie Rod Over steering setups. TRU - Tie Rod Under the knuckle only.

The leaf springs included in this system are designed for Broncos with close to equal weight front to rear. If you have a half cab or roadster it’s likely that the rear of your Bronco will sit a little high due to being lighter in the rear. If you are installing this system on a well-equipped Bronco with most of these aftermarket additions – Plate bumper, 20-gallon+ fuel tank, HD tire carrier w/ 33″ or bigger tire, hardtop, tools/gear, back seat. You may find that you need to install our add a leaf, 1/2″ lift blocks (5539) or pinion shims after your suspension has settled in.

Disclaimer: This add a leaf will not make your Bronco ride stiffer and it is only designed for our new 1.5″ leaf spring.

Information

New for 2023

For years you could only have Duck Tuff 2.5" Performance Suspension Package as the end all be all for best riding and handling and on and off-road for all Early Bronco Enthusiasts. Then we developed the 1.5" lift system and we are blown away at how well it performs too.

If you are looking for a great suspension system that has everything you need to get your Bronco handling amazing on and off-road, this is it. Combining a 1.5" suspension lift with a body lift and fender flares will give you the perfect tire size and stance without the driveability challenges taller suspension lifts bring. Mount a 33" or even a 35" tire when combining a 1" or 2" body lift and fender flares and be as amazed as we are at how well your Bronco will perform on and off road. We call this the "wife friendly" lift as it allows for a lower stance with easy handling and control. We believe in confidence behind the wheel that inspires you and your family to get out there and enjoy on and off-road together.

  • Progressive Coil and Leaf Springs for Smooth on-road handling
  • Long Travel Shock Mounts for great articulation and comfort
  • Outstanding traction control (complete kit with all options)
  • Greatly reduced body roll on-road (front sway bar kit)
  • Driver AND Passenger confidence

Have you ever longed for your Early Bronco to drive and handle like a modern-day SUV? Do you want to drive it down the road and not ride like a log wagon and buck you all over the road? Are you worried if you go too fast, you won't be able to control it when it hits a big bump or something or someone darts out in front of it? Finally, a performance package that doesn't just lift the Bronco. It not only controls the best but also holds true to its original heritage. The leader of premium off-road Bronco parts, James Duff, is back to deliver you the best. Try it today and instantly save money, hassle, and time.

FAQ

Q: What tire sizes can I fit with this lift?
A: This lift can fit stock to 35" tires. It all depends on what you want. We can give you the best advice on lift and tire size here in our main FAQ.

Q: Why doesn't this system include a rear sway bar?
A: For this system, we don't recommend installing a rear sway bar for a couple of different reasons, one because of the tight packaging with the torque tamer and small lift, and two because it will limit rear suspension travel even when disconnected. 

Q: How difficult of trails can this 1.5" Performance Package handle?
A: With the correct body lift and cut fenders, a Bronco with 33" to 35" tires with this Performance package can do medium level trails and depending on the driver's experience level, some harder trails too.

Q: Can I install this in my driveway or garage?
A: Yes, but it will require, several tools, a degree of mechanical knowledge, welding, and an alignment. Consider this a challenging erector set that will take several days to install. Monster Mike at the Bronco Garage rates this install at a 5 out of 10

Q: What degree C bushings are on Huck? 
A: Huck is running 7-degree C bushings for optimal caster. The caster created by this kit on Huck is part of why it handles like a modern suv. 

Q: Can I mount the steering system over the knuckle?
A: For the 1.5" system we do not recommend mounting the steering in a TRO configuration as parts will collide with the frame and oil pan. 

Q: Do I need to purchase driveshafts?
A: For this system, with minimal lift, most likely your factory driveshafts will work fine. We highly recommend that you have them inspected and serviced if required.

Q: Can I use my stock sway bars with this lift?
A: No you can't. You will need to run the ones provided with this lift

Q: Can I purchase Extended radius arms instead of T-rex arms with this system?
A: No. They will collide with the frame when compressing the suspension. We recommend you do not buy this system if you want something different. You can create your own lift system using the parts we sell if you would like something different than what is offered here.

Q: Can I purchase longer shocks and shock mounts with this system?
A: No. The shocks and shock mounts offered with this system provide all the shock you need. We recommend you do not buy this system if you want something different. You can create your own lift system using the parts we sell if you would like something different than what is offered here.

Q: Can I get this lift in a different color?
A: This system is offered in Duff's signature blue powder coat or Midnight Series Metallic Black powder coat. 

Q: What are the specs on Huck's tire sizes?
A: Huck features a 33"x12.50" Mickey Thompson Baja Claw as pictured.

Q: What shock mounts does this system include and do they require any welding?
A:  This system includes our 0-1" long travel front mounts and our classic rear mounts for more shock travel. You will be removing the factory shock mounts that came with your Bronco and you can bolt or weld the front mounts and the rear mounts are weld on only.

How to Buy

How to spec out your 1.5" Performance Package...

With such a comprehensive kit and the options it comes with, we have designed an interactive configurator to help guide you through selecting all the correct parts. Take some time to get familiar with the options and selections and read the information at each step to help guide you through what you need and why.

Accessories and add-ons may require you to do a little more research on what your Bronco already has and what may or may not have already been done to it. After 50+ years of being on the road, the Bronco could have had several different parts added and removed on it.

This performance package comes standard with 7 Degree C bushings.
