The Ultimate systems take the Original Hoop System suspensions and carry it one step further with the addition of our eleven leaf soft ride springs. For 3.5″ lifts, they come in either medium-duty or heavy-duty depending on your vehicle specs.* By using replacement leafs instead of add-a-leafs, you greatly increase your ride quality and along with Original Hoops and our progressive rate coils, these springs provide excellent articulation without a body lift or major structural modifications. Articulation and comfort… the best of both worlds!

FAQ:

Q: How do I know if I need heavy or medium-duty leaf springs?
A: Check out our FAQ page to learn more about which leaf springs are right for you.

Q: Will I need sway bars?
A: You will notice your Bronco’s body roll increase in the turns. This is normal anytime you increase the suspension ride height. It is not unsafe at low speeds however if you want more turning control while driving and at speed, we do recommend you start with a front sway bar.

Q: Do I need frame to axle extended brake lines with this kit? Part# 3931
A: 
If you have not already upgraded your brake lines this would be a good time to consider doing so. 

Q: Do I need E brake cables? Part# 3756
A: 
No but again, if your original ones are needing to be replaced anyways or you plan to use the Bronco offroad we recommend you replace them with new extended ones

Q: Do I need new driveshafts?
A: 
We always tell our customers that every Bronco is different. Some need them, others do not. If you feel your driveshafts may be too short or need to be replaced contact us. Looking to buy? Our front driveshaft is here, and our rear driveshaft is here.

Q: Should I replace my steering while I am installing my new lift system?
A: It is strongly recommended. Check out our heim steer systems or our wildly popular bumpsteer eliminator kit.

Q: Do I need pinion shims with this lift?
A: 
Most likely, you will need to measure your pinion angle after installing this lift system. Here is a link to our pinion shims in case you do.

Q: Do I need to move my rear axle back when I lift my Bronco?
A: Bronco’s with rear cut fenders don’t typically need this but if you are uncut you might. Check out our spring perches here that allow you to move your axle back as well as give you an option to lift it up another inch if needed.

Note: Blue or Black choice will apply to the coil springs and shock boots If you have a ‘66 with the stock rear stud mount shocks, we recommend upgrading to either a #5500, #5215 or #5214 for maximum travel and performance.

    I have used all Duff products on my suspension. These products include, 3.5″ lift, steering stabilizer and radius arm adjustable drop brackets. Service is excellent and all products have been superior. I would love to send you some pictures if you will direct me.
