Absolutely the best modification I have made to the drivability of my Bronco! I didn’t think my bumpsteer was THAT bad, but wanted to clean it up as best as I could. This kit completely eliminated the bumpsteer and the truck handles better all around. I can’t recommend it enough.
Troy Foxworthy (verified owner) –
This was the best upgrade I have done so far. I wish had ordered sooner, completely change the drivability of my bronco. Good quality product and fitment was spot on. Beefy heim joints works awesome. If you are on the fence about spending the money you wont regret, as long as your other steering components are good.
Christopher S Androw (verified owner) –
This kit is great. The support and patience of the guys at the Duff shop is amazing. As with most big installs on a frame up build you have a bit of hesitation. All the questions are being answered, concerns are being addressed, and even some suggestions are given to get exactly what I need to finish this part of the build. And the response time and availability of the support staff is tremendous. Highly recommend The DuffTuff guys and their products.

My original review belongs here – this is the actual kit I installed and went tie rod over. Unquestionably the single most significant upgrade I’ve made to improve driveability, eliminate bump steer, and address my twitchy steering. Couple this system with good ball joints, a solid steering box, and a proper alignment to really get results. Fully adjustable system, beefy, rock solid. Best thing I’ve done, hands down!
