Better than OEM!
"I needed these to compensate for the thicker HD leaf springs I installed on my Frontier. These were identical to the factory U=bolts but a little longer. There was no need to drill the U-bolts like some of the others U-bolts."

"I needed these to compensate for the thicker HD leaf springs I installed on my Frontier. These were identical to the factory U=bolts but a little longer. There was no need to drill the U-bolts like some of the others U-bolts."
"This was a great purchase. I was very pleased to find that each bolt was coated down to the beginning of the threads. The nuts were a sturdy set and threaded on easily. Torquing specs were incuded and matched my truck model's info. At first I thought I could 'get-away-with' not buying these seperate hardware items, but when the rear end came apart and the old U-bolts came off, it became obvious very quickly that the new springs deserved a fresh set of stabilizing hardware as well. Now the truck is up and running well and the rear end handles better than I could have hoped for. I couldn't be happier with this part of my total purchase from Ironman 4x4. Thanks guys!"
"I called, a knowledgeable sales representative answered the phone immediately, and gave me a part number for the bolts I needed. I ordered them, and they came in a very timely manner, and also included a hat, koozie, a few stickers, key chain, and a bottle opener. Bolts were exactly what I needed, and I enjoyed the extra swag from the company. Overall I had a very nice experience and will definitely be ordering again from them in the future. Awesome job."
IRONMAN 4X4 U-bolts are simply the best option for securing your leaf springs to your 4x4's axle!
