Extreme Duty Leaf Spring U-bolts | 78-79 Ford Bronco

Product Overview:

The force and stress placed on stock components during off-roading can be extreme, and we’ve seen firsthand how weak factory U-bolt plates just don’t hold up. After bending stock plates time and time again, we knew it was time for an upgrade. That’s why we designed our Extreme Duty U-Bolt Kit—built to take the abuse, handle rough terrain, and keep your rear axle secure no matter where the trail takes you.

Full description

Extreme Duty Leaf Spring U-Bolts Kit | 78-79 Ford Bronco

Upgrade your 78-79 Ford Bronco suspension with our Extreme Duty Leaf Spring U-Bolt Kit, built to handle the stress of off-roading and rock crawling. Stock U-bolts and plates just don’t cut it when pushing your rig to the limit—that’s why we designed this kit to be stronger, thicker, and more durable to keep your rear axle and springs mounted solid.

Why Choose Our Extreme Duty U-Bolt Kit?

Heavy-Duty Construction – Built with 5/8" thick steel plates (compared to the weaker 3/8" aftermarket options) for extreme durability.
Stronger U-Bolts – Upgraded from stock 1/2” U-bolts to Heavy Duty 5/8” U-bolts for superior strength and stability.
Precision Engineering – Unlike cheap flat plates that create rigid pressure points, our routered edges match stock contours to prevent spring breakage under articulation.
Corrosion-Resistant – Zinc-plated U-bolts and plates for long-lasting protection against rust and wear.
Trail-Tested – Designed for hardcore off-roaders and rock crawlers who demand maximum durability in extreme conditions.

Don’t settle for weak stock parts or inferior aftermarket options. Upgrade your 1978-79 Ford Bronco to Extreme Duty U-Bolts and hit the trail with confidence!

So I ordered a set of new leaf springs for my 1975 F100 4x4 and this kit was suggested at check out. U bolts are expensive and the price was right so I added to cart. when the parts arrived I was so impressed at how overkill the base plate is. The Zinc plating on all the parts is a nice touch, and the 5/8 U bolts allow more torque increasing seat pressure on the springs. this should cut down on U bolts and center pins getting loose while hard wheeling. I would definitely use this kit on future trucks.

These are definitely thicker u bolts vs stock, but they're actually 9/16", not 5/8". The plate is a solid 5/8" though.

This is great product you should be using if you're wheeling or crazing the streets. I've purchased two sets and will again for every Bronco I own.

Great Kit. Seriously strong and the correct width for Bronco springs. Super heavy duty plate. The only thing keeping 5 stars is the plate is not plated or panted. Looks like it is plated but 3 weeks later had surface rust. Remove and paint took care of it.
