Product Details

The Tuff Country 17758 rear axle U-bolt kit is specifically engineered for lifted 4WD trucks and SUVs equipped with 5.5-inch lift blocks. These heavy-duty U-bolts provide the extended length needed to properly secure leaf springs and axles on vehicles with suspension lifts.

Key Features:

  • Zinc-plated steel construction for superior corrosion resistance
  • 14-inch overall length designed for lifted applications
  • 5/8-inch thread diameter for secure clamping force
  • 3.5-inch inside width fits standard axle configurations
  • Round-style U-bolt design
  • Made in the USA with precision manufacturing

These replacement U-bolts are ideal for upgrading worn factory hardware or completing a suspension lift installation. The zinc plating ensures long-lasting durability even in harsh weather and off-road conditions. Compatible with most stock and aftermarket leaf spring systems on GM 3/4-ton trucks from the 1970s-1980s era.

I finally had time to install my part. The steering wheel hub was exactly what I needed at a great price and delivered promptly. Thanks for the great service.

I searched the internet high and low for the JKS Quicker Disconnects and almost thought it was a scam when I found them for this price! The order was simple and the shipping was fast. I could not be happier!

Great communication, super fast shipping, and product just as described. Very happy, thank you.

I found them doing a search for a clutch kit, they are hands down one of the easiest companys to work with and the prices cant be beat..... I looked everywhere

I would not hesitate buy from Autoplicity again!!! A+++

Autoplicity had the best price anywhere! I looked everywhere for the airaid intake system and they had it in stock. Great company!
