Description of πΏ RS8128 Leaf Spring Center Bolt by Rancho"
Diameter is 5 inches in length. Leaf Spring Center Pin Type is 5/16 of an inch. Kits are tailored to your specific application. For Front Axle Leaf Spring Packs. Centers the Multi-Spring Packs On Axle. 3/8-in. diameter x 5-in. long leaf center bolt.
I gave 4 tries because the screw head is too small. Most 3/8" center screws have a 9/16" head, but they only have a 1/2" head. Instead, I had to buy Rubicon Express 3/8 center screws, which have a 9/16 head.
Bolts worked as advertised. Use a vise on each side of the old bolt to hold the leaf springs in place as you remove the old bolt. Insert a new screw, tighten the nut, remove the vice and you're done.
I bought a pair of used heavy duty country leaf springs for my '99 XJ and the center pins needed to be replaced before I could install them. They matched the leaf springs perfectly and didn't have to modify the spring brackets on the rear of my Chrysler 8.25. Highly recommended!
The heads on these bolts are too small for a 2009 Ford F-150. The screws went through the leaf spring mounting holes. I welded thick washers to the shank of the bolt to prevent the mounting holes from going through. The original bolts have been there for 10 years, the replacement bolts were nice and long and made it easy to start assembling the springs.
