1958 Chevy Truck Total Cost Involved Leaf Spring Kit & Eaton Posi Install - Tri-Five Rear Slam & Rebuild For Under $2,000

The leaf-spring brackets install in the same location as the stock ones. It may be necessary to drill a few holes to align the brackets. Once in place, the leaf springs are installed.

The only welding required are the spring pads to the rearend housing. Spring pads are welded to the underside of the housing at a 3-degree pinion angle.

After that, the housing is installed to the leaf springs with the provided hardware.

The last Total Cost Involved mounting plates installed are the upper shock mount plates, mounted on the inboard side of the stock upper shock crossmember with three bolts. Once mounted, the shocks are then bolted to the upper and lower mounts.

All done. Here's the Total Cost Involved leaf spring kit setup completely installed...

...Simple, yet so efficient.

Now it's time to rebuild the rearend, in this case an affordable Chevy 8.2 10-bolt. Harry at Harrison's Restorations let's run down the parts that are going into this build. The Yukon Ring and Pinion (PN YG GM8.2-355) is a standard 8.2 3.55 gear ratio that is made of 8620 steel. We decided to go with some stout middle-of-the-road gears, which will be highway friendly as well as giving us just a little more bottom-end grunt.

We also ordered this Yukon Master Overhaul Kit for a '64-72 GM 8.2-inch 10-bolt. Included in this kit are carrier bearings and races, pinion bearings and races, pinion seal, complete shim kit, ring gear bolts, pinion nut, crush sleeve (if applicable), oil baffles, and slingers (if applicable), thread locking compound, marking compound with brush, and a rearend gasket.

Here is the Yukon 8.2-inch axle (PN YA G1255802-SH) we choose for the build. The new axles are 301/4-inches, with a 2.780-inch hub, and 28 spline count. On the left is the OE axle we pulled, and on the right is the new Yukon axle. Notice the Yukon axle hub is thicker, which makes them 20 - 25 percent stronger than OE.
