1979 Chevy Silverado - Father Knows Best - Tech

And finally, you'll remove the axle's C-clip and ultimately slide the axle out. The old brake backing plate will be your last obstacle before installing the new PST rear disc conversion package.

It's not a bad idea to replace the axle seals. They're not supplied, but easy to change, and you'll appreciate the peace of mind.

At this stage, it's just a matter of reassembly.

Your rear calipers feature a single 45mm piston and integral parking brake assembly. Once they're tightened to the mounting brackets, all that remains are your fluid lines.

Next it was time to tackle those old stock springs.

The U-bolts securing the springs to the rear axle will likely take the most muscle to remove. But a long 1/2-inch breaker bar and/or a length of pipe (for more leverage) should be all you need.

PST's 4-inch rear lowering springs feature less than half the amount of leaves (over stock) and are engineered with less arch.

Once you run the bolts back into the spring eyes, a little finesse is required to get the alignment pin properly seated in the spring mounting pad.

PST custom-tailors the proper lowering shocks for each application. Though we missed our photo op of the fronts being installed, the changeover is simple, no matter which end of the vehicle you're working on.
