Post rear shock angle

I'm laying underneath my 47 chevy sedan delivery,I'm going to use chassis engineering rear springs,going to make my own mounts for the springs,shocks,my question is should I mount my shocks straight up and down, or tilt in alittle at top or tilt alittle back or foward.Or does it really matter that much?

I'll stick my neck out on this. Since you are using CE stuff you probably have leaf springs. You first want to determine what type ends you want on your shock. I prefer to lean my shock inboard a small amount and I prefer the eye type shocks. In this case you can not have two way tilt or you will have binding and severe wear in you bushings. I affix my lower bolt 90 degrees to the axle and the top bolt in enough to give me a maximum of 15 degrees angle at ride height. The top bolt must be parallel to the lower bolt. If you use eye/stud combination, then I mount my stud plate such that it is perpendicular to the stud at ride height and will not use more than 10 degrees angle, and the eye will be on the bottom. Regardless of what you use, you do not want a double angle; ie, tilt in and back. After all of this, straight up and down works and is easiest installation in some cases.

Jusrt read a piece in a magazine somewhere that the late model one shock forward/one shock back under most modern vehicles doesn't really do what they wanted it to do, whatever that was? But, the factories are set up to do it that way and so it remains. So.....straight up and down with proper extended and compressed clearances is just as good as leaning forward, or leaning inward. As the Treeman says, don't combine leans!

Its just a simple matter of geometry. With a straight axle, if you lean the shock any direction but straight up an down, you are diminishing the amount of piston travel and therefore reducing the dampening affect. The most effective is to have the shock straight up and down.

Sometimes you see the shocks leaned toward the center of the car from the axle attachment. This is usually done on swing axles to compensate for the fact that the axle angle decreases the natural 90 degree angle between the axle and shock as the axle lifts relative to the frame under cornering. This reduces the effective angle developed in cornering so that the shock remains straight up and down in the corner.

Short answer

Yup..keep the shocks as straight up and outboard as possible...Works better that way...
