Rear Shock orientation - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Jemezcrusher · 09-26-2016, 09:03 PM

I put a TCI parabolic rear spring and shock set up in my 1950 3100. My rear is an 8.8 out of an Exploder. The rear shock crossmember is set up to go behind the rear end. The rear end has a nice sway bar that I planned on using but is going to interfere with the shock location.

Any reason I can't locate to crossmember in front of the rear end at a similar angle as it was supposed to be behind it?

No big horse power. 235 with dual carbs and split exhaust with a T5

Nope should work as long as you keep the working angle of shock at 25 degrees or less

I used a exploder rear also, and used the spring, shock and swaybar as original. Why do your leaf springs interfere with this?

No reason not to if it makes for having it work the way you need it to. There are a few factory setups with the shocks in front of the axle. I think Ford F 150s have the shocks angled forward in front of the axle with the brackets on the bottom side of the axle.
Stock AD shocks angled forward in front of the axle.

Shocks do not know if they are in front or back. With stock spring setup front to back will not significantly make any difference. If it was a 4 link or swing arm conversion there might be a difference in how fast the shock responds and recovers depending on the distance from the mounting point to the lever arm pivot point. If you google shock layout there are sites that show now much efficiency you lose as the angle from vertical increases.

I am just eyeballing the shock location it's the TCI mount and will hit the sway bar, not the spring

Just asking why use an aftermarket swaybar when it has one stock that fits? I used it and its endlinks, attached to frame.
Not my truck but explorer below for reference.

If I put the shock crossmember in the recommended location, the boy of the shock is against the bracket that holds the stock exploder sway bar. Seems pretty easy to just move it on the other side of the diff (shock cross member I think)
