This may seem rather dumb but,
My 89 Bronco has quad shocks on the
When buying shocks for it most companies list
(A)##### (B)##### positions.
Which is which, is the A shock the front
B rear?

Is one shock longer than the other?
and if so which is which?

 

Usually they denote the one that is rear-most mounted. I believe they are valved differently. You don't have to run quad shocks, you can run singles in you want.

 

A and B corresponds to the length of them Which also would be front to back as as the rear ones are shorter than the fronts. What brand are you looking at? With quad shocks you just need 2 of each.

 

Already have Rough Country.
I didn't put them both on. When I got them I bought them for a 2.5 lift but when I put the spacer in it (A) didn't make as much differance as it did in my BII (B) one shock seamed to be way too long.

 

JUST ADDING MY 2CENTS i've been rebuilding my 91 f/s bronco and i'm only useing 1 shock towards frt.

 

I have looked at the listing in the LMC catalog for shocks because I have some questions also.

It appears that Quad shocks are part of a "HD" designation, and makes it appear that the spring rates between the Quad and Single shock vehicles is different.

Since I dont go flying over rock piles or dunes, I would like a little less spring rate in the front, but have no figures to play with. Years ago, I went through one of those "contests" with a factory rep over the van front springs. I was able to overcome the factory argument of "Equal to or better" quality OEM parts.

Somewhere (if it still exists) there is a small book that gives all kind of truck specs, including spring ratings with spring codes. Wonder If ND has seen or knows about the ratings---
