Eric... on a single adjustable shock is the control
valve controlling JUST the extension or does it also
control the compression.... I have a old set of QA-1s
and was told it is only controlling the extension
but they are old.... now I hear a lot of shocks are
controlling both on a single adjustable shock





also on afco shocks that have the single adjustment "window" where you move the adjustment side to side. is this only adjusting extension?

what would be any advantage of replacing the "window" shock with a new double adjustable?

thanks for coming aboard



Great questions....on AFCO shocks, the adjustment on the end of the shaft controls the rebound...specifically, the first generation shock had a window that did that job. Counter clockwise (when looking down at the end of shock) made the shock stiffer.....

There are shocks out there that one knob controls both compression and rebound. The philosophy of each company is expressed here in their design...Each company has their beliefs as to the benefits.

To the comparison between first generation and second generation AFCO shocks, there are some refinements.....Friction reduction internally to allow for improved movement, detents on the adjusters for positive adjustment and improved valving...When you gather on-board data and apply that info to the adjustment range, you end up with a shock more closely matched for the application....
