Who Makes a Good Rear Coil Over Double Adj. Shock

I run QA1's and they work great. I think the following guy does too.



He has had some pretty good luck. Most of you know who it is. (a little hint 4.44 @ 175 with a 1.15 60' on a drag radial)

LOL, it can be damn easy to buy the wrong shock since sellers (Jeggs/Summit/etc) don't always give all the needed shock info in the adds. The first set of coil over shocks I ever bought many years ago were damn near useless "big sale over stock" Koni's from one of the big name "kit" chassis shops at the time. But they never mentioned that the cheap Koni's they were selling weren't the desired SPA1 shocks (with the drag racing valving profile). And at the time I didn't know any better, I thought all Koni's were the same.

The Alden business thinking has always been a mystery to me. They appear to have all the equipment & machinery to design/build coil over shocks, so why not design & make a second line of proper shocks just for drag racing that are non-Nitrogen charged? But then I guess that might be asking too much since after all these years they can't seem to come up with a seal design that doesn't loose the Nitrogen charge on the line of shocks they do make.

I love it when people ask me if i know my coilovers are on upside down....lol

X2 lol

The Afco shocks are damn interesting because of the fact that you can mount them upside down. Sure wish I had a junk Afco so I could take a look inside to see how they designed it. Two things you usually need for shock valving/dampening to work correctly (and offer resistance) is the piston & valve assemble(s) need to be/stay submerged in shock oil. This has me kinda thinking that either they might not have any of the valving assembly on the piston it's self, but maybe some kind of a valve port is drilled somewhere in the middle of the shock shaft. Or maybe the piston is it's self somehow mounted somewhere in the middle of the shock shaft (vs at the end of the shock shaft). Either way that could explain how the piston/valving can be submerged in oil when mounted either way.

When QA1 finally came out with their own double adjustable shock, the fact that they put both adjuster knobs at the bottom & side-by-side had me thinking they looked a lot like Chris Alston's Vari-shock design. I guess it could be that one company might have copied the other, or maybe it's collaboration between the two, or it could just be a coincidence.
