Double adjustable shocks

Who has the best price on double adjustable front shocks, I'm looking at something like QA1 or Viking for the front of my 71 Chevelle. The car runs mid 10's and I'm looking at spraying a small plate on the car next summer.

Re: Double adjustable shocks

It is my understanding, so take it for what it's worth....QA-1 staff started Viking, QA-1 is deemed marginal, Viking has had no complaints, but has not risen to the status of the bigger companies, but seem to be good value with support. Then you start to climb the tree higher, AFCO, Santhuff, etc. There is Chris Bell at Kinetics, and Mark Menscer motor sports for custom applications, they will also sell you the basic shocks. To me rear shocks are very important, and may be more important. I went with the custom shock advice from Mark Menscer to be able to re valve if necessary, and individual application settings.

Re: Double adjustable shocks

Mike pretty much hit the nail on the head. I can tell you the adjustment on the double adjustable AFCO’s on the rear of my car are absolutely required for my car to get down the track.

I run QA1 R series on the front. So far they have been “good enough”. I honestly use them more for tuning for weather conditions to keep the car off the bumper.

Re: Double adjustable shocks

The car currently has QA1 single adjustable rears with OG competition engineering fronts, stock style suspension set up front and rear. If I could only afford one pair of double adjustables would it be more beneficial to add them to the front or rear.

Re: Double adjustable shocks

I put DA ViKings on the back of my wife's car. Pretty happy with the valving. Eventually I will put ViKing struts on the front of it.


If i had to choose Qa1 or Viking on the front of my car, I would go Viking.

Take it for what it's worth, but my opinion is that a rear double adjustable shock is more important in the rear of the car. The ability to adjust compression and extension independently is very useful in the rear of the car. Most of what I do on my car is rear shock adjustment.

Re: Double adjustable shocks

Thanks Rick, my plan was to change shocks and possibly switch out the Moog front springs for a pair of Santhuffs.

Re: Double adjustable shocks

Its a 'spend it once deal' for sure. I went from Moroso 90/10 and 50/50s to out of the box AFCO fronts and custom Mencers for the rear. Then ended up needing Mencers up front to control the extension

Re: Double adjustable shocks

I had Viking DA Shocks on the Rear, with Moog Stock Replacement Springs & Air Bags, of my 67 and they worked okay

Also had the Viking DA Shocks/Coil Overs on the Front but they did not work as good
as I did not do the Extension on the Top of them
good for Cruzin the Hwy & Streets but I was unable to get them Tuned enough to get the Frontend off the Ground

Here is a Pic of my Car on Launch with the DA Vikings and 10 lbs of Air in the Rear Passenger Air Bag & 5 lbs in the Driverside



I then changed the Front Suspension to Old School with Moroso Trick Springs / Comp Eng 3 Way Shocks Set at 80/20
and the Rear Suspension I only Replaced the Viking DA Shocks with Comp Eng 3 Way Shocks Set at 50/50

Here is a Pic of my Car on Launch with those changes and NO Air in the Air Bags and which Resulted in my New Best Time



Note that I need to put some Air in the Rear Passenger Air Bag to keep it from Squatting and therefore getting air under both Front Tires

Re: Double adjustable shocks

UMI has 10% off right now till new years....I have the Viking DA shocks on the front and stock cheapie gas shocks on the rear. Been in the 10's with this setup as long as prep was decent. Probably should step up to adjustables for the rear at some point, just haven't needed to yet.

Using stock control arms in the front with moog 5230 springs, it is pretty difficult to install the shocks and adjust them....though I've only had to adjust them once...

I've heard this at the track too. The amount of adjustability and options for valving get me a bit nervous about doing doubles in the back. I run a 275 60 15 at the dragstrip and a 295 45 18 for road courses (and street). I got it figured out (or think I do) with Strange single adjustables in the back. I run them on the stiff side with the 15s and stiffen them up more for the dragstrip. I run them on the soft side for daily driving with the 18s and stiffen them up for road courses. I'm not sure I'd get enough runs in to figure out separate compression/rebound settings (especially with all the variability in the driver's seat). Also, DA shock valving seems like it might be specific to drag/road course applications.

Curious if DA shock users could share your reasoning for changes you've made to each setting.

PS. Love watching 'Honk' take off the line!

Ramey @ UMI is good people. UMI sell's Viking Shocks, likely more than the competition does. UMI after sales service is pretty darned good in my experience.

Adjusting for track conditions, for me its mainly how much rear separation is needed and how fast you want to control the front end. We usually adjust extension and leave compression alone.
