You wanted the best shocks on your drag car and you've got them. Let's talk about
adjusting them.
(Music)
I'm Steve here at QA1 with Tim Anderson our shock tuning expert
and we're going to talk about the MOD Series Shocks today and the
functionality of how we make our adjustments for
different scenarios say on the front of a car. Right so on
the front of a drag car you get scenarios where the front end's
coming up too fast and too fast the wheels come off the
ground and you're you want to tame that down.
So taming down a wheel stand you want to start dialing up your rebound
so there are two rebound adjustments on this shock. There is the
high-speed adjustment knob and the allen small head screw next to it will be your
low-speed uh bleed adjustment. So on the high-speed
is what we would more consider like the
main adjustment? Correct. And then the low speed that you refer to that's more of
like what like a fine-tuning? Yeah fine-tuning and just
the slower shock movements of the front end. Okay. So
initially you want to slow that movement down so i suggest
dialing up the low-speed to a firm setting right off the bat when you're
trying to tame that wheel stand and then work your
high-speed adjustment. And the low-speed is uh
just with the allen head there right right next to the knob.
Okay. Now on the compression side of things
whether this is still the front end or the rear end how
would that be adjusted the same with a main adjustment and a
low-speed bleed? Yes. Okay. So the compression adjustment uh that's going
to be when your front end sets back down. So the initial launch and your front
end wants to come back down you know a little ways down the track
you know if it's coming down too hard it can unload the rear tires and break them
loose so you want to have that dialed up to a setting where
the front end is going to come down nice and smooth
and not upset the chassis. Okay so again Tim
on the front adjustments how how many clicks would you would you go per
adjustment? I would say you'd want to go at least two to three clicks to see a
noticeable change on the uh you know two to three clicks
on the high-speed adjustments and about a half a turn to a turn on the
low-speed bleed adjustment. And then see what you've got from there and uh
and then make final adjustments? Yes. So when we talk about the rear of a drag
car and our MOD Series Shocks are we still
adjusting the low-speed bleed first the
the high-speed how are we doing that? On the rear of a drag car I
recommend adjusting both simultaneously. So if you need a
little bit more rebound tune your high-speed adjustment up two
to three clicks as well as your bleed adjustment at the
same time. That's going to keep a nice dyno curve
consistent dyno curve through your adjustment range uh
generally I go the two to three clicks on the knob
and about a half a turn on the on the bleed adjustment.
Okay so and when we find ourselves in the extreme ends of
this valve pack that comes with the MOD Series Shock which is a very wide range
but there will be some cars that may find
themselves needing a firmer compression or a lighter rebound or
whatever the case is. How do we go about changing and going
to QA1's softer valve packs or firmer valve packs?
So we do have uh four different valve packs. We have
soft medium firm and extra firm uh we do have quite a few drag cars
successful ones that are running firm and extra firm valve packs.
So depending on your power suspension design
uh weight of the vehicle you know that is a scenario where you may need to have
that extra firm valve pack to control all that
all that energy uh and it's just uh as simply as removing these five screws in
the module just on the outside of the knob
here and it just pops out and then you can
replace it with your desired valve pack needed. And
because you've got MOD Series on your car you can change that on the
car in between rounds. Crazy stuff.
Well we hope you learned a lot here about your MOD Series for drag racing. If
you do have any calls give us a call at the tech line
