hehe these things should help me launch. Now all I have to do is figure out where to set each ****

I am going out to play around with them, will let you know how I like them later tonight

 

Compression and rebound? Easy on the compression and tight on the rebound should help the launch.

 

Please tell more.

Why these Vs QA1 ?

Price Differences ?

That is a adjustment for both dampening and rebound right ?

Sorry for all the questions, Thanks

 

Regarding adjustable shock settings:
This issue seems to have oppositional opinions. With some people saying set shocks soft in rear and stiff in front, or stiff in rear and soft in front.

Most people seem to be saying soft in rear........however...........

if you set soft in rear you can waste energy lowering the bed of the truck rather than pushing downward on the tires.

Some claim that weight transfer from the soft rear shock setting will get u better traction by the physical body weight shifting to the rear..................but

aren't you just transferring weight that would have been on the tire onto the bed.

Squat is good when it's the suspension squatting, but if it's just the body of the truck that is squatting, are you really achieving better traction?

PS . those look nice Don.

 

Hey Don, those shocks look like nice units, let us know how they feel after you get them tuned in. Maybe you can come down to Cecil on April 17th which is a SSOTN meet (closed event) and try them out, later, John H.

 

Huh The weight of the truck will only be "felt" in four places - each one of the tires. I think that the idea is move weight from the front tires to the back ones - thereby yielding more friction on the slicks. Friction is just a product of the coefficient of friction and the force normal.

Steve the extra weight transfer is what will plat the tires to give you a better short times. One way you could say that you would have wasted energy is if the truck was to lift the frontend more than it carried it forward. Another way is when you transfer so much energy into squatting the rear that it bounces back. This is a advantage to a double adjustible shock, you can not only set how soft is compresses but you can set how hard it rebounds. These shocks offer you the best way to find the best of both worlds. If you look at a proper set up suspension on a drag car, the car will shoot forward, those cars you see doing huge wheel stands are the guys waisting energy.

Hope that helps

Having said that, do I not want squat (sounds funny)? I don't see pro stocks and funny cars squatting. My question being, doesn't a stiff rear setting actually transfer more to the suspension and tires, and not just loss of energy by making the body of the truck squat in the rear?

 

O/T but I just got a set of Penske double adjustable cannister shocks for my race car. Before we only had adjustment on the rebound but now we will have full control over the shock without having to rebuild as often as before. Hope they work for you.

I have a set of Afco gas shocks that we ran on my car last year. If i valved them right what length would they need to be for them to work on my L?

 

BigFan's explination is pretty much dead on

My first impressions are very good, right now I have the set softer than the QA1's but with quicker rebound. It is a differnt feeling the rear leans into the corners a little more, but it feels like the tires are getting better traction. In a straight line it feels like it is getting better traction too.

I have them set at 5 and 3 right now, I am going to try 6 and 3 tomorow and ride that way all day. Saturday I am going to try 6 and 4 to see how that feels. I want to get a full day on each different setting so I can get a true feeling. Also my new 70/30 QA1's for the front aren't here yet, so untill I get those it will be hard to totally set up my suspension.

As for the price, they aren't cheep in the $650 range a pair. I will talk to Jim at JDM and see if I can give out the guys name I got them from. I think I owe it to Jim since he is the one who gave me the contact info. I know Jim has been working with him, and I actually got mine before Jim.

I am pretty sure I am the first set to be installed on a Lightning, and there was a issue with the top mount. Lucky for me the heime joint kit I got from stan uses the same threads as these new shocks. I talked to the company selling them, and they will be taking care of this issue.

I have to also talk to Doug and if Jim gives me the OK we might be able to get a group buy setup.

 

Also I mentioned the new QA1's on the front, I might have a new model/option for the front of our truck soon. I am working with a different company on those. I am getting a custom made front set, that will be a inch taller when fully compressed, and two inches longer at full extension. These are being made by taking parts of 3 different QA1 shocks and combining them to make something better for our trucks.

One interesting change I am having him do, is take the top threaded shaft from a GM kit so I can use thicker Energy Suspension shock bushings. The inch longer top theads will make this possible.

These are something I will be able to pass the info to anyone, as I did all the leg work. If there is enough interest on these, he is willing to do a group buy for us.

I will fill you all in on the fronts after FFW in Orlando.

P.S.

I will get those springs out tomorow it has been a crazy week.
