You. I like your philosophy. What you said made perfect sense after I read through my own posts. Couldn't find the forest for the trees so to speak. I had so much information ruling things out that I didn't realize, it was time to move on.

Cool...

Not sure if or when I'll make it to a Nats event, since I don't actually own a Sy or a Ty.....

Not even sure you guys would let a 2nd Gen Bravada join in the fun. But it does sound like fun.


That's the reason I like this board. It's personal. You guys are a tight knit group, help each other out, and really care about others. I also surf LS1Tech, and it's so big as to not be personal.

And you guys aren't afraid to modify your trucks with parts that sometimes are cobbled together in the garage, mostly because you can't just go out and buy what you need (doesn't exist). That's the kind of spirit I like. Not afraid to get your hands dirty, or think hard about something, or engineer a new solution (break out the dial calipers and CAD software).


Back to the thread at hand.....

I'm guessing that we're going to need small body shocks, something capable of using a 1 7/8" spring in order to have a chance at using the stock control arms.

Looking at QA1's offerings:
1.) The 82 series looks like it would work, is revalveable and is rebuildable, threaded alum body, can be run upsied down, and are available in a bunch of strokes (from 3" to 9")
2.) The 79 series could work. Steel body, available to do 1 7/8" coilovers, 5" amd 6 stroke. Not rebuilable, though.
3.) The 70 series might work, but they're only available in 6", 7", and 8" stroke, might be too long. Steel body, rebuildable and revalvable, can run upside down. Catalog doesn't specify what coilover size it allows, however, so if the stroke would fit, that'd be one more thing to check out.
4.) The 75 series would work. Steel body, available in 3, 4, 5, 5.5, 6, and 7" strokes. Not rebuildable or revalveable (except for rod end type bushings). Can run 1 7/8" springs, and can run upside down.

These are circle track shocks. They don't have knobs or anything like that for adjustment. I'm not certain how they'd fare on a street car / truck.

I think the thing that needs to be done at this point is figure out if any of these parts would be adequate. Basically, we need to do the engineering work to determine lengths (compressed, extended, ride height), angle of the shock (with respect to vertical), corner or front / rear weights, and motion ratios (which is the distance from control arm pivot to shock mount divided by distance from control arm pivot to center of tire contact patch, squared). This will allow us to get a good estimate for a recommended spring rate, and to figure out exactly what shocks will fit our needs (stroke, etc). At least, that's where I'd start.

I haven't touched it. Been busy with other stuff. Can't speak for anybody else.

i've researched shocks to an extent....tough finding small dia shocks that are meant for load ratings high enough for our trucks

Re: Can I use them like this if they fit ?

I am buying one of the qa1 shocks and 2.25 I.D. springs that mike uses in his front setup . After looking at my friends rpm front setup , I see what needs to be done .

I am o.k. with modifying my upper arm and reinforcing it . To me this is no different than the ls1 spindle mod . When it arrives I will be getting right on it .

woooho for the creative brains we have on this board!! low budget coilovers!!

Your gonna have to share the LS1 spindle mod too. You know that don't you? Finish this one first though.

modifying in what sense? would you have to cut it to fit the spring in, then reinforce the arm while working around the spring?

Re: Can I use them like this if they fit ?

I see 2 possible spots to modify . One for sure is opening up the insides of the upper arms , and then reinforcing it hopefully from the inside so it looks undercover . If that isnt enough to fit everything , I will have to move the lower arm shock mount to where it allows clearance .

Between the shocks , springs ,more por 15, paying the sand blaster and welder , I doubt I will have 600 into everything .

sweet, i cant wait until there is a write up on it, i will be one of the first to fork over for this! I can justify 600, not 1200. How ever I am sure the more expensive product is a great product.

Re: Can I use them like this if they fit ?

Just to note. JS Manufacturing tried some of the AFFCO shocks on one of thier proto type tubular suspension Syclone trucks (Darons I think?) and they failed miserable! After some where close to 3000 miles they were junk. AFFCO's are a great racing shock, in fact I use them on my super stock race car and I have them rebuilt regular. They aren't meant for Sy/Ty(heavy) applications. To fragile. I would stay away from them.

QA1 shocks are a great value but are not very consisent shock to shock. 4 clicks tight on one might be 6 clicks tight on another and 10 clicks on the next one. I have seen in person QA1's on a shock dyno and it ain't pretty. They are very durable though. I have used them in the past on my race car, but they drove me crazy trying to tune the chassis in.


Koni makes great coil over shocks. But they are $$$$$ and finding they correct one for this application as george has found out is doubtful.

Just my :2cents: . But this is a great thread. Keep the info coming!

Best bet might be just slightly relocating the lower shock mount. I think I may try konis. I need something that's gonna hold up. I drive my truck too much.

Re: Can I use them like this if they fit ?

That snot a bad idea . I will see if I can get away just modding only 1 of the 2 arms .

I really didnt think there would be a problem using the qa1's , since I would end up with them anyway if I plunked down the 1500 for either of the 2 companies kits . I did look into some other shocks , but for the money , the q's cant be beat . Also , the stock arm mods should be the same with konis , qa1 or (insert favorite here) given the shock and spring dimensions from one brand to another are close .

Re: Can I use them like this if they fit ?

Passenger side is done .All I need to do is make some spacers to hold the shock in place , and flip that bolt around .No touching anywhere during the full range of motion . Now to get my tune in order ....

Any part numbers available? Did you have to modify the stock arms at all? Thanks,

Thanks MRKING, this was very helpful,

personally, I'd rather support a vendor and get everything in one package for $100 more in total price.
