Its long,....

OK before you run out and get QA1 billet 12 point adjustable shocks I discovered some minor problems with the install.

I bought stocker stars for the rear of my truck for full adjustability.
1) the eyelet sleeves they include in the kit need to be honed out to (9/16 or 14mm) to fit stock shock bolts.
and the F*ckers only included 1 in the kit. You obviously need 2,per shock. I guess you could dig out the sleeve on your stock shocks but I just went to Ace hardware and bought some.
2) you need to come up with 3/8,thick space to equal the same width as the eyelet on the stock shocks. The qa1's are alot narrower. I used 1/8 thick Stainless washers on either side.
3) the way the shocks are designed you need to grind alittle bit of the lower shock mount on our axle so the shock"body" doesn't rub. I guess you don't have to but the thought of the billet shock body rubbing on the axle bracket doesn't sit well with me.

If any are interested I have the p# and price were I got them.
I have 4" hotchkis, if your any lower you'll need shorter shocks than the ones I found.
specs;
p# HAL-TC1539P
Thunder Racing sells them and you can get them from QA1 direct for alot more than retail stores. I choose summit because I had credit there, but I'm sure Thunder would give you a good deal.

Compressed- 15"
Extended-24"
driving height should be good for 18"-What my Bilstiens rode at.

o= setting very soft
12th setting = M1 Tank.

again, you need to buy at the hardware store, 8-9/16 heavy washers(approx 1/8 thick) to go on either side of shock eyelets. Also the kit only inludes 1 (1/2") sleeve per shock and 2 5/8 sleeves.

you have the option of getting 2 more 1/2 sleeves from Qa1 direct and drilling them all out for your 14mm bolts(9/16 same thing) or utilizing the 5/8 sleeves and upgrading the 4 shock bolts to (grade 8) 5/8 bolts. If you go the 5/8 route you'll need to drill out the factory shock brackets and also buy 8-5/8 heavy washers instead of 9/16.

I choose to get 2 more 1/2" spacers and use my drill press to drill them out to 9/16(14mm) and retain my factory shock bolts.
At zero it feels like a old Cadilac(to Me)Real soft.
At 5-6 it feels they way I like. Good overal ride
At 10 there stiff but still not as harsh as the Bilstiens, basically the "autocross" setting.
I didn't turn them to the full 12 because it seemed kinda pointless.
Overall, Truck is alot better for cruising now.

I got the part # for the additional sleeves you need if your keeping the stock bolts. P#9033-101

I Don't think two people can agree on ride but my truck is real light in the ass and I'm happy I now have adjustabilty.
Now I know why Airide Technologies uses these shocks.

I don't have the pics anymore in my computer but you can see them on my cardomain.

On either side of the shock just above the bolt hole took alittle over 1/16 off. Now that I have been driving it it was relly overkill but I didn't want the billet body of the shock getting damaged.

this is alittle off the Subject but I was looking at you CD page and I saw your console. Did you just get one out of a suburban or something? Any problems getting it to fit?

It's out of a LT 2000 ext cab.
It was almost 300 from the dealer but since 2000, the part #'s have changed and so has the availiblty.

I had a useless seat there before, It didn't fold down or offer any storage, (my truck is a base model) That unbolted and the new console bolted right up. No problems.

The only online place that might have some is
a non sponsor. I can pm you the link.
