If the tooth counts are 12 and 41, that's a 3:42 (opt GU6), which matches the part number 1235128. 42/12=3.5, which isn't a common ratio. "9 88" should be the date code.3.42 maybe? "1235128 12 42 9 88" is stamped on both ring gears.
I think you can cut all of the second list except for $50.00 u bolts, and you might be able drop the $33 eye bushing in the first list. I would think the new Skyjackers will come with plan Jane poly bushings in black.got the quote back from ORD.
I think all of these parts are "required", correct?
- $460 - 2" Front Skyjacker Springs '73-'87(91) GM, pair
- $33 - Main Eye Spring Bushing Kit for Superlift/Skyjacker Front Springs
- $225 - Shackle flip kit, 2-1/2" lift
- $220 - (pair) Bilstein 5125 shock, 8.13" travel
- $220 - (pair) Bilstein 5125 shock, 10" travel
Which of these parts are "required" or "should have" or "nice to have"?
- $120 - Heavy Duty Front Shackle Kit, Greasable - Kevlar
- $200 - 4-1/2" HD Rear Super Shackles with Greasable Rear Spring Bushing Kit, 1-1/2" Spring Eyes
- $50 - Ubolt kit
- $99 - 1/2 T Ubolt Reverse Kit for 3" Axle Tube, 10-1/2" UBolts
- $112 - Vehicle brakeline kit
- $115 - Sway bar Correction and Disconnect System
ORD charges shipping no matter how much is spent, right? (shipping would be $250)

I questioned that $33 as well, I thought skyjackers came with bushings already in them.I think you can cut all of the second list except for $50.00 u bolts, and you might be able drop the $33 eye bushing in the first list.

going to need to set pinion angle 98% sure . . . and use steel shims NOT aluminum .You won’t need brake lines at 2”…..
Rear shackles aren’t a “must” but if yours are rough the ORD ones are nice.
If you’re only do a shackle flip on the rear you won’t need rear u bolts
Good point….on a truck I didn’t need to at only 2.5” but on a blazer it might be needed. Personally it wouldn’t hurt to have u bolts on had….not something you can easily grab on a weekend.going to need to set pinion angle 98% sure . . . and use steel shims NOT aluminum .
and when did ord drop tuff country springs ?
i like tuff country or BDS for soft ride .
short wheel base of blazers = the most needed work with smallest lift height change .Good point….on a truck I didn’t need to at only 2.5” but on a blazer it might be needed. Personally it wouldn’t hurt to have u bolts on had….not something you can easily grab on a weekend.
If you end up swapping out the springs and shocks for good ones later, that $600 got you some U-bolts and a lot of work. Yes, it will make the truck sit higher and if all you want to do is look at it, that's fine. We're just telling you from experience that using the vehicle is much more enjoyable with a suspension that moves. 22+ years ago I fell for the cheap RC price tag and eventually had to accept the fact it was way too stiff no matter what shocks I tried and yanked it back off to pay for Tuff Country (which was a big improvement). Years later, when I found myself falling behind IFS trucks on 2-track roads, I paid a 3rd time for custom springs, which overall has been one of the most enjoyable upgrades.Both are a lot more than $600.
That is what I was thinking. For only 2" of lift there are lower price options like lift blocks, ORD Zero Rates, longer shackles. The only pain in the @SS will be replacing factory bushings. Those things can be a bear to remove. I burned mine out with a propane torch.We haven't even really touched on the super cheap options that are available when you only need 2" of lift.
For example, you could get 1" EZ-inch (tapered?), and 6" shackles up front. In the back, you could do a 2" block. This will probably be noticeably lower, since your factory springs are probably at something like -1" lift now.
