S10 Coil Springs?

Postby n8thenetninja » Fri Feb 24, 2017 6:16 am

Hello, I know that a lot of the front suspension parts from the S10 fit the H-Body, but what about the front coil springs? I'm doing an aluminum LS1 swap into a Vega and wondering if I could use the 4.3l S10 springs, since the iron V6 is probably about the same weight as the aluminum V8.

Thanks for the help!

Don't forget that S10s have a full frame, while the Vega is a unibody. Just a quick look at the specs, though - while the springs may have similar load ratings, the S10 springs are at a 10.75" compressed height compared to the Vega's 9.00". Plus, the S10's spring rate is in the 500 lb/in range, compared to the Vega's 300s. An LS is probably closer in weight to the stock 4 cylinder engine instead of an all-iron V6. Jeff Schwartz used the stock Vega springs in the Flyin' Turd with an all-aluminum 5.3L LS.

I think Chuck is pretty close to spot on there, the Sonoma is 3600/3800 pounds to the Vega's low, low 2000#'s range depending on vintage, So I would expect a rate difference of that much for sure, with a shortish search you should be able to find exact rate depending on year and options on the S10/S15/Sonoma. You may get a pretty stiff spring from an early short box regular cab 4 cyl. stripper, but installed height will probably be the stumbling block as Chuck points out! :th: Harry

I apparently need to check my spam settings or something cause I didn't see any emails when your responses came in. Lol

Thanks for all the info! I hadn't considered that the LS and the l4 might actually weigh about the same. I am putting a TH400 behind it though, so that might make it dip a little lower. I guess the smart thing to do would be to see how it sits with the stock springs and go from there. I'll post results whenever I get that far.

Is there any such thing as "V8 springs" available for the Vega?

Those might be just what you need. IF they exist . . .

The Vega is so much lighter than the Monza that the closest spring to being right for an iron V8 Vega is one for a V6 Monza. Also, the early Vega will require an upgrade to "deep pocket" Monza or later Vega style lower control arms.
The "fleet"-
77 Vega Estate wagon- project(someday)will have TPI305/T-5, S-10 spindles/axles
72 Vega HB Drag Car -383/'Glide/9"(9.35@146.19)(5.94@117.28 1/8th)
76 Vega GT- 400/4spd/9" retired from active duty(rusty)
03 Silverado 2WD ex.cab (work truck/parts hauler)
04 Silverado 2WD ex.cab (retired)
06 Haulin' 20ft enclosed car transporter
93 Suburban- 350/4L60(retired)
00 Saturn SW2- wife's car
01 Saturn SC2- younger son's project
00 Saturn SL2- daughter's car
98 Saturn SW2- spare
and 3 more Saturn "parts cars"
Note- the very act of listing all of these has made me realize I have some kind of problem.....
