Anybody heard of McGaughys Suspension?

[Gregski]

So I am looking for some 2" drop coils for the front of my '74 half ton. I know that LMC Truck has em for $150 plus shipping but they don't tell you the brand or any specs, I don't like that. So I go lookin' on eBay where I come across these McGaughys suspension coils. I am not affiliated with them nor peddling their stuff. I never heard of the outfit, so I am asking if anyone has?

Also what's interesting is that they want $110 for the GMC ones and $140 for the Chevy ones, same part number 33128 and free shipping, so sounds tempting

not even sure if this is their website http://www.mcgaughys-suspension.com/
they seem to be out of Phoenix Arizona

McGaughy's is a good product.
Look at other places besides eBay.
Summit racing usually has free shipping.
Or look at the board vendors on here.

thank you what would help me is knowing the specs of the stock springs, height, pre load, etc. and then knowing what the height of the 2" drop ones should be and the preload and spring rate

Good luck with that.
I would contact the spring manufacturer.
I think the answer will vary from brand to brand.

Not that it matters but, I believe the that ones LMC sells are McGaughys. It's been maybe 10 years or so since I bought some lowering stuff from them. I think the springs were McGaughy and spindles I bought were Western. My memory could be a little dubious.

good idea, I just found these by DJM for $126 bucks and at least they look really nice but still no specs, no problem these guys have a website and are in Gardena California, I will drop them a line and see how friendly they is

I don't mind all this leg work I enjoy the learning process, I do not know much about suspension components (yet) hee hee

Call McGaughy's or Bell Tech and talk to their tech lines. That being stated, I have dropped several trucks with both brands and have had no issues with either one. I did not ask about the preload, either.

Never ask an Engineer to do a Blacksmith's job and NEVER ever ask a Blacksmith to do an Engineer's job. The Blacksmith will build it, the engineer will calculate it's failure rate.

These guys usually have good prices on McGaughy's stuff.
And great customer service,...

got an email back from DJM and not sure if the guy is being funny or what, but this is what he sent me when I asked him for the specs on the front coil springs

"They are 10.48676465% stiffer than stock"

Here is what I got from Classic Industries Tech Support when I asked them about their stock replacement coil springs, I am rather impressed

The specs are as follows

6452

3.68 inside diameter
0.781 bar diameter
843 spring rate
3155 load
10 install height
13.64 free standing height

Those springs from Classic are Moog springs. $99.99 + overweight shipping.

Summit Racing has the same exact springs for $76.97 (with free shipping on orders over $100.00). They are stock height springs, not drop springs. http://www.summitracing.com/parts/mog-6452

Here are some of the stock spring numbers and their ratings. I think if was Rob in the Make It Handle thread that listed these.


Spring rates for stock style C-10's seem high, but this is do to the A-arm ratio. Here are some stock spring rates

Moog # 6082 722 lbs/in 6 cyl, and light v-8
Moog # 6542 842 lbs/in std v-8
Moog # 6102 1015 lbs/in bigblock, longbed c.s.
Moog # 6104 1016 lbs/in 3/4 ton, sits 1/2" higher than #6102
Moog # 6454 1060 lbs/in 3/4t bbc, c.s, 1 ton

If you only want 1 1/2" or so drop, use the 6102 3/4 ton spring, and cut 1/2 a coil.

Also, Early Classic Enterprises makes some good springs and parts.

You can get custom coils made to your own specs by Valley Spring Works in Dixon CA. He will build them any way you want from custom drop to progressive rates.

I thought I read in a post on here that 1 full round cut off of a spring = 1 in not 1/2 round = 1 1/2 in?, but then again I am easily confused. BTW rockauto has the 6102 springs for 65.79 not sure on the shipping though.
