Small drops on 3/4 - 1 tons? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

w00dst0ck · 10-10-2017, 02:13 PM

Wanting to do a small drop on my 3+3. The only threads I'm finding are 5/7-6/8 etc.

Anyone have a smaller drop with some insight on how it rides? Also whats a decent setup to go with?

I don't want to have to cut the bed, remove inner fenders or c notch the frame.

**mongocanfly** · 10-10-2017, 02:54 PM

yep...I looked into dropping my c30 once but I didn't want to much...all the stuff I found is like you described. ..the easiest way to do a small drop would be start cutting coils on the front and pulling leaves out back...and best of all its free..except for your labor...
I think the smallest drop spindle I could find was 3"...I was looking for 2" drop

w00dst0ck · 10-10-2017, 03:35 PM

Yeah. I was honestly looking for a 2.5. My c30 has a 12v cummins, so the front end is already somewhat low.

I don't really want to cut springs or pull leafs.

I'm thinking of just doing the 3" drop spindles and Western Chassis makes a 4" drop leaf pack, I'm just wondering if their leafs are still stiff enough to haul with.

I already have both bagged and static dropped trucks, and I really want to keep the nice smooth ride that this one has for a DD.

Look over in the suspension forums. One of the vendors has a heavy duty link kit for the rear that uses airbags and you can install it to run at stock height. I'm going to do this to my dually as soon as I get a couple other projects cleared out.

That is what I was going to suggest. Some day I would like to run air ride all the way around on my K30 just for the ride quality.

I really don't want another bagged truck at the moment. Plus, that kit looks like $3-4k

There has to be a relatively inexpensive and good setup for around ~800-1k

Looks like $3-4K, but it is not. It is $1500.

Western Chassis 2.5" Drop Spindles for C20. . . $399 (have seen them for less.)
https://www.performanceonline.com/71...e-2-half-inch/

Add some lowering shackles in the back. . . you have a package for around $500.

c20/30's share the same balljoints and tie rod ends?

w00dst0ck · 10-12-2017, 07:52 PM

It's linked near the top. POL. Not sure who actually makes them though.

Just noticed that the 3/4 ton and 1 ton spindles are different, so that 2.5" probably wouldn't work. I still need to measure, just worried that 3" with this heavy motor is going to be too much.

I'll do more research but never saw different spindles for the 20/30. BJ are the same. Don't know about tie rods though.

Found this. 2.5/4 drop.

Did the c30's come with both 1" and 1.25" rotors. It's asking if it's an HD or LD.

wahl4m · 10-14-2017, 07:56 AM

that kit is neat -probably do it on my 39 international school bus ! would rather have a air kit for better ride ?? BUT ?? the kit is priced right !!if anybody has installed one ?please post some info on it !! thanks mike

Matt Man · 10-14-2017, 12:40 PM

This was my 86 dually, had western chassis 3" drop spindles in the front and some leafs springs removed in the back and drop shackles which was about a 4" drop. So 3/4 drop.

3/4 ton 88-98 OBS style trucks came in 2 versions (LD=6-lug; HD=8-lug).
1-ton trucks are all HD 8-lug set-ups.

The spindles shown in that ad are for '99 & later style trucks (exceptions are the 3/4 & 1-ton CC's since they remained OBS).

These are the 'kits' for square body trucks:

SCOTI · 10-14-2017, 01:49 PM

Well, the web site add when you copy/paste it is not correct.

They offer 2/4; 3/5; 5/7; & 6/8 drops for square body trucks. The 2/4 would be using front drop springs. The 3/5 through 6/8 utilize their spindles which are 3" drop or the spindles & a drop spring combo.

If you just want a small drop, try smaller tires on the stock rims.
