What's the best 5/7 drop set up?
 

Hows it going! I'm new to the forum and I have 1977 silverado SWB. I want to lower the truck, but I'm not sure what set up to go with. I have seen the old set up with spindles and drop springs in the front, then hangers, shackles, and a flip kit in rear. But now they have lowering control arms and lowering leaf springs....I later want to put some 20''s - 20 x 8.5 front and 20 x 10 in rear...ANY SUGGESTIONS? Thanks

i prefure drop lower control arms and springs, they dont push the wheels out towards the fenders like spindles do.

Re: What's the best 5/7 drop set up?
 

if you do drop lower control arms do you have to change the stock upper control arm?

Re: What's the best 5/7 drop set up?
 

It's just a matter of personal preference on how you go about it. If it were me, I would look at the Summit Racing website and get your credit card out. Buy a set of DJM 3" spindles, and Summit brand 2" springs. For the rear I would use a DJM or Summit brand flip kit.

BTW- Did you just buy this truck? I saw one that looked just like it on Craigslist about a month ago.

you can use them with factory uppers.

Front:
3" Belltech Spindles
3" Summit brand drop springs.

Rear:
Flip kit
Rear Shackle
Bolt in c-notch


Drop shocks and a sway bar up front with good bushings.

Thanks for your advice, yes I saw it a month and ahalf ago. The previous owner and I talk, but nothing happen. So about a week ago, I called him and he made me an offer I couldn't pass up. 1977 chevy silverado trailering special with 59,000 orignal miles. It has a few mods, but nothing out of the ordinary.
Man, I have followed N2TRUX ever since you came out in classic trucks magazine...Your 77 has been my inspiration....thanks N2TRux is one of the best looking trucks I have ever seen!

Re: What's the best 5/7 drop set up?
 

Thanks for the info, so then if I get a flip kit I need to get the shackles and hangers as well. or just the shackles.

Re: What's the best 5/7 drop set up?
 

The flip kit will get you a 5"-6" rear drop.
The longer rear shackle will lower the rear an additional 1"-2", (since there are two sets of holes).

The "shackle hannger" kit is for people that only want to lower the rear 4".

If you combine the "shackle hanger" kit WITH the flip kit,... you will end up with approximatel a 10" rear drop. TOO much.
It can be done,... but you'll be cutting the bed floor and adding a Step notch to your frame. I don't think you'll get the front low enough to match the 10" drop.

Look around in the suspension section.
I think a 5"/7" drop is perfect on these trucks.
If you get them too low up front you will need to pull your inner fenders.
Also,... what are your plans for wheels? Those 8" ralleys may need to be swapped out (to a 6.5" or 7" ralley wheel) up front,... if you get too low.

Re: What's the best 5/7 drop set up?
 

This.

Don't skimp on front end service parts either. Fresh ball joints, tie rods, and a-arm bushings will make a big difference in how the truck drives and rides after you drop it. I know you said the truck is a low-miles survivor but it is 30-something years old.

I had a truck dropped with control arms and drop springs - it was a complete Chisolm suspension package (upper and lower arms, springs, drop rear leaf springs and shocks). The complete kit was crazy expensive but it was really easy to install and the finished truck rode and drove sweet.

Really don't want to spend that kinda money again, next time I'll probably go with spindles / springs / flip and see how that goes.

If i where you i would look into the Eibach systems...... they are a little more expensive then all the summit and belltech equipment..... but the eibach warranty is better than all(1million mile warranty.......cant go wrong with that)

Re: What's the best 5/7 drop set up?
 

That is a really nice truck. You might also check with CPP Jeff in the suspension forum. He can set you up with lowering parts as well.

Re: What's the best 5/7 drop set up?
 

That's a nice looking truck 77trailering. Welcome to the boards. Looking forward to the progress on your already good looking truck.

Re: What's the best 5/7 drop set up?
 

I thought that was the one. He had it posted at a really good price. If you get it below that you scored big.

Thanks for the kind words regarding my truck.

Re: What's the best 5/7 drop set up?

Re: What's the best 5/7 drop set up?
 

OK, your awesome, thats what I'm going to do. I will go with the spindles and springs. then in the rear with flip kit and shackles..thanks again.
On the wheels I am planning to go with some 20's 20x8.5 front and 20x10 rear. but wheels are going to have to wait....you know what a mean..lol

Re: What's the best 5/7 drop set up?
 

Thanks, I will look into it, but as of right now I think I will most likely end up going with the spindle and springs set.

Re: What's the best 5/7 drop set up?
 

I did and I actually called up there and they're sending me a new catalog. thanks

Re: What's the best 5/7 drop set up?
 

I just order the entire brake system pads,shoes,drums,rotors,brake lines,hardware,and wheel cylinders....Ouch!!! My next order is the entire suspension inners, outers, pitman, etc....... Definitely a bigger Ouch!!!!

Re: What's the best 5/7 drop set up?
 

I saw your thread, WOW, your living my dream....But I will get there slowly but surely....

Re: What's the best 5/7 drop set up?
 

Thanks, I called McGaughys turns out they only do 4/6 drop....So I will probably go with summit beltec....

Re: What's the best 5/7 drop set up?
 

Yup, it starts out a 4/6 but with a trim of the springs and move up of the hangers it sits low, and rides great!
