1963-1972 Chevy & GMC Dropped Rear Coil Springs Install

[@aaroncarranza1129]

Thanks for all the videos. Makes things alot easier knowing what I'm getting myself into before hand. Just a tip from the original service manual- there is a notch on the spring retainer cups that line up with the end of the coil. Book shows end of coil on bottom to inside and end of coil on top to the outside. I just lined mine up where it was the least binding.

[@BROTHERSTruckPartsTV]

You are correct! We seat them in the mounts where they feel "right" which is right in those pockets you mentioned.

[@donlewis1701]

David, Thank you for the detailed video. I am doing front and back drop 3 / 5 springs and shocks this weekend. wish me luck.

[@BROTHERSTruckPartsTV]

Easy job, you'll be fine!

[@BROTHERSTruckPartsTV]

BTW, check out our how to change front coil springs video too for extra help!

[@donlewis1701]

@@BROTHERSTruckPartsTV Did the rear springs this weekend . It took a lot of work to get the bolts off. But that should be expected for bolts that have been in for 48 years. PB Blaster is my friend. Suggestion to others lots of lube before the job. Feel good only broke 1 bolt .waiting on my shocks then can button up the job.

[@BROTHERSTruckPartsTV]

@@donlewis1701 Yeah Don, watch the video where we did rear shock re-locators on a '68. The nuts on the u-bolts were so rusted we ended up cutting them off.

[@craigdetroit]

It's like you guys are reading my mind!!! Thanks for the video!

[@renetorres1932]

Thank you for making this guidance videos. Thanks to yoy guys we are able to save alot of money on labor, therefore we get to buy more parts from you guys ha

[@BROTHERSTruckPartsTV]

We know it's a HUGE help to our customers, but it also helps us be able to provide Technical Advice as well as providing us a way to make sure our parts work as they should. Thank you so much for watching!

[@westonlee9778]

Do you know what’s the Max drop for a 63 without changing the rear (and front) inner fenders and other suspension parts? Is there any guidance about this? Thank you very much for your awesome videos and information

[@jeremycazares2960]

Are you replacing one spring at a time? To not cause the whole axle to shift around? I’m about to replace my rear springs, shocks, and track bar.

[@BROTHERSTruckPartsTV]

we are, but only because it's just the way we've been doing it.

[@aaronjohnson4557]

Does a 2” front and 4” rear drop require new shocks? I’ve been told that I don’t need different shocks for a 2/4” drop. 🤷‍♂️

[@bobshaffer3889]

Is there any way to lower the rear of a 1966 GMC 3/4 ton leaf spring truck 2 inches? Can't find any parts anywhere! Please help!

[@BROTHERSTruckPartsTV]

Your best bet is to use extended shackles or do an axle flip. Call the shop and we can talk about those options. 800-977-2767

[@donlewis1701]

Ok, I got my lowering put on. 5in in the back. I am waiting on my shocks . When they come in I will put them and the hard pan bar on. After setting it on the ground the passenger side is 1in lower why.

[@BROTHERSTruckPartsTV]

Probably just needs to settle, this is common. One short drive and it should level out.

[@dennisthemennis99]

When you did this, did you have to remove any brake lines or soft lines and then bleed the brakes?

[@BROTHERSTruckPartsTV]

You shouldn't have to remove the soft line to do this project, it should have plenty of length to provide space to remove the old springs. If it does not, we would suggest you start by un-clipping the hard line from the frame to provide extra travel in the rear end before you open the brake system. If all else fails, yes, you'll have to remove the soft line and bleed the system after reassembly.

[@raulloredo1628]

I have a 1970 c10 What’s the best way and what do i need to drop it 6 inches in the rear?

[@BROTHERSTruckPartsTV]

Easiest, least expensive way is to do a combination of 4" springs and a 2" block. We did this to our 1972 Suburban project a couple years ago and it worked great. However, once your get to 6" of drop, you're going to want to seriously consider a C-Notch. The axle will hit your frame on moderate bumps without one. It's tolerable for a while, but eventually you'll want one.

[@raulloredo1628]

@@BROTHERSTruckPartsTV thank you so much for the info!

[@jonrb28]

What wrench and sockets sizes were used?

[@BROTHERSTruckPartsTV]

Just standard stuff you've got in the toolbox at home, nothing special.

[@rubenfilippus2956]

I have a Chevy c10 truck and I don't know the year model and I want to fit it with air ride suspensions.where can I check to see the year model maybe? Thanks

[@BROTHERSTruckPartsTV]

You can figure out the year of your truck by looking at the VIN tag. It should be in your door jamb.

[@donlewis3191]

So it took forever to get my springs, still waiting on my shocks. My question is I started to install my new springs and the bottom caps are way to small.Top will work. Do I need a different set of caps and if so can I have part # and cost.

[@donlewis3191]

My springs don't look anything like the ones in the video.

[@BROTHERSTruckPartsTV]

Don, you're going to have to call the shop and see if we can figure out what's going on with your setup. Ask for Alex, he's the guru.

[@jimmiranda7181]

I don't see the Jack stand. Can I assume it is just out of view under the horizontal line of the frame. I am replacing both springs and the control arm bushings at the same time. You guys have everything, love the videos.

[@BROTHERSTruckPartsTV]

Yes, the stands are just out of frame of the camera shot. Thanks for watching!

[@jimmiranda7181]

Thanks for the info. I am installing my springs. Which direction do the pig tail ends of the springs point to? Or does it NOT make a difference so long as the cup are seated properly?

[@BROTHERSTruckPartsTV]

Just make sure the cups seat and you'll be fine.

[@Thatdudedoes]

I'm going to be purchasing your disc brake conversion with 2" drop spindles. Would you reccomend the 3/5 kit for a total of 5 and 5? Would that be too much? Would that potentially cause other issues?

[@BROTHERSTruckPartsTV]

This definitely depends on what year your truck is. Please give our customer service department a call before you order so we can get you set up with what you need and make it RIGHT!

[@nathanlovern5283]

Do I need a new pan bar if I put in lower springs? Shorter shocks? I have a 66 Chevy truck

[@BROTHERSTruckPartsTV]

It's always a good idea to use an adjustable Panhard Bar when lowering your truck. It'll help you get the rear end properly centered again. Other than that, you're good with the rest of the stock equipment if you just go 4".

[@peterhatch1583]

Yes. You can find our current line of products at www.brotherstrucks.com

@@BROTHERSTruckPartsTV do i need shocks if i installed air bags in the rear?if so what are good shocks for my truck.my truck has a 12"distance from the center to center bolts of mounting pads,and thats fully air out.

[@BROTHERSTruckPartsTV]

@@jimbo05551 Yeah, you're going to need shocks if you dropped the truck with bags. Ideally, you want shocks that are in the middle of their stroke when your truck is sitting at ride height. We normally suggest our line of shocks based on a specific drop, but since you have bags, it makes it a little harder to suggest a specific shock we carry. How much did the bags drop the truck to it's current ride height? If you know that, then you'll be in the ball park when choosing shocks from our website. Otherwise, you'll need to measure bolt-to-bolt at the top and bottom of the travel and split the difference.

[@alandust2188]

Does Brothers sell the non-adjustable tracking bar?

[@BROTHERSTruckPartsTV]

No, just the adjustable type.

[@iiRehab13]

What would you recommend if i'm wanting a 5in drop in the front and 6in in the back? 1987 Chevy Short bed.

[@BROTHERSTruckPartsTV]

We would go with a set of springs and drop spindles in front, and a flip kit with lowering blocks in the rear. We did all this on our '75 GMC as show in a couple of our other KZbin videos

[@iiRehab13]

Thank you for the reply! Could ya'll do a video on a Drum brake to Disc brake conversion?

[@BROTHERSTruckPartsTV]

Working on that right now... stay tuned!

[@iiRehab13]

BROTHERS Truck Parts Sure will!

[@BROTHERSTruckPartsTV]

Disc Conversion posted last week. We did a '70 C10, but your truck will be very similar. Thanks!

[@Roadglide911]

2” drop on the rear of a 67 c10 require any other modifications?

[@BROTHERSTruckPartsTV]

We would recommend using BROTHERS shortened axle bumper in order to maintain some of the rear end travel, otherwise no additional modifications are needed.

[@calilokifir744]

slam ur truck bro

[@TheCanadianBubba]

Gave a like, would have been nice to see exactly how to orient the plates... oh well, will keep looking

[@BROTHERSTruckPartsTV]

Yep, we see what you mean, but once you have the plates and springs together this orientation will become obvious. Thanks for the feedback!

[@TheCanadianBubba]

Yep... i see what you mean, totally obvious, i did orient the springs the same on both sides... seemed to do them opposite to each other might set up a bit of a twist in the setup... no ? both springs were wound the same... not opposites.

[@BROTHERSTruckPartsTV]

Won't be an issue, this is exactly how GM did it from the factory.

[@Luis-bk1my]

Will they fit a 1970 Chevy c20 truck ???

[@BROTHERSTruckPartsTV]

Absolutely!

[@adriantomlin2902]

How low can a person go concerning pinion angle?!

[@BROTHERSTruckPartsTV]

Pinion angle can be continuously adjusted, so basically as low, or high, as you want. At some point the u-joint get stressed, so you need to incorporate high quality u-joints into the equation either way.

[@adriantomlin2902]

@@BROTHERSTruckPartsTV ok gotcha!! Thanks a bunch.

[@CEPrepper]

Dude, literally skipped all the important parts for first timers. Where are you placing your Jack stands versus your Jack? How do you take the bolts off the top and bottom of the spring? Mine spin but don’t move up or down. I love these vids usually, but this one is a flop. 😢

[@theaveragebear7873]

Hi guys, I'm considering going with 4-inch drop springs in the back, which should get me leveled on my truck. Would a 4-inch drop in the back require a C-notch? Thanks.
