    Planning ahead for 3/4T 4WD Suburban suspension

    I've heard the difference between the Tuff Country EZ ride springs and the HD springs is they put an extra leaf on the bottom of the HD pack. If it rides too stiff you can remove that bottom leaf. I don't know what the difference in cost between the springs is. I was running 285/75R16s with...

    Planning ahead for 3/4T 4WD Suburban suspension

    One of the build versions of my truck was some 2" Tuff Country HD front springs, removed the sway bar, Bilstein 5100 shocks, 3" block for the rear springs. I was still towing and hauling firewood so wanted load capacity. It still rode better than it did stock. The HD front springs actually...

    Why is it so hard to find a rear shock mounting bolt 1980 Chevy K20 - Help Please

    Sometimes. Depending on the brand often that shock part number also works on other vehicles. Lets say maybe a Dodge truck. They don't use the same mounting hardware so the shock can ship without any hardware at all. With all the rust and de-icer around here I have been buying stainless bolts...

    8.1 vortec into 1979 k30

    I was going to say this. I read something like 33 pages of stuff on his blue truck and I thought he was doing it again on a Suburban. I read it on expedition portal though.

    Smooth ride

    For the best ride possible there is custom coil overs from offroad design. Or custom leaf springs from offroad design, or even custom leaf springs from Deaver Spring. Then get some good shocks. offroad design website

    New here thanks for having me 86bluek10 with k20 axle 6 inch BDS lift 37in tires on 20 rims but changing to a 16 in rim soon

    Do you feel the shake more in the seat (rear axle) or thru the steering wheel (front axle). Ball joints good? Steering box tight on the frame and frame not cracked? You might look at a 17" wheel instead of a 16" to change the subject to you looking at new wheels. Lots more selection in a 17 vs...

    Need help with a lift kit….

    I thought all the lift kits were the same for all the years (except for the 1 ton trucks). The only difference I know of would be some of the kits had a brake re-location/drop down bracket. But thought that was for trucks '81 and up or something. Or if it came with brakelines then they...

    New "Old" Daily - 8.1L

    I had a 2003 Silverado 2500HD with the 8.1 for around 10 years. I also had the oil consumption issue but on the Silverado forum they suggested just using a heavier oil. Being that was my summer tow rig I had no problem switching to a heavier oil. Started using Mobil 1 synthetic 10W40 and by the...

    First Square body

    Flathead valley area- used to like this area but it is too expensive and getting to be too many people. Want to move but need to wait for the kids to graduate high school. :(

    First Square body

    Welcome from Montana. When trying to close the hood results in you doing a chin up it is time to lube up those hood hinges. :)

    cheap paint job options

    I used Monstaliner back in 2014 and it is still holding up well. Roughed up/sanded the existing paint then mixed the bedliner and the color tint then just rolled it on. 39 colors available now. click me I *think* I just ordered a 1 gallon kit ($154.40) and the color tint ($31.75).

    Leaf springs

    I'd check out Rock Auto. They are a sponsor here so you can get 5% off. They list leaf springs by weight capacity and how many leafs are in the spring pack. There were several different options of springs available on all trucks. I bought my longer rear springs from them.

    Gov loc differential???

    I had a 1998 ZR2 that had the G80 from the factory in the rear axle. At times it would engage rather rough but never had issues with it offroading. It was only on 31" tires. I was on a ZR2 forum back then and failures were not that common unless someone was doing something very stupid. I had a...

    Equal - Tire Balancing Beads, No weights to Lose

    I just realized I never updated this thread. I bought some KMC beadlock wheels and some 37x13.50 tires in September of 2020. Mounted them in my garage and used airsoft pellets. I had bought some MetalTac Airsoft BBs from Amazon. Came in 2 packages. 0.25g and 8,000 rounds. I split those into...

    What are some options for mud flaps?

    Both the squarebody trucks I bought in Montana had mud flaps from the previous owner. Even on my dad's truck he has Peterbilt rear flaps and Yosemite sam back off front flaps. They have since been ripped off after dragging the bumper thru the tank trap section at the local off road park...

    17 inch wheels

    The closest wheel I can think of for you to compare is the old Hummer H2 wheels. They were 17x8.5 and had a 5.5" backspace. I've seen several run those on squarebodies. :shrug:

    17 inch wheels

    Doubt you will hear back- that was a post from 9 years ago and the poster hasn't been back in 8 years. Although the wheels would probably fit I'd think it is better to stick to roughly around 4" of backspacing.

    The Future of Battery Electric Vehicles (and I don't like them)

    You are assuming there will be a choice in the matter. I'm thinking that they will just make sure the price of fuel stays high- and then goes higher. That way there is incentive to go buy an expensive EV. Then when that fails start doing penalties for driving a gas vehicle. Extra road taxes...

    BFGoodrich or Cooper?

    BFG claimed the sidewall tread was designed that way on purpose to help tip/guide potential hazards away from just getting jammed straight up into the sidewall: The tire manufacturer claims that the KO2 sidewall is 20 per cent stronger than the original KO tire, and incorporates an advanced...

    79 k10 Newbie issues. Stressed out Mom, please help!

    Did this truck supposedly run and drive before the rear driveshaft was removed? So far I'd think the transmission is slipping/transmission is bad. Especially how sometimes it would move a bit with lots of gas. Was the trans fluid dark/burned when it was changed? The 203 transfer case is a...

    The Future of Battery Electric Vehicles (and I don't like them)

    150 birds was just bald eagles. And since they think there are only 300,000 bald eagles in the US that is why the number is small. According to the Sierra Club around 1 million birds are killed per year by wind turbines. Think that number is bad? Power lines themselves are 25 million. Cats? 1-4...

    Selecting offset wheels for my Lifted 85 K20

    I ran some cheap Vision Soft 8 steel wheels with a -6 offset (4.25" backspace) wheels with 315/75R16 tires. Worked fine for me.

    The Future of Battery Electric Vehicles (and I don't like them)

    Montana has 64 charging stations so far in a recent EV article I've read. This is a big state and it can get very cold in winter. Not practical for most people here.
