Re: 18"/20" Combo

What's the best way to achieve a 5/7 drop? My only concern is the roads around here are ROUGH! I know it's not going to ride like a Cadillac, but I don't want to go to the dentist after each trip for filling replacement. I am also on somewhat of a budget. I can't afford an airbag setup right now. What kind of clearance issues would I encounter going that low with 20's?

2"SPRING DROP + 3" SPINDLE DROP = 5

OUT BACK FLIPKIT W/ CNOTCH AND A SHACKLE = 7"

You will only have ride quality issues if you start half @ssing the drop.

Re: 18"/20" Combo

Thanks. Yeah that is why I am taking my time, and doing research to make sure what I want before I do it. That way it's not hacked up. That's not how I do things. My wife calls it Anal Retentive. I call it attention to detail!

The thing is I don't know if I want a slammed truck. I just like a little lower than stock, with a nice set of wheels and tires. Don't get me wrong I love slammed trucks, just don't know if I want this one to be that way.

Re: 18"/20" Combo

Hi John, i'm bumping this thread in hopes of more pic's and info. I'm on the fence also, but ready to pull the trigger on something. I wanted the 18/20 combo also and I do have a 5/7 drop, just would like to see more pic's of the setup. Also stuck between Boss and Coy.

Re: 18"/20" Combo

I say go with 20 inch Coys all around. 18s in the front look funny unless the truck is slammed.

Your truck does look good and I will probally go 20's in all 4 corners.

Coy is telling me I need 0 offset for the 20x10's, do you recall what you ordered?

Re: 18"/20" Combo

They were on the truck when I bought it. 20x10 with 5 1/2 backspace I believe.

Re: 18"/20" Combo

John C, Here is a pic of my 85 GMC truck. It has 18X9's up front and 20X9's in the rear with a 5" drop all around. I'm very happy with the stance but to each their own.

Re: 18"/20" Combo

I was planning on doing this just to get my front a lil lower because i dont have a "Z" or dropmember so it look funny(to me), when i slam the truck and the back sits lower than the front.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.

Re: 18"/20" Combo

I bought Toyo Proxes 2 and the ride with the 20's is nice . A little stiffer than the 18's I had on the tan truck but not bad at all . Better than I was expecting .

It's really depends on the shape of the fender openings. If you look at 67-72 trucks they seem to look just fine with a mild drop and staggered wheel size. That's because the wheel openings are rounded.

Now look at the large rectangular shape that the 73-87's have. The front and rear wheel opening is long at it exaggerates the difference between the two sizes of wheels.

Scoti's truck still looks good no matter what...
