if that is where you are getting wheels, I would plan on buying spacers at least for the rear.

That is the only sizes they make. I checked the manufactures website. What rear axle would I need to eliminate the spacers? Just the blazer one?

yeah a 4x4 blazer or truck axle will eliminate spacers. if you plan to tuck the front dont get a zr2, it will look really wide compared to the front if you go with a standard backspace front wheel.

Found a cool gas cap and never posted pic of light brackets.

Put a neutral safety switch on a 700r4. Built this bracket. I used a 4l60e neutral safety switch and shifter shaft.

[joedoh]

good thinking!

Very cool. I'd like to know how it hooks up if you don't mind PM'ing me. Don't want to hijack the thread.

I am trying to duplicate what you have done with the neutral safety switch. Where did you get the longer 4L60E shifter shaft?

Thanks.

I went down to my local transmission shop. Just make sure the one you buy is for the 4L60E as it is longer.

So I am finishing up a few things. The truck is in the shop getting the exhaust finished up so I am revisiting the wheels. With these wheels Classic Torq Thrust II 20x8 5x4.75 4.5" Backspace how far in will the wheels be? I have not been able to find something with a 3.5 backspacing. What if I stick with this size wheel for the front and back? Do you suggest wider in the back? Also what size tires did you end up using?

if you havent swapped out the rear axle, you can use that size front and rear and a 2-2.5" spacer on the front and a 3" spacer on the rear.

I have never used a 4x4 axle. when I did the 20s without spacers I used 20x9 with 3.5" backspace, on this truck I have 20x8 with 4.5 backspace and a 3" spacer on the rear, on another truck I did a 15x10 (rears) with 4" backspace and no spacer, on yet another I did 15x8 with 4.5" backspace and a 2" spacer. There are a lot of ways to get there. If you did a 20x10 with the least backspace they sell, I think is 4", and the 20x8 on the front, it would look astounding but you stil lmay need a small spacer on a stock s10 axle.

What about a 17x7 Wheel with 4 backspacing 0 offset? I basically want this style of wheel https://www.americanracing.com/wheels/torq-thrust/ with no spacers if I can. The bigger the better but anything 17's and over should be good. I do not have a problem swapping out the rear end. I am more worried about the front. All the wheels I found that were 20x8 with 3.5 backspacing were $600 per wheel.

backspace is the wrong way to talk about what you want your wheels to look like, so lets talk about FRONTspace instead.

first a little info:

backspace and wheel width mean a lot, offset and wheel width means even more. a 4" backspace 7 inch wheel will fit (very) differently than a 4" backspace 9 inch wheel. this is because of frontspace. same thing with different widths but having the same offset.

wheel width is measured bead to bead. a wheel is ~1" wider lip to lip than its stated width because of the lips. so a 7 inch wide wheel is 8 inches wide with a tape measure lip to lip. a 6 inch wheel is 7 inches wide. etc.

backspace is the measurement from the rear LIP to the axle mounting surface.

offset is the measurement from the wheel centerline to the axle mounting surface.

this is why I talked about the width lip to lip measurement, because backspace takes 1/2" of the lip into account. so the wheel you just described, 7 inches wide, 4 inch backspace, 0 offset. 0 offset indicates the axle mounting is exactly in the center of the wheel. a 7 inch wide wheel is 8 inches wide lip to lip, and 4 inches of backspace means the axle mounting surface is indeed in the exact center.


to run without spacers, I know that a 10 inch wide wheel with 4" backspace will fill up the rear fender, no spacers. this is what it looked like.




a 10 inch wide wheel is 11 inches lip to lip, and 4 inches of backspace means that the wheel has 11-4 =7 inches of frontspace.

compare that to your 7 inch wide 4 inch backspace wheel, it will have 8-4 = 4 inches of frontspace. thats why wheels like this need a 2.5-3 inch spacer.


in the front I think that same truck had 15x8 with 4" backspace, which is 9-4 = 5 inches front space, and it looked great. it may need a 1" spacer in the rear because the fender spacing seems to be different front to rear on ADs, there is more width to the fender in the rear.
