BACKSPACE QUESTION FOR 1969 C-10 dropped with pwr disk upfront - The 1947 - Present Chevrolet & GMC Truck Message Board Network

scott69c-10 · 12-07-2006, 11:12 AM

Can anyone help me with backspacing for rims for a 69 C-10 2WD fleetside longbed with 2 1/2" drop spindles, disc brakes upfront and 4" drop in the rear. Thanks!

I see a lot of guys use an 8" rim with 4" BS for the front and a 10" rim with a 5" BS on the rear.

not all dropped spindles are the same nor are all wheels made the same so its hard to give an absolute answer// i had 21/2 spindles with 15X8 ralley wheels(vintiques) with 4"backspace without a probvlem

i have 8 in drag lites on the front with 4.5 bs and mines droped alot. the rims clear the spindle by 1/4 inch but i dont know if the tire will clear a sway bar or not have not installed it yet. I have 12 wide drag lites with 6.5 bs on back

I have 2" drop spindles and airbags on mine with 20x8.5 wheels and they have 4.5" backspacing.

front 17x8, rear 17x9, all 4.5" bs

My rims are 15"x8" with 4" backspace and you can barely fit a piece of paper between the wheel weights and the new McGaughey 2.5" drop spindle. I had to grind a little more than 1/16" of an inch off the spindle for clearance.

I am running 5 inches BS on front with 20x8.5 inch wheels and 5.5 inches BS on rear with 20x10 inch wheels. I have ECE 2.5 inch drop spindles with 2 inch drop springs on front and 5 inch drop springs rear. I have no rubbing or interference issues whatsoever. I would have to be driving pretty fast and hit a dip or something just to even hear it bottom out a little bit.

Let me know if you need pics.

Nova,

Just about everything in you signature has been sold, does that me the truck is for sale also?! LOL.

boraxman · 12-08-2006, 11:09 AM

For further reference, I am running 15x8.5" with 3.75"BS with front disc...fit is perfect.

Ironically, it may be for sale soon. We are getting ready to purchase a new home and will need extra money for down payment, new furniture, and other expenses. Otherwise I had no intention whatsoever of selling this my baby. I have enjoyed my C-10 way more than all 3 previous cars put together!!! But as we all know, family priorities come first.

Cool part is that my wife promises to get me a new (well another 67-72) truck once we are all settled in
