how can i tell if i have lowered spindles? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

lotus · 08-27-2010, 05:07 PM

I bought a 63 chevy truck that has disc in the front. supossidly it has lowered springs on it but the previous owner does not know about the spindles. I am heading down to get some different front wheels put on in a little bit and when they have the tires off what can i look for to determine if I have lowered spindles.

I don't think it does. the front is not very low. front tires are 235x75x15.

I eventually want to move the 235x75x15 to the back and put 215x75x15 in the front and bring it down a little bit.

Regular spindles will have a "straight" arm that connects to the tie rod end.
Drop spindles have a "curved" arm that connects to the tie rod end.

thanks Keith, mine are straight so it looks like i have stock front spindles.

just found out my fronts are 5x5 bolt pattern with disc brake. I wonder if it is as simple as putting on a 5x4 3/4 rotor to convert?

www.performanceonline.com sells a "conversion" 5x4-3/4 rotor for the truck spindles, that originally had 1.25 wide rotors. Look them up online under the 63-87 truck section.
(I would find you a link, but my "dial-up" service is terrible today)

If your truck is equipped with 1" wide rotors,... that will be more complicated.
You would have to swap spindles, and calipers also.

Are you trying to convet to camaro style bolt circle? Is the rear 5 on 4 3/4?

i should be ok then. I am going to be buying lowered spindles anyways. I was just curious how much new disc brake stuff i will have to buy with them.

The rear is still six lug.

I have no problem staying wide five bolt pattern. It just seems to limit the wheel choices i have.

It will be a couple weeks before i can afford anything so i have some time to research it.

I would stay 5x5.
Remember 5x4-3/4 is a car pattern.
Most of the wheels have a smaller center bore to match the car rotor.
There are actually alot of choices in the 5x5 pattern.

Another option would be to use an aftermarket 6-lug rotor.
They are a bolt-on rotor to what you have also.
That way you wouldn't have to do anything with the 6-lug rear axles.
