Re: which spool do i need

If it's the factory truck 12-bolt, it'll have 30-spline axles. If you're going to a spool, you should consider a good set of axles anyway. Something else you're going to need is a set of c-clip eliminators; that is, if you end up putting a spool in it.

Re: which spool do i need

You must have c-clip elimators to put a full spool in it and to put c-clip elimators in u must get aftermarket axles. 33 spline should do ya good assuming your making under 700ish hp. You can run a mini spool with stock axles but I wouldn't reccomd it all unless you think going down the track on 3 wheels is fun, been there done that. Chris.

I would go with the Mosier spool and axle package its very affordable.
They give you options of lug pattern, stud sizes and axle spline sizes
