Hey everyone, I've a 12 bolt rear with a 4:88 to 1 and am looking to 3:73. I've a M-22 in front of it and want to know if I should just spool it? Its fast as hell now at low 11's but can't drive it on a freeway!!!
any advice????

 

I wouldn't go spool unless it's strictly a straight line drag race car and since you are wanting taller gears I'd assume you want it more street/highway friendly.
With a 4:88 geared 12 bolt I'd guess it already has a posi of some type no?

 

Again spools are a pain to drive on the street ..I would just run a good posi in it Like an Eaton.

 

Agreed, no spool for the street.

 

Are you sure you don't want a gear vendor over drive or termac 5 or 6 speeds. They will cost a bit more but you will not give anything up. The Gear vendor over drive even claims highway driveablity and better 1/4 miles times.
