Ive got a 79 blazer with an 8.5 10 bolt up front. Ive got superwinch hubs and a modified NP203. I dont do
alot of rock crawling. My rig is mostly snow and mud driven. Im trying to make up my mind on wether or
not to use a spool in the front. Spool vs. Limited slip vs. open. I need to input what do you guys think?

thanks

You'll break something with a spool-I'd leave open or go with limited especially in snow/ice

With a spool, you will have a very hard time turning, with the front axle engaged. A locker will still give you differantial action, but still be harder to turn than open. I run front and rear lockers in a high horse short wheelbase Jeep, and have come to the conclusion that, the only people that complain about lockers, are those who don't have lockers. IMHO, get lockers, adjust your driving style for road conditions, and leave the lockerless vehicles behind. Stay away from spools, they really have no place on a street or trail machine. I ran a spool on a street/strip car, and wore out rear tires in 1000 miles. I know that has nothing to do with the front axle on a 4x4, but a locker is a better solultion, and lockrights or EZ lockers really aren't very expensive, especially for the 10 bolt GM.

Thanks, Ray
