stupid question buy hey i dont know
 

ok ive had a 71 4x4 for probably close to 10 years as an on/off project. ive never had it off road...hell ive never even put the front driveshat on.... what is a locker? and all the different diferentials you talk about im assuming some are more heavy duty or more rare. any place i can go to get some basic info on all this 4x4 talk?

You can visit the largest chevy 4x4 comunity on the web, which I'm a proud member of :flag:. www.coloradok5.com. Thats where the answers to all your questions are. Beware, there is a lot of hacked up sheetmetal over there. :metal: BTW lockers rule. :metal:

ill check out that site....not gonna tell me what a locker is?

A locker locks both axle shafts for traction. There are several different kinds. Most popular is the no spin detroit. A full locker differs from a limited slip simply because both wheels dig all of the time. These are most desired by the 4x4 community in the rear of their 14ff 10.5" ring gear axles. A locker in the front will get you alot further along an obstacle however it may reduce road friendliness. I've got a locker in the rear and a limited slip in the front of my trail K5. But only because I'm running a 8 lug 10bolt and don't really want to put too much strain on the axle shafts and ujoints. When and if I ever find a 1 ton front axle (D60) I'll go with a full locker in the front. Hope this helps you.
