12 Bolt ?

[2bhntn]

Howdy. I have a 90 FS Jimmy. A couple years ago I swapped in a 12bolt. I am now getting close to needing a rebuild or replacement. I was wondering if anyone has any opinion on the 12 bolt ? I noticed that most every on this forum is running the 14 bolt FS. I like the MT Rims I currently have on the truck and don't really want to swap in an 8 lug. This truck is a daily driver. I do get in the mud with it some but nothing like most you fella's. Thanks in advance

Also is there a recommended rebuilder ? I saw one online not that long ago where you could basically pick what options you wanted and then spit out a price. My Hardrive crashed a few weeks ago and I lost that bookmark.

If you really want a 14FF but don't want to convert to 8 lug, Check with this guy: Grady's Extreme OffRoad
He has 8 to 6 lug hub conversions! His name is Grady. I have a built 12 bolt in my rig now but I am considering the 14 FF w/ conversion!

personally i wouldnt keep the 12 bolt, they have weaker thinner pinion and tend to have more of yoke nut coming loose problem than 10 bolts and other axles,

and thres been past discussions all about 8 to 6 lug conversion kits, theres a few now. http://coloradok5.com/forums/showflat.php?Cat=&Board=blazer4x4&Number=515195&page=0&view=collapsed&sb=5&o=&fpart=1

another option,mabey,would be to get a 14 bolt,then buy the 8 to 6 lug adapters,temporarily.that way you could keep your rims for the time being,and still have a 14 bolt.just an idea YOURS TRULY HI PINION /forums/images/graemlins/cool.gif

Thanks for the opinions on this. The wheel adaptors, anyone have any experience with these ? Are they safe ? Temp only ?

Do I need a 14bolt or will a 10 bolt do me just fine for my use ? The truck as 35inch x 12.50's and a 350. I get into some mudd occassionally but mostly just my daily driver.

So the 12bolts suck huh ? Damn

35's is about the max size you can put on a 10 bolt. anything bigger and you might end up braking axels. If at anytime you forsee going bigger, Then i would go 14ff and get it over with. There are plenty of people running 10 bolts with 35's. I did with another truck. The only problem I had, was it kept spitting out spyder gears. Sold the truck, otherwise I would have put an eaton posi in it. 10 bolts are "supposed" to be stronger than a 12 bolt. The pinion bearing on a 10 bolt is a little bigger. but they still go bad.
