No you don't need them. You don't need life insurance either. You'll probably not die.  :screwy:

Okay, so I'm looking for a proven cheaper alternative

There are a few things not to go cheap on with these trucks. Axle shafts is number one. Bite the bullet and get a RCV. They can be had for $612 here: http://www.jesterfab.com/collections/toyota/products/rcv-300m-chromoly-birfield-axle-set

Ill willl book mark it and probably end up going with the best. I like the piece of mind, but I also dont beat on my truck and dont bind my stuff up like ive seen. Real quick do door add much cab safty in a roll over situation? I want to get them off in the spring.

Honestly they are pop cans with or without the doors.

Don't skimp on axles. I have og bobbys in all of my rigs. Never broke one. I've killed numerous stock birfs. I would say yes the doors do help a little. But not enough to justify sweating your butt of when it's hot. I prefer tube doors. Also a good option is a small cage or at least a hoop behind the cab.

Thanks for the reply guys, I kinda wanted to get a in cab cage but not sure yet on that, got some sliders on order right now. Just relized my truck has the pimp lean to passenger side, pad is welded on the drivers side and ended up leaning passenger after settling ha! What bs. Rcv and go ahead and save and get the hub set to? All these little things that keep happening. Something is always acting up. But its all worth it when you get to the trail!

I run trailgear longfields. I got them on closeout pricing before the gun drilled came out i build on a budget so i chose what i could. My first gen has 27 spline longs in it.

IMHO my answer is yes you need them. Considering the first Birfield I blew was a low speed backing up in camp on flat ground. It screwed up the ball and took the splines off the stock shaft. Worth the money, yep!! :gap:

Thanks for the input guys, I debated selling my truck but then realized I would regret that for the rest of my life. I got rock sliders in the garage needing paint and welded on, any cage ideas? I thought about an exo off the sliders and down to the stinger In hope that it would save the pillars in a roll over. Next on the list is front shafts and cage and its closer to being done. I was thinking of going with a tube camper with a canvas top. Any recommendations on the interior? Carpet or bed line?

Gotrocks had chromoly upgraded front axles on his first gen 4Runner on 37s and he broke them both plus one of the stock replacements in two days in Moab. He wasn't easy on it, but wasn't abusing it either. He had the original Longfields overnighted (currently RCV is the equivalent) and saved the trip. He tried to save some cash with the chromoly shafts and it didn't work out for him at all. I have successfully run 33s with a Trutrac limited slip in the front of my 85 truck with success but did original Longfields when I did the Aussie Locker and 35s.

Arp knuckle studs and hub studs, hopefully these axles are shimmed correctly and it will be a breeze. Im gonna do the camo method seemed to be the best way.

If you haven't gotten into the front axle before I'd recommend tearing it all down to get a good look at every part

I have gun drilled 30 spline in my rig on 37 stickies behind an LS and Atlas and so far hold up great other than stripping splines once
