: what to use to get rid of shock birfs poor boy pulling 11-05-2006, 06:09 PM i have a 76 axel with disks im assuming its a fj40 axel. its open at the moment, i was thinking of putting an arb in the front and i hear that the birfields are really weak and i have a sbc in it. any ideas? thanks chris Rat70FJ 11-05-2006, 06:35 PM Longfields. http://www.longfieldsuperaxles.com/ 65SWB45 11-06-2006, 08:50 PM Stock birfs aren't so bad IF you're the kind of guy that's mindful of your situation. First of all, NOT using the ARB all the time helps. Second, keeping sharp turns [while the ARB is on] to a minumum helps. If you tend not to be this mindful, longs are a good upgrade short of replacing the whole axle. You might get more responses if you post up other specs on the project e.g. tranny combo, tire side, steering setup. Chances are, once you post tire and steering specs, you're gonna get an earful [or should I say eyeful] about at least upgrading the knuckles as well. Hth Mark BTW, the 45 seats passed the first road test to Mesquite with flying colors! ranger 11-06-2006, 09:03 PM Bad combination, locker, wheel cranked all the way, reverse, heavy foot. :nuke: Nothing sucks more than wrenching on your rig when you could be wheelin. J-Ohlin 11-07-2006, 07:09 AM x2 on the longs. Just put em in and go. cruzila 11-07-2006, 07:32 AM If you go bigger than 35's you need Longs. You can wheel for a long time on stockers if you do like Mark says. I have proven that over the years. The reverse thing is a real deal. :nuke: That said I just recently went to Longs in my cruiser. I have already been in a situation where I would have backed off with stockers but did not this time. The Longs held fine.

I run 35's on mine with a 400 sbc, 465 and stock axles with a lock right in the front and welded rear. In the 5 years I've been wheelin it I've only brock 3 birfs. If you know what it takes to break them you can make them last. Rat70FJ 11-07-2006, 06:38 PM In the 5 years I've been wheelin it I've only brock 3 birfs.

The point behind the Longs is not having to deal with this part DHONDAGOD 11-07-2006, 09:31 PM I put 30-spline Longs in mine with a Detroit in my cruiser... 2F, sm465, dana300 with Lo-Max 4:1's, 4:11's in the axles and 36" radial swampers... I enjoy not worrying about the birfs..... Piece of mind is a wonderfull thing.... Chris:cool2: | |
