psu_Crash Posted March 28, 2010 Report Share Posted March 28, 2010 Still running the 4 bolt in my '86. I know the 6 bolt axles are stronger but it is something I should be worried about? Currently have the rear end out of the car and I regreased and inspected everything. It's all in spec and looks great. In the very near future though I will be putting some substantial power to the wheels and I'm looking for some thoughts on it. I have no intention of dragging the car. Some auto-x here and there, but for the most part just a street/highway animal. Link to comment Share on other sites More sharing options...
Funky Phil Posted March 28, 2010 Report Share Posted March 28, 2010 Just stay away from wheel hop and the 4 bolts will be fine. hell, wheel hop will kill the 6 bolts. I think you should be more worried about your trans to be honest. Link to comment Share on other sites More sharing options...

I think you should be more worried about your trans to be honest. That thought has crossed my mind. As soon as I realize my clutch isn't up to par for the power I was thinking that would be a good time to swap the tranny. So far wheel hop has been a non-issue but I'll be sure to keep mindful of it. Thanks for the input Edited March 28, 2010 by psu_Crash Link to comment Share on other sites More sharing options...
strang3majik Posted March 29, 2010 Report Share Posted March 29, 2010 the only thing keeping me from ever swapping was the fact that, the 4 bolts you can still get parts for, whereas the 6 bolts are a little more difficult if you can even find any parts. But...my thought, unless your dragging the car, or making pretty good power...thats the least of your worries. Believe me, the trans will give out first. Two of them to be exact Link to comment Share on other sites More sharing options...
dmyers151 Posted March 29, 2010 Report Share Posted March 29, 2010 Yeah dude, your 4 bolts should be fine for what your plans are. It's abrupt, violent surges of power that will break them, aka drag racing. Link to comment Share on other sites More sharing options...
Komeuppance Posted March 29, 2010 Report Share Posted March 29, 2010 The 6 bolts are heavier. The diff is 10lbs heavier by itself. This is another downside. -Robert Link to comment Share on other sites More sharing options...
joey_crandall Posted March 30, 2010 Report Share Posted March 30, 2010 there was a video of a ls1 quest thats was boosted and it was still using the 4 bolt. Link to comment Share on other sites More sharing options...
mistapickles Posted March 31, 2010 Report Share Posted March 31, 2010 I did the swap from 4 to 6 and had an axle go....lets just say I'm working on finding something that I can fabricate to work on our cars...something strong and more common, like a honda, or strong, like a Porsche Link to comment Share on other sites More sharing options...
