rear ends - The 1947 - Present Chevrolet & GMC Truck Message Board Network

my 84 has a 454 and a 700R4. The usual engine mods, a loose converter and a 3.42 10 bolt. What are your experiences with these rear ends? I have visions of it exploding if this thing ever hooks. How strong are they? The truck will never see slicks or drag radials,(as of today)

Personal Experience. These will blow up. I blew mine apart, well actually sheared the right side axle shaft, which then twisted the driveshaft, & blew apart new u joints. Then as I was pulling it home (not realizing the internal damage to the rear end) the right side axle shaft and everything attatched to it 'walked' out of the housing.

I will try to post a pic of it shortly.

Here is the close up cell phone picture of the shaft.

10 bolt is a good rear end, for a lawn tractor. Get a 12 bolt if your going to use it for a working truck and the occasional stop light drags. If your going to hammer it, go for 14 bolt. jim

Hmmmm, I've heard many times that a 8.5" 10-bolt is pretty strong. I would be more worried about the 700r4.

I have used the 10 bolt for 5 years. Went through probably 6 bottles of nitrous with a 150 shot using a healthy 350. Never had a problem with the rear end but I did bust the tranny. I think they can be a good rear end as long as you aren't crazy with it. I agree the 700R4 would probably be the weakest link

iVE ALWAYS BEEN TOLD & THRU EXPERIENCE THAT THE 10 BOLTS ARE TOUGH REARS. MINE HAS HELD UP WELL THE PAST 7 YRS IVE HAD IT & ITS STOCK 1984. aND BELEIVE ME I HAVE FLAILED IT MORE THAN ONCE . TAKEN IT TO THE TRACK MANY TIMES . However I dont have gobs of power & torque. maybe 400 , no nitrous.
