yzrider Posted April 6, 2012 Report Share Posted April 6, 2012 The 88-89 diff and axles are obviously stronger I am swapping my 87 over to that and getting custom axles made. Has anyone had problems with the differential itself? im trying to make my car handle power without issue what else can I replace or focus on. I got poly rear mounts to help with wheelhop and will be getting d2s soon to dial it all in. Link to comment Share on other sites More sharing options...
The Rabbit1 Posted April 6, 2012 Report Share Posted April 6, 2012 custom axles aren't necessary. the rear end can handle a good 600hp while laughing at you. Link to comment Share on other sites More sharing options...
BOHO Posted April 6, 2012 Report Share Posted April 6, 2012 I've never heard of read diff troubles...but I've heard of axles breaking from as low as 240hp with a good hook...axles seem to always be the weak link... Link to comment Share on other sites More sharing options...

yzrider Posted April 6, 2012 Author Report Share Posted April 6, 2012 I've seen 6 bolt axles breaking on a weekly basis lately. Slicks and a prepped track are bad news. Link to comment Share on other sites More sharing options...
BOHO Posted April 6, 2012 Report Share Posted April 6, 2012 first I heard of it, Convette abuses them regularly, he snapped the driveshaft like a twig and the rear end is still doing good.. Convette probably has 370whp and isn't doing 4k clutch dumps with slicks if he wanted to...they would break....They will and do break.....4cylfury, Phinko, Serpent, Highlyboosted,....all over 400hp...have broken axles more than once....

craig87 Posted April 7, 2012 Report Share Posted April 7, 2012 Drag radials will break axles quicker then slicks. Highlyboosteds problems went away after he went to wrinkle walls good Cus it sucked putting axles in every Friday. Link to comment Share on other sites More sharing options...
yzrider Posted April 7, 2012 Author Report Share Posted April 7, 2012 Drag radials sidewalls are so stiff the slicks usually have some cushion to them. So really not much to worry about. Im getting custom axles and a driveshaft made for the car I guess there really isn't anything left to worry about. Link to comment Share on other sites More sharing options...
TainterRacing Posted April 7, 2012 Report Share Posted April 7, 2012 If you plan on putting alot of power down might want to work on getting a stronger then stock Rear U-joint I am going to assume your running a diff Transmission. Link to comment Share on other sites More sharing options...

BOHO Posted April 7, 2012 Report Share Posted April 7, 2012 yzrider... Where you gonna get your driveshaft done? Mine has 1310's front and back, aluminum shaft from Shaftmasters, I think you can get it from them in 1350's too. Driftmotion sells the r154 slip yoke in 1350 also.

Indiana Posted April 7, 2012 Report Share Posted April 7, 2012 custom axles aren't necessary. the rear end can handle a good 600hp while laughing at you.That's about when the rear stock 88/89 axles will fail assuming you aren't running slicks and the rires are hopping up and down. Easter is around the corner so I don't know what people have in mind. Link to comment Share on other sites More sharing options...
psu_Crash Posted April 7, 2012 Report Share Posted April 7, 2012 I didn't break axles... Yet Like others said I hope you have changed out the tranny before worrying about the rest. That is very likely to be the first thing broken. Link to comment Share on other sites More sharing options...
Convette Posted April 8, 2012 Report Share Posted April 8, 2012 Yeah its only a matter of time before my axles let go. They've been clicking for about 50k miles..lol. Clutch kicking 275s isnt the best thing for them. And Tech its hard to break something that doesnt move...lol My driveshaft only failed because I ran a hollow u joint. I then had an adapter built so that I could use 1350 spicers front and rear. I cant see spending near 1k for built stock axles when you could swap the whole rear for less than that. Soon enough I'll be doing something different. Link to comment Share on other sites More sharing options...
The Rabbit1 Posted April 8, 2012 Report Share Posted April 8, 2012 (edited) I cant see spending near 1k for built stock axles when you could swap in a much inferior rear for less than that. Soon enough I'll be doing something different.fixed. edit: I have to take that back, I just remembered you have the skills to make damn near anything fit, but if it came down to parts and labor you could not match the IRS AND power capabilities for under $1k Edited April 8, 2012 by The Rabbit1 Link to comment Share on other sites More sharing options...

I mean as far as going in a straight line and being cheap on cost then I guess it loses.. Link to comment Share on other sites More sharing options...
Convette Posted April 9, 2012 Report Share Posted April 9, 2012 I'm not talking about live axle my friend. IRS from a cobra can be found for around a $800 for the entire set up hubs and all. I did have to replace my torque tube once also. It didn't break, but the teeth were shot. Link to comment Share on other sites More sharing options...
