Thats a good point from Pigdog, I've never used a mni spool so thats good to know.

What about a Full spool, anyone know if they are available?

Locked diffs are great for traction, but you can't turn them off. Having your car pig route around corners and such gets old pretty fast. Plus the axle life shortens lots.
If you want a locker, just weld one up. I'm very tempted to weld up one of my spares.

first off you cant actually get a mini spool for a h165 as the centre doesnt split you have no way of getting the mini spool inside

would have to be a full spool or a cig locker

i had a locked ute diff before the r31 diff and i reakon is was better than the mini spooled r31 diff. as long as you dont get any crap in the bearings or on the gears when its welded and you actually weld it up properly i dont think a mini spool would have any real advantage

i drive everyday on a welded stock coupe diff i dont mind it. the biggest down fall is they blow fairly easily. i have been lucky and been able to find more axles and centers at a reasonable price but at the rate im going there wont be many left. hehehe.

I have been driving around for about 3 weeks now on a welded diff, i have not yot tried it out on the track but even on the road i feel like i am in more control. when i put my foot down round a corner it powers through where as before, it felt like it coasted around corners. Even in the wet it feels good (driven carefully) before was a nightmare to get traction. I should have done it ages ago (i had nothing to loose as i have 2 h165).

can't wait to try it on the track so i can keep power on through the tight corners as my inside rear wheel always picks up of the ground.

maybee the best $0.00 i spent yet.

my opinon is as mini spool's are illigal why waste you money just weld it up with some plates in the center (nice and strong).

drive safe.

yeah im a daily driverso ill stick to saving up for a shortened LSD R31 diff.... maybe keep the H165 and spool it for other purposes...

hi guys i work for a company in sydney that makes custom diff stuff for any thing you want . a full spool is better than a mini spool because a mini spool is still driving through a single cross pin that is unsupported between the spool insert and the hemi case , wich leeds to pin failure in anything with decent grunt . a full spool even a one off custom is under $800. Might sound expensive but you will never have to touch it again . are you driving this on the road ? a spool or a welded locker is not recomended for road use . any intrest PM me for more details.

Good thing about the mini spool is
1. Reversable
2. I think makes better contact with axels - less likely to break axels...

There is a company called Lokka that make them in melb - I guess we could ask them...

When you weld it not much else can happen, unless the weld breaks!

i think i have a h165 in my ute... how badly does the weld locker damage the diff?
