Looking for a spartan or Aussie locker for a 4cyl 2 pinion 30 spline 8".

Might also be interested in Detroit or grizzly

 

Prolly best to buy one new. Every once in awhile you can find "NIB never installed went another difection" they do pop up every once in awhile. I'd buy new. Good look.

 

No offense but better to buy new goes for probably 90% of the parts we want. Better to ask and get no response before I buy a new one than to see a barely used one come up for cheap after I buy a new one.

 

I know what your saying and understand. I've had both good and bad experiences. Been a couple places running sales.

You gonna install yourself?

Seems I kinda hijacked your post.

 

If it's a lunchbox locker I'll put it in but if I found a good deal on a Detroit or a grizzly, I'd get somebody I trust to set everything back up

 

i'd go with a carrier style over lunch box if money wasn't a concern. I've read grizzly is suppose to have a smoother operation but hard to tell from reviews. I'm running a lock rite in rear and seldomly notice it's there but I know where the quirks are and how to avoid them. It gives my wife and daughter hell though.

 

My rear is a welded Isuzu modified 12 bolt so it's not going anywhere. The only issue I have with the carrier style is this. The front R&P is going to be my weak link in my setup so my plan has been to find a spare 4.30 third. if I grenade one R&P, I can swap out the lunchbox locker when I change thirds (or have it already setup with a used lunchbox locker) and keep rolling. Good condition used 3rds have cost me ~$150. The price of a Detroit and having a Detroit setup properly in a third can get pricey, plus carrying a spare third with a Detroit already setup would be very costly.

 

I'm running my spare dif now. Grenaded a pinion bearing.

I don't know the 12 bolt mod. But switching to a hi-pinion in front as gears run on drive side, vrs coast side on low pinion is a stronger set up. Well one day I'll have a hi-pinion.

 

I'd like to have a HP as well but my trail truck is my cheap truck. If I had a $1000 to spend on a new 4.30 HP (I don't think they came from the factory with 4.30s did they?) I'd probably just start building a D60.

The 98+ Troopers have D60 sized, Drop out third, rear end with disc brakes, 1.5 axle shafts, a thick 9.66 ring gear and a tube the same size as a 14bff. They're 4.30 ratio so they can match yotas easily and was only $150 from the junkyard.
