Detroit Lockers or Aussie Lockers
B52BUFF:
I have narrowed it down to these two types. What are the opinions on these? I am installing Dana 35 chromoly (30 spline) rear axles and plan on installing a locker also. I had contemplated putting in a lunchbox locker but was under the impression that Detroits were better. I was also told to look into Aussie Lockers and did so. The Aussies are cheaper but what would be better in the long run?

aussie if you break a shaft a dertoit may eat its self if you are on the throttle when it happens and the nice thing about an aussie you can install it in less than an hour
yes the way a detroit works is better only allowing one wheel to accelerate faster
an aussie will allow one wheel to move faster or slower which ever is easier
since both are not selectable lockers i say go cheap go aussie

Since you are not planning on regearing right now I would go Aussie. If you were going to regear and already have a lot of labor expense going into it the Detroit would be good at that time. I went Detroit in the rear of my TJ because I was getting the axle regeared and the Detroit replaces the entire carrier so it is stronger than the stock carrier and then a lunchbox. I think the guy in the white YJ killed his Aussie today. After that last circle his rear axle was just clicking as the wheels turned. He said he was going to take it apart when he got home, but he's running a D35 with 35s and his tire wasn't coming out the side so he thinks he killed the Aussie.

Wha do you mean by "Re-Gear"? What are you regearing?

Regearing is when you change the gear ratio in the axle differentials. TJs come stock with either 3.07 or 3.73 gears if I remember right while Rubicon editions come stock with 4.10 gears. The factory installs gears that they feel are the best compromise between gas mileage and performance. The problem with installing oversized tires is that the Jeep will become very sluggish at acceleration and may cause you to downshift a lot on hills on the highway. To get the original performance back from what the factory had installed you need to regear the axles to meet the needs of the oversized tires. Here's a chart that shows some gear ratios to performance. I'm currently running 33" tires with 4.56 gears, but will be upgrading to 35" tires in the future. According to the chart I'm running the in the best overall performance category with my set up.
