locker advice. - broncosbybart - 01-05-2011
I posted up on classic as well. What are your thoughts on this all?
I am thinking of the race rig. The ECORS courses are set up here in the southeast, and range from doing laps from 3 miles to 15 miles, with a time limit of 2 hours (total distance is usually around 30 miles). The courses are set up with some flat field type sections, some wooded, and a few rocky and technical sections.
The rules only allow for 1 locker but the other axle can have a posi. I have a few lockers at my disposal, so here are my thoughts. I could run a rear limited slip and an ARB in the front, or run a detroit or spool in the rear and have a limited slip front. Which do you guys think would be best and why? I watched a few guys last year and it looked like some had the locker in the front and not the rear, but others complained about severe understeer like that. I will be running a 44 front with drive flanges (axle shafts always engaged) and a D20 twin sticked.

I think I would prefer the limited in the rear and arb in the front. this will fix the steering issue for most of the area and i think the limited is better served in the rear for a race course since most of it is not big bad obstacles. i am not racing experienced but just looking outside the box.

When I did timed obstacle courses in my one of my CJ's, it had an ARB in the front and spool in the rear. Low speed and tight turns were hard because the rear axle would push the front end to the outside edge of a turn. This was also with boggers/double beadlocks running 5psi in the rear.
Some of it may depend on your driving style, but I would prefer a limited slip in the rear and ARB in the front axle.

will a ABR react fast enough for sudden steer situations?

I would think a locker in the front would make steering a PITA and the Dana 44 may not take much abuse without spending even more $$ on stronger shafts. I have a locker in the back of Jessica's rig and love it. It all depends on your driving style and the course though - some courses may be better suited for one setup than others.

Yes they will, once the button is press its one.
My thought has been Detroit or spool in the back and the arb or posi in front. The courses for A class seemed to be more open roads and less rocky sections. I high speed with the locker in the front and no hydro steering. It would be a pain to turn. The thought also would be with an arb in the front you could run both A and B classes.

I used a manual switch for the ARB. It took about 1 second to engage, and a fraction of a second to disengage. Power steering and 38.5 boggers were a little tougher to steer with it locked in. No problem with it open.

As far as breaking the D44. It depends on how you drive. I used hub fuses on warn premium hubs. Never had anything broken, but I tried to avoid shock loads. I've also run 35" tall (37' boggers) on a welded Dana 30. I only broke an axle u-joint when coming off a culvert, one wheel landing and having power to it.
The landing looked something like this:
