Was going to question the 9000 pound winch rule but i'm cool with that now, going to rear mount it and run cable/rope through eyes to the front housing.

The rule that states front and rear diffs must have 100% locking devices, i guess this is pretty self explanitory huh, so no traction control ?
Winches need to be 6000lb minimum.

Traction control will be fine - it is 100% locking in terms that it can make both wheels turn at the same speed.

can i ask why both diffs need to be 100% locking? listening to dustin (or was it little rich) at the finals whoever it was said that some of the yankie rigs only run an lsd in the front... surely if i want to not run a locker in the front, the only person disadvantaged would be me.

An LSD that is Shimmed and running the right type of fluid will lock both tyres easy as. Once again 100% locked (even if its only for a short period). You will also find that he is probably refering to a Truetrac, they are an LSD but works nearly like a lockright.

I couldn't see a drama if someone wanted to run LSD's, however i do think they would be at a big disadvantage. Why not just weld the centres!

he was saying that alot of compeditors prefered the steering accuracy afforded by not having the front wheels locked. i was just asking the question of why it was part of the rules. i mean i understand the safety and logic behind a winch capable of self recovery, and all the safety aspects in the rules, but the "must be 100% locked diffs front and rear" i couldn't see a safety aspect addressed by these rules

I really can't see why you're questioning this rule, its there and it will not change.

I already said that i can't see an issue with running a LSD and i am sure that if you contacted Sam he could discuss this with you.

I am thinking that the rule was implimented to stop people entering with open diffs and weak LSD's. The main reason an event organisor would not want these rigs is simply due to the fact that they would be getting stuck on every course and needing recovery, hence slowing down the flow.

If you are keen on building something and want to run LSD's then give Sam a call. Simply as that.

You could possibly learn Jody`s front turn burn and rear turn burn and run full spools front and rear

The only disadvantage to running a locker in the front is that you cant get full lock easily and ofcourse weakness to the CVs when cornering......

most of the guys run the hydro steer and it seems to push the wheels to full lock anyway..... though the stress on the CVs would be farely hecktic..... at least on stock Cvs...

i can see why the rule is there, i can also see y its not really a safety issue... but at the end of the day a rule is a rule, and if ya just follow them, everyone is then in the same position and makes for a more consistant and even event....

As Promoters we found that with the difficult terrain that the vehicles are running, rigs must be equiped with some sort of locking differential. The last thing anyone wants is a vehicle that is not going to finish the course, taking all the time and getting stuck. It slows down the show, creates new obsticles by digging holes (That could be avoided by a locking diff), ties up the recovery rig during the event.

To clear the air...we run (on our CTM'd Dana 60's) Detroits in the front of ALL of our competition rigs and ARB's in the rear...yes, there's strategy in that and you'll have to figure out why.

Those that "overheard" my story might have missed some of it so here it is.
In my first year of competition (4 years ago), I drove a "STOCK" CJ-7 in the Pro Modified class of CalRocs (the old WE Rock). It had an AMC 20 in the rear and a Dana 30 in the front. In the rear, I had an ARB, in the front I had a real Limited Slip style differential (the kind with clutches). I kept my mouth shut and was never called on this and actually fared VERY well in the series, even though we were outgunned by the real competition buggies we were up against (Pro Mod used to be the toughest buggy class to compete in and is now scaled back with frame and steering rules).
The reason I ran an LSD was because I knew the Dana 30 wouldn't hold up and if I needed it to lock, I could just step on the brakes and it would work just fine...it did and we did well...however, I see trail rigs all the time with good drivers that can't drive an LSD and truely would need a locker to get into their driveway...Like rear steer, driving with LSD is something not all people pick up quickly. Put lockers in and the events flow faster and more people have successes.

I was driving on the weakest axle in competition with NO upgrades...
With the technology available nowadays for cheaper than ever before, I wouldn't make the same decision. Shoot, a Toy axle with stock birfs is stronger than a D-30...

thanks for clearing that up for me.
