hay guys,
I am starting to build my first mud truck and have already learned alot from reading the posts in this forum. my question to you is why would i need to have two transfer cases? Other than it being fun to watch rooster tails shoot to the tops of the pine trees out of the front wheels is it important to be able to only lock in the front axle? And is having the ability to only lock in the front the only reason for two tcases.
I am going this weekend to pick up my new and first mud slingin project.
it is a bronco. i picked this rig becouse it is only $500 . I have a 460 sittin here that needs a good home so hmmmm remove the broncos 302 and slide in the 460 who knows i guess that is for another post.
Back to the topic, why would a mudslingin rig need two tcases and do you recomend one for my weekend mudslingin swamp buggy with posibly a 460.
you only want two t-cases for really low crawl ratios....in mud you want higher wheelspeeds, so you only really need one t-case..usually a 205's apprx 2:1 ratio is plenty, and you can do a twinstick mod on the np205 so you can control front and rear axles sepratly....you can put the rear in 2hi or 2 lo, anf same for front...very easy cheap and effective mod
as for lockers, you would want to lock the rear before the front...but preferably lock both axles
actually doublers are more geared for rock crawling than mudding....the advantage to doubling is having a 4:1 ratio instead of 2:1 at the Tcase....the front wheel drive part comes from the NP205 not the doubled 203...when you twin stick a NP205 it gives you a shifter for the front axle and one for the rear axle, so it a tight situation you can lock the rear brakes and drive with the front axle to pull the front of the truck around a sharp turn...or vise versa...
EDIT: Kabota beat me to it!!

Only time you really need lower gears then a NP205/208 is if you're doing some nasty trails or in the rocks. This can be for the ability to "bump" up obstacles, or to keep the transmission cooled, or a handful of other situations. You do want to be in low gear though in the mud. Even if you are using 2nd and third instead of 1st and 2nd in high. Gives you more gear reduction on the engine's power.
Just ask Monsterbaby about how he embarassed a competitor (one of the only two that can beat him in open class...and barely at that) of his that runs the laughing gas when he tried to race monster in high gear. Blew him away...that was a good day for running.
I believe this is the race you are refering to where the other truck decided to try running high range, for reference he is running paddle tires, 514cid ford and 250hp shot of nitrous in this vid, and normally it's real close between the two of us until I put the 39s on.
just more options! you can't have to many options when you can potentially get in some serious sticky situations! not only will it allow you to crawl at extreme low speeds but will also help tremendously when navigating down hills!
Thanks for the reply.
My questions have been answered. I will stick with only one t-case. I will also look into the np205 and posibly a twin stick mod.
Is the np205 t-case the way to go with a mudder?
How do I know which t-case I have and how can the np205 be identified?
