Wheelbase - Posted By kodizzle (kodizzle) on 1st Oct 10 at 11:30pm
Well trying to figure out where i wanna put my wheelbase on the cruiser. The green truck is about 118" and has served me well for as long as i wheeled it open front on the toyota axles. Where is everyone else running theirs at? Just looking for some ideas as well as some Pros and Cons. Smiley

The 113" seemed to be a goal of mine for awhile granted my jeep was like 98" and the blazer was 110" and this chassis i got from Goodby was 113" i am going to stretch it out a little so we will see if i can end up around 115"- 120" leaves me a little room to play with, should be more stable at speeds and climb well, just my .02 cents though

I am at 112", my last rig was at 115".

I think if it is too short you are unstable. But can maneuver around objects, instead of going over them.

If you are too long, it makes turning a lot of work. But makes it very stable.

Overall, whatever suites your needs and wants,

The Rubicon is sittin at a solid 94 righ now, lol I'm looking forward to the 104 that will be coming soon.......and thats just in the rear. {Wink} What axles are going under the cruiser and how wide? Also what size tire's?

I'm at 115" with my toyota. It will climb almost anything but the downside is it doesn't turn that well. Overall I'm very happy with my wheelbase! I would rather have a few backups and extra turns on the trail and have confidence in being able to climb!

won't turn? what lockers do you run? what about your steering set up?

118. Dig {Wink}

Re: Wheelbase - Posted By matt (matt) on 4th Oct 10 at 8:49am
ARB up front but the rear is welded so it pushes the rig a little. I have full hydro up front for steering but the way I have it set up it doesn't turn to full lock but I think it saves dana 44 shafts and u joints

just for fun I'm going to throw some physics at ya.

The lower the vehicle the longer it acts, as far as climbing stability/potential go.

The heavier the running gear, tires and wheels are... the longer it acts.

for climbing... the further forward the weight is in relation to the centerline of the axle the better it is.

A 90" wheelbase early bronco climbs a lot like a 105" jeep.

Breakover angle is also something that dictates how the rig acts.
49's and a 100" wheelbase is like a stock sami
40's and 130" wheelbase is a fail.

hogan's jeep works great at that wheelbase because he has it slammed to the earth so the sprung weight has much less mechanical advantage to flip the vehicle over than say a 6" taller same rig.

what's the perfect setup for yours? there are a few variables but it all depends on where you put the axles.

Yea you could go 118..... but it would be 'tarded if you moved nothing but the front axle forward or only the rear axle backwards.

im going from 105 to 110, fingers crossed....

Re: Wheelbase - Posted By VERTIGO (vertigo) on 4th Oct 10 at 6:51pm
120 and loving it now that its a little higher and taller meats...

Re: Wheelbase - Posted By kranker (kranker) on 4th Oct 10 at 8:30pm
i think somewhere between 110 and 115 is the ticket. just try to keep it as low as possible {Cool}

Re: Wheelbase - Posted By BigRob (bigrob) on 5th Oct 10 at 11:44am
i am not sure there is a "magic" number due to the fact like weight , tires, width, height, suspension, desert, rocks, belly height... etc.. i could list the possibilities but you get my point and already know where your going to put it anyways...lol {Grin}

Hey im still open to suggestions and more knowledgeable input. I have an idea of where i want to put it but for all i know im pissin in the wind, lol Ive been a leaf spring guy and now im goin to links.

axles are gonna be 60 and 14 bolt
tires - 40-42
engine - TBI 350

trans - thinin th400 or 700r4

still thinkin on the rest


Re: Wheelbase - Posted By Sillyneck (sillyneck) on 5th Oct 10 at 2:37pm
with that recipe between 110 and 120 would be sufficient. closer to 110 w/ 40s... closer to 120 w/ 42s.

unless it's going to be street legal etc.

Re: Wheelbase - Posted By bwhit (bwhit) on 8th Oct 10 at 9:13pm
im 120 and seems to be perfect. Like phil was saying i was 112 with 38's and it was great. I threw 47 on there and it drastically changed the whole rig. Felt like I was in a sami. I was constantly pulling tires off the ground.

and if i remember correctly you are right Kody?

Re: Wheelbase - Posted By kodizzle (kodizzle) on 10th Oct 10 at 9:16pm
Hopefully won't ave to but i was gonne set it up to hacete opption to be streetable if need. Since I dont have a tow rig yet seems i need to have that option intjere but hoping by the time I'm don't wont need to

Re: Wheelbase - Posted By btilton (btilton) on 11th Oct 10 at 4:38pm
i think it really depends on what you plan on doing. i was 104 with a 19 in belly for comps. turned great but huge climbs where sketchy. the new one is 112 with a 21 in belly. a little low for bumping ledges but dont plan on dodging cones. i would try to keep the belly height in mind when setting it up. the longer you make it... the higher it needs to be to not get hung everywhere. i would say 115 and 22 would be ideal for a trail rig.

Re: Wheelbase - Posted By Alotakids! (alotakids) on 12th Oct 10 at 9:03pm
All the coolest guys run 112, 22"belly and 42's. {Grin}

Oh yea, i nice flat belly does'nt hurt either.
