I'm hoping to get the collective advice from all the talented people building sweet rigs. Here are my plans:
Questions about the Atlas:
Questions about Chassis:
Examples from other Mud members of end results:
(apologizes for not @ mentioning the owner, only pulled pictures while researching):
- FJ40 aluminum tub extended 18 inches by Aqualu
- Primary use case is rock crawling with the ability to drive 4+ hours
- Four Seasons (heat & AC) vehicle with modified extended Hard Top
- Targeting wheelbase of 112 inches to 115 inches
- 3-link front and double triangulated 4-link rear
- Atlas 4 or 2 speed transfer case
- Dana Ultimate D60 Front axle with with ARB Locker
14-bolt Rear axle shaved with ARB Locker - Connect&Cruise LS motor with 6L80-E
- 40 to 42 inch tires
Questions about the Atlas:
- I was planning a 4 speed, but I was recommended to leverage a 2 speed due to the amount of power from the LS V8
- Assuming the 2 speed is a better approach, which is 3.0:1 vs 3.8:1 ratios?
- The gearing spread is capable 6.04 with the 6l80-E, with ratios in each gear as follows:
- First: 4.02, Second: 2.36, Third: 1.53, Fourth: 1.15, Fifth: .085, Sixth: 0.67
- Regarding the Axle gearing, I was thinking about 5:13 gears
- Of course, 4:88 gears are another option.
Questions about Chassis:
- Came across the Bustled Knuckle lower chassis and thought this might be a nice base to build from
- This approach handles some of the suspension engineering required
- Of course, would need to figure out how to mount the tub
- Anything I'm missing going down this approach?
