Gear/ Carrier Set up
Posted: October 13th, 2021, 5:37 am
Hello all,
I have seen many suggestions on gear set up and I am at a cross roads to make a decision. First here is the build I'm working on.
Frame off restoration 1980 CJ7 - I bought this not running so I have never driven it before to know its characteristics.
1980 CJ7 Renegade
3.08 gears
Building 4.6L Stroker with T176 4sp trans, Dana 300 transfer
Dana 30 front(narrow) AMC20 rear (narrow)
2-2.5" lift
31' tires (would like to stay 31's but if the lift is too much and I need to fill in the wheel wells a bit I would be open to go 32's or 33's)
Any opinion on tire size to lift?
This is fun weekend Jeep that will mostly cruise around town, camping, beach driving ( some highway driving to get to destinations) and would like it set up so my wife and kids will enjoy driving it as well.
All charts point to run 3.73 - 4.11 gearing however the break point of having to switch the front carrier is 3.54.
1) With the added power and torque with the stroker would 3.54 ratio be sufficient with 31's?
2)What is I need to go up to 32 or 33's -
3) if I need to switch carriers is it a straight swap that I can just get a 3.73 and up case and switch internals?
4) is there a different carrier or locker that I should look into based on my application
Thanks for your input, Unfortunately I was not able to drive it prior to know the characteristics so I would like to hear personal experiences.
Thanks,
Kevin
