Buying a new JKUR - automatic

1019 Views 7 Replies 7 Participants Last post by  nick_v2
When I select automatic, it changes the axle ratios from 4.10 (default for manual) to 3.73. I can add 4.10 back for some $$ if I chose to. What are your thoughts? Where/when do you think it matters? Which would you do and why?

If you have plans for a moderate build/use up to 35's. Or want more grunt off the line or initial torque for pulling. Go with the 4:10.

If your planning on building 35" or up and want that same performance, save your $$$ because you'll want to re-gear anyway.

Get the 4.10's They will serve you well up to 35's but drive great with the stock 32's. Depending on your style of driving, 3.73's are OK for 35's but not ideal. If you never plan to upgrade tires, the 3.73's are probably good. But never say never. 4.10's give you options and when those stock KMs wear out, you'll be wondering about 33's or even 35's.

Plus, the 4.10 option is about $500 bucks. To regear later will cost you a couple grand.

Thanks - that's what I seem to be getting also (and from reading other threads).

Now onto the many other decisions to make... :drinks:

If it's one thing I learned modifying cars/trucks, it's "Never fear the gear". 4.10's would be perfect as you can always run 35's later.
