33" with 4.11 should I feel any powerloss?

hi, i live in mexico and im new to jeeps a year ago i bught my first jeep, wich is a bone stock 2000 tj 6cil with freshly rebuild 32rh tranny with 3.07 gears and 235/75r15 goodyear wrangler. After a year of dreaming im ready to make the firt mods to my jeep, i have 2 2006 dana 44 rubicon axles with 4.11 gears ready to go in, with a NP241OR transfer. my question is should i notice any loss in throttle response when i put 33" tires with the 4.11 ? or should i go with 32 for more power.

The 4.0L with the 32RH coupled with 4.11 gears on 33" tires is the best optimal setup.

Your rpm's will be a little higher than stock. Right now, you should be turning somewhere around 2500 RPM at 70 MPH. With 33's and 4.11's, you will be at roughly 3k. Your final drive ratio currently is 16.89 (in 4lo), with 4.11's it will be 22.61.

Not to hijack this thread, but in another thread people were telling me to go with 4.10's and I only have 31" tires?

You have a different transmission.

Note that the OP has the 32RH. This is a 3 speed auto with the highest gear having a 1:1 ratio.

You have an AX-15 according to your profile. This is a 5 speed manual with an overdrive gear.

Since you have an overdrive gear and the OP doesn't, you would want deeper gearing relative to the tire size than them.

Just for comparison that's roughly what I'm running with 3.73 and 31's... Works pretty well
