Hello everyone and good day. I know this is a dreadful question that has probably been asked before but here i go any how. What is the difference between a ea82 P\T D\R and a F\T once the P\T has been put into 4wd? Does the P\T have a lower "low range" and which one would be better for an offroad rig?

 

Thanks

The chart is here in about 40 different posts, but yes the P/T has a lower low range, and it's FWD when it's not locked in. The AWD one is always putting power to the rear wheels, typically has a 3.70 gear ratio, but is otherwise the same.

full-time doesn't have a 2WD setting. in a 5-speed, it has a lockable differential. un-locked, they're pretty mediocre. locked, they function identically to the PT4WD setup.

 

the PT4WD trans has a lower lo-range (1.596:1 vs 1.196:1), AND a lower diff ratio (3.9 vs 3.7). so for offroading, the PT4WD is better.

 

 

also, FT4WD D/Rs are quite rare (only in the RX), whereas PT4WD D/Rs are quite common.

 

 

EDIT: oh yea...the chart:

the only time I would recommend the FT4WD, is in something with a 2.2 swap. you'll have the torque to keep the tires spinning, so for 99% of what most people would be using them for, you won't need the extra gearing. and you'll have the extra traction for the street (FWD + EJ22 torque + EA82 suspension = wheelspin!)
