I'm swapping out my stock 2.73 for a strange engineering 3.73. Besides the ring and pinion I bought a deluxe install kit and rear end cover bolts. Is there any other parts i will need to complete the swap??

 

You should have bought a gear set that would fit a 2 series carrier, since you did not say anything about swapping carriers.

 

ya i did buy a gear that will fit my carrier

 

Need the right tools, including a dial indicator and a pinion depth checker, plus some indicator paste.

 

I was mostly wondering about the speedometer and ABS inop

 

You have to reprogram the correct gear ratio into the PCM. The swap should have no affect at all on ABS, as long as you are using the same carrier you already have. You would only get a ABS INOP light if you damaged the sensor on top of the housing, or switched to a carrier that did not have the reluctor gear in the correct position. This assumes you have only ABS and not TCS.
