he's not looking at it the way we would, he's looking for better times at the track.

The Hemi will get up into it's sweet spot just a shade faster with the 4.88s, get them...

 

i have 270-70-17

 

I say GO BIG OR GO HOME! 4.88's all the way!

 

he could calculate the final drive ratio to the ground and determine rpms at his average track times now, and what the rpm would be after 4.88...thats all i was thinking

 

gotcha, I was assuming you were going on tire height alone to determine what gears would be needed. As 4x4 owners we would, but he wants to get his rpms up into the sweet spot asap...

 

I think it was the gearvendors sight that said if you go to 4.88's you would probably need to upgrade your axles also. I'm not sure if they meant you definitely needed to or if they're just saying that there will be more strain on them.

 

i forgot to ask. I know the abs speed sensor is on the differential and reads off the ring gear. has anybody had there abs system reprogrammed after there gear swap. If you didnt does your abs kick in early or not at all. how much would it cost to reprogram the system?

 

ya forgot about that lol and hammer i would have hit the pipe sooner but you wouldnt give it back you ol rouge!

 

I had my gears put in a few weeks ago, and didn’t have to have anything adjusted/reprogrammed. Both my speedo and ABS, work perfectly fine. The ABS works the same as it did before I got the gears installed. And my speedo is perfectly accurate (I checked it with a GPS).
