I am considering getting a procomp lift and have noticed some lifts require the front axle shaft to be notched and rebalanced. Do you have to do this with the procomp lift also. Also, I can drive at city speeds now in 4wd when its wet, will I still be able to do this after lift?
Thanks for any replies.

 

Why do you drive in 4hi on wet roads? You running slicks?

 

x2 thats alot of abuse on the 4wd system

 

I didn't have to do anything to my drvieshafts. 4lo and 5 hi still work the same but I never use them unless I need them.

 

My lift didn't require me to modify the drive shafts in any manner.

As for 4-hi operation at speed: Yes, you can still run in 4-hi. I have shifted into 4-hi at 45mph just to make sure it worked properly, and ran it up to 50mph in 4- hi with no problems or vibrations. Snow is about the only time I will use 4-hi at decent speeds, but that is rare.

 

Might depend on the truck possibly - my driveshaft needed to be clocked and re-balanced. After I installed my lift, I went to Colorado to go skiing - just snowed and when in 4x4 high there was a bad vibration at 50+ mph. When I got back home I had the driveshaft clocked and rebalanced at a driveline shop for $65 and now it is perfect. I can go 50-60 mph and no more vibration. So try it out first - if it vibrates - get the shaft modified. Don't need to lengthen it - just put it back 'in-phase' and balanced. The specific directions can be found on the Fabtech's website in the lift instructions.
