since its an ls truck and 3.23....do i just buy a motive 4.10 gear set and isntall kit? or should i invest in anything else? rear end shop by here says around 300 to install the gears and ive seen the motive deals around 150 online.

 

pm axist6 he does a lot of rear ends, and every body has been very pleased with the service. i went from 3:42 to 4:10. much more driveable in city, picked up 1 mpg. i havent even tried to average mpg on highway because i might wanna take em back out as far as sotp difference, i dropped .5 seconds going to the 4:10's

 

should i worry about limited slip or posi? or just throw in some geras? i wont be racing or anything.

 

you should since you are already in there. i would throw in a posi if it were me.
