i ran 4.56 with my k 5 blazer and 32 inch tires and it was awsome . stock gears were 3.42 and it was night and day diff . so 4.56 would be great gear choice since you dont need mpgs.

 

bump..

 

Whitedakota, I never changed the gears im actually lowering the truck 3/6 tomorrow and putting the stocks back on with a 275/60/17 and should make a good improvement if it still isnt how i want it to feel than i will do the swap. It can only be beneficial cause our cc are heavy and im never gonna go FI so its still up in the air

 

to make the gear change/$$$ worth it id go 4.56, 488 would be good if your wheel/tire package is near 100lbs

im gonna run 37's with 5.29 maybe 5.43
