Spicer AdvanTEK differential assemblies have demonstrated themselves extremely reliable on trucks running stock tire sizes devoid of any upgraded power output. Most of these Spicer AdvanTEK differentials came equipped from the factory with a 3.31 ratio, projected to have a proper run out with a stock size tire, 32"/275-65R-18 size. If considering upgrading to a 37" or larger tire, there will be an RPM vs. speed confliction, generating a disruption of the shift pattern on trucks equipped with an automatic transmission. Aimed at those individuals that mandate the considerable need for power increases and larger tires, there is an opportunity for enhancement to improve the dependability and performance that is affordable. Look no further, one of the best improvements we can endorse for that increased tire size is that of a Nitro ring and pinion ratio upgrade.
