Description

Nitro Gear 220mm/Dana 44 4.88 Ring & Pinion

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.

Nitro Gear & Axle strives to provide the highest quality differential components available. We take the steps necessary to ensure our parts are dependable. Our product range is continually growing to meet the needs of consumers for new ratios and Fits. At Nitro we know differentials, and know what it takes to provide you with high-quality components. Nitro gears are manufactured from 8620 steel gear forgings in the same manufacturing facilities as GM, Dodge, Ford & Toyota. They are precision machined using computer controlled processes, heat treated, CNC triple-lapped and Rockwell tested for hardness. These extra steps ensure excellent fitment, ideal contact pattern and smooth, quiet operation.
