Pro Rock Series Differential Covers
Dynatrac Pro-Series Differential Covers offer top-notch protection for your axle’s differential. Cast from Dynatrac’s own proprietary, nodular iron, Pro-Series Covers provide not only excellent differential protection and unrivaled strength, but also enhance the look of your undercarriage.
Axle Shafts
Stock (OEM) axle shafts are made from 1039 alloy material and are induction hardened forming a hard shell around the soft core of the shaft. For stock applications this type of shaft is very durable. When moving up to larger tires and more horsepower the OEM alloy is not strong enough and tends to twist and fail when the yield strength is reached or exceeded. Dynatrac uses one piece forgings made from case hardened 1541-H material. This process results in a hard case axle with a soft core, but still stronger than the stock alloy, that enables the shaft to bend, flex and spring back when a stock shaft would have failed. This creates an axle that will hold up to the toughest of situations.
