ProRock 44/60 Hybrid™

ProRock 44/60 Hybrid™


The Dynatrac ProRock44/60 Hybrid™ offers all of the advantages of the ProRock 44™ plus the advantage of Dynatrac Pro60® axleshafts, knuckles, fixed spindles, 1480 steering joints and hubs. This provides the unbeatable ground clearance of a Dynatrac ProRock 44 and the axleshaft and outer-end strength of a ProRock 60! Add the strength of a Dynatrac Pro 60 at the ends of an ultra-high ground clearance ProRock 44. Dynatrac JK axles include exclusively designed ABS and stability control sensor mounts to maintain all factory function of these systems.

ProRock 44/60 axles are available with either Warn or optional Dynatrac DynaLoc™ locking hubs. When you use the Dynaloc locking hubs with our exclusive Stub Hub kit, the overall package is 4.75-inches narrower. That means that the hubs tuck into the wheels better with 2.388-inches per side.
