TeraFlex CRD60 axles are the original Jeep specific off road axle - we set the industry standard in 2002 and have never looked back. The CRD60 introduced off road specific solutions and revolutionary axle technology that has become an industry standard. Unique features such as a rotated cover line, smooth high clearance surfaces, integrated suspension mounting points, oversized bearings, and increased oil flow were specific areas of needed change that TeraFlex introduced to the off road industry. These advancements have since been assimilated by the off road industry. Over the years TeraFlex has proven to be at the forefront of innovation, becoming the most respected industry leader. The CRD60 has been engineered and designed for maximize protection, performance and durability. The Tera CRD60 provides an integrated top mounting pad reinforced for 4-link suspension. The exclusive Constant Radius Design provides high ground clearance that is unaffected by pinion angle adjustments. Increased rib gussets strengthen the housing to eliminate deflection under high load, heavy duty bearing caps also help to increase rigidity through the bearings and carrier to reduce ring and pinion distortion. The CRD60 has a built in skimmer that cuts the ring gear oil halo and forces oil into the pinion bearings. The CRD60s front pinion bearing pocket has a renewable oil reservoir that replenishes as you drive and keeps a fresh reserve of oil that constantly bathes the pinion bearing in cooled oil. The high capacity housing acccomodates over 3 quarts of gear oil ensuring operation for extended highway driving. An oversized front pinion bearing is designed to easily handle the increased torque conditions resulting from high load conditions. As part of the hand-built axle production process, axle tubes are machined for a precise interference fit prior to being pressed into the housing. All 1/4" axle brackets are located in jig fixtures to ensure correct suspension mounting to maintain factory suspension geometry. They are then welded in place by certified in house TeraFlex crafstmen. The preparation process prior to final coating involves a surface hardening media blasting to remove all oils and contaminats, a chemical etching process and a Premium UV protected triple-stage powder coat to keep the axle resistant from all environmental conditions. TeraFlex CRD60 axles feature a 1 year unimilted mileage warranty against defects.
