Steering the Beast: Why Hydraulic Assist Demands a Dana 60 High Steer Upgrade If you’ve moved up to 40-inch tires and added a hydraulic assist ram to your rig, you’ve likely realized that your steering box is no longer the only thing doing the heavy lifting. While hydro-assist provides the "muscle" to turn those massive tires in a bind, it also introduces a massive amount of lateral force to your knuckles and steering linkages—force that factory components were never designed to handle. To keep your front end from folding under the pressure, a professional-grade Dana 60 crossover steering kit is the essential foundation for any hydraulic-assisted system. The Physics of Pressure: Why Hydro-Assist Breaks Cast Arms Hydraulic assist rams are incredibly powerful. When that cylinder extends or retracts to force your tires over a ledge, it applies hundreds of pounds of direct pressure to your steering arm. The Weakness of Factory Cast Iron Most factory and entry-level aftermarket arms are made from cast iron. While cast is fine for standard steering, it is brittle. Under the "push-pull" stress of a hydraulic ram, cast arms can develop micro-fractures and eventually snap without warning. By upgrading to 1.25 inch thick Dana 60 billet arms, you are moving to a material with much higher tensile strength and zero flex. These Dana 60 billet steering arms are CNC-machined from solid domestic billet blocks, ensuring that every ounce of hydraulic pressure is turned into steering movement, not arm deflection. Bulletproofing the Kingpin Pivot A hydraulic ram doesn't just stress the arm; it exerts a massive "prying" force on the kingpin itself. The factory design uses a nylon or plastic cone bushing that acts as the pivot point. Why You Need Dana 60 Kingpin Bronze Bushings Under the combined weight of a heavy rig and the force of a hydraulic ram, those plastic bushings compress and melt. This creates "slop" in the knuckle, which leads to wandering and death wobble. To build a truly fail-safe system, replacing the plastic with Dana 60 kingpin bronze bushings is mandatory. Bronze is incompressible and self-lubricating. The Kingpin bronze bushing set hardware ensures that your knuckles rotate smoothly and stay perfectly vertical, even when the hydro-assist is pushing at max capacity. Maximum Retention: The 5-Hole Mounting Advantage The most common failure point on hydro-assist rigs isn't the arm snapping—it's the mounting studs shearing off the knuckle. Standard 4-hole patterns often struggle to distribute the sheer force of a hydraulic ram. Reid Compatible Dana 60 Arms For the ultimate in trail security, the East West Offroad Dana 60 arms feature a 5 hole pattern Dana 60 steering arms configuration. These are fully Reid compatible Dana 60 arms, allowing you to utilize a fifth mounting point for significantly increased shear strength. The system is locked down with ten 1/2 inch fine thread studs Dana 60 and Dana 60 tapered nuts. The taper creates a mechanical wedge fit, ensuring that the EWO Dana 60 high steer arm pair remains stationary on the knuckle, preventing the studs from stretching or snapping during high-stress maneuvers. Frequently Asked Questions (FAQs) 1. Is high steer necessary for hydraulic assist? Yes. Crossover and high-steer geometry provide the necessary leverage and clearance to mount a hydraulic cylinder safely. It also ensures the drag link and tie rod are moved out of harm's way. 2. Can I use these arms with my factory 4-hole knuckles? Absolutely. While they are designed as Reid compatible Dana 60 arms to match high-performance aftermarket knuckles, they bolt up perfectly to standard 4-hole factory Kingpin knuckles, providing an immediate strength upgrade. 3. How do bronze bushings handle hydraulic pressure better than plastic? Plastic bushings "squish" under the lateral load of a hydraulic ram. Dana 60 kingpin bronze bushings are solid metal; they do not deform, which keeps your steering tight and prevents the knuckle from shifting out of alignment.
