SuperATV Rhino 2.0 Axles: Design, Fitment and Real-World Builds

SuperATV Rhino 2.0 Axle

SuperATV Rhino 2.0 axles are heavy-duty replacement CV axles designed for UTV owners who need an alternative to the factory driveline. Introduced in 2017, the Rhino 2.0 line combines heat-treated 4340 chromoly steel, larger shafts and CV joints designed to operate at substantial suspension angles. SuperATV offers vehicle-specific versions for a wide range of machines, including standard-length and selected long-travel applications.

Axle selection matters most when a UTV has larger tires, a lift, portal gear boxes or suspension changes that increase the demands on its CV joints. The correct axle depends on the exact vehicle and suspension configuration; a stock-length Rhino 2.0 axle and one supplied for a long-travel kit are not interchangeable simply because they share the Rhino 2.0 name.

How Rhino 2.0 Axles Are Built and Tested

SuperATV uses 4340 chromoly steel and a proprietary heat-treatment process for Rhino 2.0 axles. The company also emphasizes larger shafts and CV joints designed for high articulation angles. These details address two common demands in a modified UTV: transmitting torque through a heavily loaded axle and maintaining CV operation as the suspension moves.

In SuperATV’s Rhino 2.0 development video, Justin explains that its research and development team collects data on axle strength, torsion and endurance using in-house test equipment. He says the team has also tested hundreds of competing axles. Keeping project managers and engineers together allows SuperATV to use those results during product development.

SuperATV says it designed the Rhino 2.0 CV joints for applications ranging from high-speed desert travel to rock crawling and trail riding. Justin also describes resistance to CV heat buildup as a development goal. The video explains the company’s design approach; it does not provide test results that establish how every Rhino 2.0 application compares with a stock or competing axle.

When Rhino 2.0 launched, SuperATV advertised the axles as “100% stronger than stock.” That is a manufacturer claim from the original product announcement, not a universal result for every UTV model. Shaft dimensions, axle length and the factory axle used for comparison vary by application. SuperATV’s current product listings commonly describe Rhino 2.0 axles as nearly twice as strong as stock.

Why CV Joint Angle Matters

An axle must transmit power while its CV joints change angle through suspension travel and steering movement. A lift or long-travel suspension can change those operating angles, while larger tires can increase the loads the axle experiences. SuperATV designed Rhino 2.0 CV joints with those applications in mind.

That does not mean an axle can correct an unsuitable suspension setup. Before ordering, check the axle listing against the UTV’s model and year, front or rear position, and any lift, portal or long-travel kit installed. If the vehicle has aftermarket suspension, confirm whether the kit requires its own axle length.

Rhino 2.0 Axles in UTVGuide.net Builds

We have documented Rhino 2.0 axles as part of complete vehicle builds, where they support changes elsewhere in the drivetrain and suspension. Our Stage 2 Kawasaki KRX 1000 build paired them with SuperATV GDP portals, high-clearance trailing arms and 35-inch Maxxis Roxxzilla tires. That setup used the portals for ground clearance and gear reduction while the axles formed part of the supporting driveline.

A Polaris GENERAL rebuild also included Rhino 2.0 axles alongside high-clearance suspension components. For another example of the axle line in a custom vehicle, see SuperATV’s R2S2 tandem-seat Polaris RZR RS1 build.

These examples show where the axles were used; they should not be read as a controlled comparison of axle strength or service life against stock parts.

Warranty and Choosing the Right Axle

SuperATV currently lists an 18-month warranty for Rhino 2.0 axles against manufacturing defects, subject to the terms of its warranty policy. Review those terms and the specific product listing when ordering.

Start with the exact make, model and year of the UTV, then verify the axle position and all suspension changes. Check separately for portal-compatible, lift-kit or long-travel applications. SuperATV’s current axle catalog provides application-specific listings and fitment information.

Where Rhino 2.0 Fits in a UTV Build

Rhino 2.0 remains a relevant axle option for riders upgrading a stock machine or planning a larger suspension and tire package. Its 4340 chromoly construction, larger shafts and high-angle CV design are the central features. The most useful buying decision, though, is choosing the version built for the vehicle’s actual suspension and driveline configuration.
