24 Axles 28 Spline Pair for 930 CV Joints

OVERVIEW

When you are pushing the limits of your off-road machine, whether it is a high-horsepower sand rail or a long-travel Baja Bug, the weak link in your drivetrain is often the factory-style axles. These EMPI 24-inch chromoly axles are engineered to bridge the gap between standard performance and extreme durability. Crafted from high-strength 4340 chromoly steel and finished with a protective zinc plating, these axles are designed to withstand the violent torque loads and extreme angles associated with 930 CV joints. By upgrading to a 28-spline configuration, you are moving into the realm of professional-grade drivetrain components that are trusted by desert racers and weekend warriors alike. The 24-inch length is a specific standard for wide-track or mid-engine configurations where extra width is required to achieve the suspension travel necessary for soaking up big whoops and technical terrain.

Precision is everything when it comes to driveline harmonics and longevity. These axles feature 2-1/2 inches of spline length on each end, providing ample engagement for your 930 CV joints even during maximum suspension extension. The zinc plating isn''t just for looks; it provides a critical layer of corrosion resistance against the harsh environments of the dunes and the trail, ensuring that your splines don''t seize and your axle shafts remain structurally sound for years to come. Sold as a matched pair, these axles ensure that your rear end is balanced and ready for the dirt. If you are tired of snapping stock-diameter shafts or stripping out inferior splines, these 28-spline chromoly units from Appletree Automotive are the robust solution you have been searching for to keep your air-cooled powerhouse moving forward.

PRO TIPS

1. Verify Your Axle Float: When installing 24-inch axles, it is absolutely critical to check for "axle float" at both full compression and full extension of your suspension. You must ensure that the axle does not "bottom out" inside the CV joints, as this will result in immediate failure of the transaxle or the wheel bearing housing. With the vehicle on stands and the springs removed, cycle the suspension through its entire range of motion and verify that you have at least 1/4 inch of lateral play in the axle at all times. If the axle becomes tight, you may need to adjust your stop or check your arm dimensions.

2. Proper CV Joint Lubrication: Since these axles are designed for 930 CV joints, you are likely dealing with high-angle operation. Do not skimp on grease. Use a high-quality, high-molybdenum (moly) content grease specifically designed for off-road CV joints. When assembling, ensure that you pack the grease into the cage and around the balls thoroughly. Avoid "over-packing" the boot itself, as excessive grease in the boot can cause it to expand and fail at high speeds due to centrifugal force. Focus the lubrication where the metal-on-metal contact occurs.

3. Spline Maintenance and Inspection: Before sliding your 930 CV joints onto these chromoly splines, always apply a light coat of anti-seize or assembly lube to the splines. This prevents the CV from "cold welding" or seizing to the axle over time due to heat and pressure. Additionally, during your off-season teardown, always inspect the splines for any signs of "twisting" or "stepping." While chromoly is incredibly strong, it is designed to twist slightly to absorb shock. If you notice the splines are no longer straight, it is time to replace the axles before they fail on the trail.
