Description

Pro Race 40 spline gun drilled axles with 3.150″ axle bearings, & 5/8″ stud kit

After more than 50-years of providing the ultimate drag racing axle, Strange knows what axles to stock for specific applications. Strange Pro Race Axles are made from a steel alloy that was originally intended for use in military aircraft landing gear. Hy-Tuf is in a class of ultra-strength alloys configured with a low concentration of carbon and high degrees of manganese, nickel, and molybdenum steel. Strange 40 Spline Axles are through-hardened to a tensile strength of 240,000 psi allowing them to retain the necessary degree of ductility required for elite level drag racing.

Strange Pro Race 40-Spline gun-drilled axles are ten-percent lighter and 54-percent stronger than 35-spline solid axles. Gun-drilling is a process of removing the core of the axle shaft and leaving a .875-inch hole. Five 1-inch diameter holes are drilled in the axle flange to further reduce rolling mass. Strange 40-Spline gun-drilled axles are rated for vehicles that weigh 3,500-pounds or more and can post quarter-mile elapsed times of less than 7-seconds.

When we developed our 40 spline axles, the bearing surface OD was made to a giant 1.7735”. By using a special stainless steel ring, we were able to accomplish three important goals. Increase the radius of the axle bearing shoulder, drastically reduce stress concentrations, minimize the distance from the bearing shoulder to the outside of the axle flange, and set axle offset to match the brake kit.

Strange offers the choice of two types of 5/8” stud kits. Our traditional A1027 stud kit features premium bolts & adjustable .875” long sleeves. This the lightest stud kit. In addition, we offer five lengths of chrome moly stud kits. Ensure dimension “A” is able to fully engage into your wheel. This needs to be slightly greater than the combined thickness of the disc brake hat or drum and the thickness of the wheel.
