Gun Drilled Short Track Axles Oval track axles are manufactured from ultra-high-strength alloy steel for outstanding yield and tensile strength. CNC-hobbed splines provide precise tolerances and even torque transfer, and are heat-treated, shot-peened, and REM finished to increase durability. Axles are gun-drilled .578" to reduce rotating weight.THE KERA CONCEPT AND PROPER AXLE SELECTION
Although the left and right axles are different lengths, they are typically the same diameter, and therein inherently lies the problem. Because that the right axle is longer, it has a lower spring rate than the left. The result is that left axle does not “wrap-up” as great as the right and the car has a tendency to steer right on initial acceleration because the left rear sees the power first. By simply using a smaller diameter left rear axle with the KERA (“Kleban Equal Response Axles”) split diameter concept (also referred to as wrap axle), torque steer reaction can be equalized under both acceleration and deceleration. By referring to the accompanying chart, you can determine the proper axle diameter for the right and left side.
Ultra high strength low alloy steel offers outstanding yield and tensile strengths, fatigue properties, and high toughness
Vertical rack heat treating controls distortion
CNC hobbed splines tightly controls tolerances for even torque transfer and consistent misalignment angle of drive flanges
Generous transition fillet radii essential to reduction of stress risers
Additional attention directed to non-aggressive machining to impart a minimum amount of residual tensile stress
Shot peening provides increased torsional and bending fatigue life with the application of residual compressive stress
Isotropic superfinishing reduces spline wear, lowers operating temperature, and minimizes micro stress risersProduct Description: Axle Shaft, 30-1/2 in Long, 31 Spline Carrier, 24 Spline Drive Flange, Gun Drilled, Steel, NaturalPit Stop USA offers Strange Oval Gundrilled Axle - 31 Spline - 30.5" - 1.080" OD AGY10803050 at low everyday prices.
