SHAFT KIT, REAR AXLE, NEW, (2) 5 LUG, 30.625 INCHES LONG, 31 SPLINE, 4340 CHROMOLY CONTENT, THESE UNITS ARE 40 PERCENT STRONGER THAN STOCK, REPRO
These performance rear axle kits are made from high tensile strength 4340 Chromoly that contains significantly more manganese than 1040 steel found in your stock axles. This increases ductility and translates the ability to absorb stresses. They are then heat-treated, tempered and induction hardened to produce these heavy-duty axles that are up to 40% stronger. They use the latest cold spline rolling technology to produce splines that are stronger than traditional cut splines. The shafts are then precision CNC machined and magnaflux inspected for cracks before receiving a slick black anodized or natural finish. Our rear axle shaft kits include everything you need for your installation: both passenger and drive side shafts, seals, bearings and wheel studs./P>
28 spline units are designed to be used with stock differential units. 31 spline units require a different differential unit the excepts 31 spline axle shaft.
