Thru-Hardened Axles (ProRace)
Stranges ProRace series of axles are constructed from Hy-Tuf steel,
a high nickel, ultra-strength steel alloy originally developed for military
use. Axle forgings are machined to required specifications then heat treated
in a vertical furnace to achieve a uniform hardness level from surface
through to the center of the shaft. Because of their Thru-Hardened quality
these axles while torsionally superior to withstand the abusive nature
of drag racing, are not suited for high bending loads common with everyday
street use. ProRace axles feature precisely machined 1.5635 bearing
and special radius ring seat. The press-fit radius ring minimizes stress
concentrations along the bearing shoulder and improves axle flange stability.
Raised brake registers are machined to size based on your particular brake
and wheel requirements.Kits come with everything needed for a complete
axle installation into your new aftermarket or existing factory housing
