Spicer axle shafts now available from Dana

chromolySpicer high-performance chromoly axle shafts – optimized for use with larger tires – have been introduced by Dana Holding Corporation.

The new Spicer chromoly axle shafts are manufactured using SAE-4340 nickel chromoly steel for maximum strength and durability and are heat treated to ensure optimal hardness throughout, the company says.

“We’ve designed these axle shafts to exceed OE standards and meet the extreme demands of off-road use,” says Bill Gryzenia, vice president and general manager, Dana Aftermarket. “Not all chromoly axle shafts are alike. Spicer chromoly axle shafts have been engineered to deliver added strength and durability and are another example of the precision engineering and manufacturing expertise Dana brings to performance applications.”

Dana says the Spicer axle shafts are made entirely from SAE-4340 nickel chromoly steel for ideal hardness throughout the structure. Dana says the nickel provides additional toughness, while the chromium ensures high-temperature strength and resistance to abrasion. Dana also adds molybdenum to maintain a specified hardenability.

Heat treatment processes developed for the Spicer chromolyaxle shafts are designed to increase core hardness to precise levels, while at the same time optimizing case and surface hardness, to achieve maximum impact strength and durability, the company says.
