Dana Adds Ratios to Spicer® Ring and Pinion Gear Offerings for Dana 44 and Dana 60 Models

Dana Holding Corporation (NYSE: DAN) announced today it has expanded its Spicer® ring and pinion gear options for Dana 44TM (226 mm) and Dana 60TM (248mm) rear axles to include additional ratios, while ensuring top-of-the-line part quality through the manufacturing processes.

New ratios available for the Dana 44 and 60 axles include 4.56, 4.88, and 5.13, adding to existing ratios of the Dana 60 axle that range from 3.54 to 7.17 and the Dana 44 axle that range from 3.07 to 5.13. 

“By incorporating a thorough, innovative manufacturing process to develop our gears, we are able to offer a level of quality that is unmatched by other suppliers producing gearing technologies,” said Bill Gryzenia, vice president and general manager of the Dana Aftermarket.  “In addition to maintaining a supply of reliable, genuine quality products, we are developing additional ratios to better meet our customer demands.”

Dana engineers its precision-machined 3-axis gearing technologies in the U.S., using controlled processes that include heat treatment, face hobbing, shot peening, lapping, and a special coating for initial break-in.  Heat treatment enables Dana to secure optimal hardness of the steel used, while face hobbing accurately cuts the gears to achieve desired spacing between gear teeth, reducing noise, vibration, and harshness and ensuring a quieter ride.  Shot peening maximizes durability and strength, nearly doubling the life of non-genuine parts, while lapping creates an improved contact pattern.

Based on customer feedback, Dana has created a new Spicer® gearing kit option to include the ring and pinion only for these applications.

Dana also is offering customers its Spicer® differential bearing kits that come with the necessary components to complete the installation.  Parts included in the differential bearing kits can repair vehicles that are equipped with Dana 30, 35, 44, 60, 70 and 80 axles.

The Dana 60 axle is a premiere choice for off-roading vehicles, towing applications, rock crawlers, and street rods.  Similarly, the Dana 44 axle is consistently used in off-road, four-wheel drive, street, and strip applications.

Dana is featuring its expanded options during the nine-day 2013 Easter Jeep Safari, March 23-31 in Moab, Utah.  It is America’s largest and best-known annual event that promotes recreational four wheeling over 30 different trails.
