All Dynatrac axle assemblies are made in the USA with the finest USA made materials, forgings, machining, welding and assembly. Dynatrac set the standards for custom axle performance and now with a wide selection to fit every application and budget.

All Dynatrac axle assemblies are built from the finest materials and components available, with quality-control checks at 115 points. Hardware is US-sourced Grade 8, with thread locker used on all housing fasteners. Gears are genuine Dana/Spicer or Precision Gear. Dynatrac axle tubes, housings and knuckles are machined to ultra-precise tolerances joined on a special 100-ton press, and heliarc welded for superior strength and longevity. All housings are deburred by hand, painted inside and out, given a smooth finish from housing to axle (for oil flow) and housing bores are fully blueprinted.
