Nitro Gear & Axle now offers an assortment of Heavy Duty Cut-to-Length (CTL) rear axle shafts. The CTL axle shafts feature extra Long splines and can easily be cut to the desired length with a chop saw. This allows Nitro to use stronger rolled splines rather than cut splines and allows fewer part numbers to cover a wide range of OE and custom Fits. This also makes it easier for Offroad, restoration, and Rod Shops to stock axles since they fit so many Fits.

Nitro Gear & Axle strives to provide the highest quality differential & axle components available. We take the steps necessary to ensure our parts are dependable. Our product range is continually growing to meet the needs of consumers for new ratios and Fits. At Nitro, we know differentials and know what it takes to provide you with high quality components.

  • Trim to desired length.
  • Nitro axles are heat treated after splines are cut. Most custom axles have the splines cut after heat treating, removing heat treated metal from the spline section of the shaft.
  • Triple-drilled wheel pattern to fit a wide variety of applications.
  • Eliminates the cost and need for custom Axles!
