LROR's Silverback HD 4140 Chromoly Axles for the Toyota Pickup / 4Runner are like the name implies- Strong! These are made from high grade heat treated 4140 chromoly steel. Many axles have their drawbacks by poor design and large stress risers. Not here! These are made for heavy duty usage and for off road ability. Also highly recommended when installing a Spartan, Lockrite, ARB, Grizzly, Zip, Auburn, Eaton, Aussie or Kaiser Locker.
-Heat Treated 4140 Chromoly. Why not 4340? It has been used in the past on Rear Axles and has proven to be weak. For the fatigue resistance and characteristics of 4140, we chose to manufacture them out of what has proven to be the strongest! Some large name manufacturers have scaled back to 4140 and had less breakages than with 4340. We could have made them out of whatever we wanted, but these have proven to be the strongest!
-30 Spline Shaft for easy installation into your factory spider gears or into an aftermarket locker.
-Uses factory rear wheel bearings and seals as well as factory axle studs for ease of installation and cost effective installation.
-Black Oxide Coated for Corrosion Resistance.
