Axle Tubes
Axle tubes are the housings that the rear axle shaft runs through, forming the structural backbone of the rear end on circle track and oval racing cars. This range includes aluminium and steel tubes in various lengths and diameters, along with related hardware like tube seals, spindles and big bearing axle snouts.
Tube choice comes down to length, diameter and material. DMI's Smarttube axles come in specific lengths like 24.018", 26.018", 30.060" and 32.00", while Winters offers both aluminium (2-7/8" diameter) and steel big bearing tubes in various lengths to suit different chassis setups. Aluminium tubes save weight, steel tubes are generally tougher under impact.
When selecting, match the tube length and diameter to your existing rear end housing, and check whether your car runs a big bearing or standard setup before choosing bearings, seals or snouts to go with it.
Frequently asked questions
How do I choose between aluminium and steel axle tubes?
Aluminium tubes are lighter, which helps with overall car weight, while steel tubes generally handle impact better, so the choice depends on your priorities and class rules.
What length axle tube do I need?
Measure your current housing or check your chassis specs, as tubes come in set lengths like 24", 26", 30" and 32", and the wrong length won't fit your rear end setup.
What is a big bearing axle tube?
It's a tube sized for a larger bearing and snout combination, often used for extra strength in higher load racing applications, as opposed to a standard bearing setup.
