This is our 33 Spline PRO series Centre Spool Kit, specifically designed for those who are making maximum horsepower and need the largest size halfshafts possible.
Our Billet Half Shafts are made out of the highest grade 4340 Chromoly available on the market today.
Increased in size and increased spline count, when a shaft is subjected to a torque or twisting, a shearing stress is produced in the shaft, the material we use is capable of high stress loads. Capable of over 1,500BHP
We have these available for the 5 Bolt Variant and 6 Bolt GTR Variant.
Please choose the right combination required on checkout.
Our Spool's are developed using 4140 Chromoly Billet Material's and machined to tight tolerances to ensure your wheel's are constantly locked.
Ideal for Drag or Drift application's where equal torque must be applied to both rear wheels , designed for optimum acceleration potential.
These units are less than 5KG in weight, saving weight has many benefits in performance, as less power is required to rotate a lighter mass, meaning faster times on the strip and less wear on your drivetrain.
After manufacturing the Spools, they are then sent off for a Nitriding treatment.
What is Nitriding? A heat treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface. These processes are most commonly used on low-carbon, low-alloy steels. They are also used on medium and high-carbon steels, titanium, aluminium and molybdenum.
