Steel or aluminum driveshaft for your swap? The aluminum is both stronger and lighter — here is why, what wall thickness has to do with it, where driveshafts actually fail, and why rotating mass matters more than the pounds suggest.
The CD009 comes with 90mm, 95mm or 100mm input shaft bearings, and every ASE adapter plate is cut for 100mm. Installing against a smaller bearing causes radial play that destroys the input shaft bearing and the pilot bushing adapter — here is how the included laser cut bearing rings fix it.
Step-by-step installation of the ASE CD009 to JZ adapter plate — seal installation using the pilot bushing, gasket and Permatex method, bolt lengths and torque specs, slave cylinder ordering, and J3 bell housing notching. Also clears up the long-running myths about cutting the spud and the input shaft tip.
