Dynamic's REM Polished Input Shaft is a good upgrade on a Street/Strip unit that doesn't require a Hardened unit like our C4 Hardened Input Shaft.
We take select used cores, clean and inspect the splines and have the REM finished.
The result is a stronger than stock piece due to the stress relieving process and better oil flow past the shaft due to the smooth finish.
These are 1971 and up 24/26 spline shafts.
