Review PEM Performance Engineering Manufacturing 9in Gear Full Spool 5.29 Ratio New Section

Introducing the PEM Performance Engineering CSF52931 9-inch Gear Spool with a 5.29 center, a high-performance upgrade for automotive enthusiasts seeking to enhance their manual transmission system. This gear spool is meticulously designed and manufactured to provide superior power transfer and smoother gear shifts.

The CSF52931 is a drop-in replacement for the stock gear spool in various applications, including but not limited to, Ford Mustang GT, Ford Focus RS, and Volkswagen Golf R.
