BUILT TRANSMISSIONS TO
HANDLE THE POWER YOU WANT

Welcome to Clarke Transmissions

Looking for a custom transmission for your Focus RS, Focus ST, or Fiesta ST? Clarke Transmissions build the smoothest and strongest transmissions you can buy. Drive your Focus with the grip you’ve been looking for and built to handle all the power you can throw at it.

All transmissions are completely disassembled. Every gear and receiving gear synchro gets inspected and meticulously deburred to eliminate any casting flaws, ensuring the smoothest engagement possible. Then, the entire gear set is sent out for WPC treatment. Upon return, all synchros are replaced with upgraded carbon synchros, all bearings are replaced with upgraded caged bearings, and gear sets are reassembled. All operation and engagements are checked before installation into a freshly cleaned, hot tanked transmission case with your choice of differential; Wavetrac, Quaife, or MFactory (MFactory for ST model Focus only).

The Smoothest & Toughest RS / ST Transmissions.
