Shifter Carrier Front Mount Bush for BMW E46 M3 - PFF5-4631

Dial in a tighter, more connected gear change on your BMW E46 M3 with this premium front mount bush for the shift carrier, part number PFF5-4631. Manufactured in durable performance polyurethane, this selector support insert replaces the soft factory rubber to cut unwanted movement in the transmission linkage and deliver a crisp, positive shift feel.

We fit these in-house at MJ Modifications and the feedback is consistently excellent. Customers report a more accurate gate selection, reduced slop at the lever and a reassuring, direct engagement without harshness. If your gear change feels vague or rubbery, this is a simple upgrade that transforms driving confidence on road and track.
