Lamspeed Racing Mitsubishi Evolution 4-9 Under Drive Alternator Pulley

Details:

Designed and manufactured in Australia from 6061 billet aluminium. These under drive pulleys are designed to under drive the alternator by 14%. Used in some of Australia's fastest evos. In race conditions we have found that the OEM sized pulley was causing alternators to over spin that lead to the internal regulator failing. With this under drive pulley it has been designed to be a larger pulley to slow down the alternator rpm.

When fitted, you must take this to your tuner to adjust the engine idle RPM.
