LEROY DIESEL 6.5 CHEVROLET DIESEL – TimeKeeper DS4 or DB2 Timing Gear Set.

LEROY DIESEL 6.5 CHEVROLET DIESEL – TimeKeeper DS4 or DB2 Timing Gear Set.

Leroy Diesel TimeKeeper for a DS4 electronic Injection Pump (IP) or a DB2 mechanical IP

DS4 are slightly different in that they require a Reluctor wheel and double hump key in addition to the TimeKeeper gear set so they do cost more than DB2 type.

If you order a DB2 TimeKeeper you will not get/need the reluctor or double hump key so the price is lower.

Increased overall performance.

Keeps your timing rock steady throughout RPM .

MPGs might be improved.

Typically faster engine starts.

Better throttle response. Outlasts a timing chain and should never need replacing under normal conditions

These are quite gears and do not make the sound of a loud gear whine witch would get old very quickly.

NOTE: Be sure to soak the two smallest gears in oil for at least and hour prior to installing them. They cannot be run dry.
