Drive Damper - Ford Super-Duty

This damper is designed for the Ford 351W engines that have been modified to 285-350 HP It has the same (8) Purple Spring core as our HD Chevy Damper but  is a smaller diameter for the small Ford Flywheels.

Uses (3) bolts to secure to the flywheel always use locktite on these threads.

WILL NOT WORK with the PCM 40 transmissions with the little 15 tooth input shaft.

USE LockTite on the bolt threads! 

Strange rattling, metalic sounds coming the the back of your engine, worse at idle, high eng. hours?? This is typically from the drive damper going bad. 

Replacement Notes: Remove exhaust near trans, remove trans mount bolts to boat & drive-shaft coupling, loosen front pinion bolts & WD-40 pinion. Hoist rear eng. w/trans, remove trans, remove bellhousing, remove drive plate. Carefully choose bolt holes in new damper, attach with same bolts (Typically only 3 bolts used, original may have had 6) USE LOCKTITE on threads. reinstall bell-housing, apply spline grease, trans should slide easily into drive if bolted up correctly. Put back together.
