2003 88ci Heritage Softail – Feuling 525 Cams
DYNO RESULTS
A nice bolt in cam for a 88ci. This is one of the largest “bolt in” cams available for Twin Cam 1999-2004 models.
Its gave a nice increase in Horsepower & Torque across the board from 2250rpm. Definitely a worthwhile investment while also getting rid of the OEM spring loaded cam chain tensioners.
These are prone to failure & upon failing destroy your engine 90% of the time. We used the Feuling OE+ Hydraulic Cam Chain Tensioner Plate Upgrade Kit to eliminate the OEM spring loaded cam chain tensioners
