CNC-Machined from billet
aluminum, our two-piece rocker box is innovative in design and function.
Rocker stanchions are machined integrally into the rocker box for added
strength, and not as a separate piece. Functionally, we’ve reengineered
the way oil separates from the air and air flows out from the engine.
The end result: easier air movement separates the air from the oil more
efficiently and nearly eliminates oil carryover into the air filter.
This rocker box has a sleek appearance and compliments any top end. The
two-piece wedge design allows far easier access to internal parts for
service and maintenance. Extra wall thickness reduces noise and adds
stability, reliability. Chromed to a mirror finish. A huge upgrade from
stock rocker boxes – now available on all TP Pro-Series® engines,
and sold separately. Includes rocker shafts and all necessary hardware
for easy installation. Pro-Vent rocker boxes will fit Evolution®,
big twin®, Sportster®, and Twin Cam engines.
