A must for servicing valve springs, retainers, and valve seals, our specially made tools easily remove valve springs—even while they’re on the engine and still in the vehicle. The compressors are made from premium heat- treated steel for a long service life.

They feature heat-treated CNC-machined bodies plus premium needle- bearing fulcrums and roller tips that reduce wear and tear on valve stem tips for improved component life and increased horsepower. Machined reliefs improve valve spring clearance. The rocker arms are excellent for use with Trick Flow heads but can also be used on most factory and other aftermarket heads, too. Trick Flow roller rockers are sold in sets of 16 and come complete with polylocks.
