EXACT REPRO ROCKER ARMS – Clark’s Rocker Arms are the Only Correct
Rocker Arms Available (all others are simply small block Chevy). We spent over $1000 to have
an accurate CMM (coordinate measuring machine) engineering print made. It took 100’s of 3
dimensional measurements & angles for production. Several styles were used by Chevy over the
years. Larry Claypool said he feels this later style is the best.
17, 18 & 19. Rocker Arm, Pivot Ball & Nut Set
The rocker and/or balls tend to gall and wear. Each Set has 1 rocker, 1 ball and 1 nut. Order 12 for a whole engine.
MATED SETS with GROOVED BALLS ARE THE ULTIMATE! Pre-seated for quick break in – See page 27C for more info.
PLAIN BALL STYLE: These Sets have a plain (original style) rocker ball.
GROOVED BALL STYLE: These Sets have a grooved rocker ball which allows for better lubrication of ball and rocker.
