SBC SB Chevy Steel Roller Rocker Arms 1.60 3/8 Vortec

Full set (16) of small block Chevy 1.60 ratio 3/8" stud mounted 4340 steel roller rocker arms and nuts. Self aligning. Tip is guided by the rocker arm itself, not a grooved roller which can chip or break. 

A definite improvement over stock rockers, these steel roller tip rockers are made from 4340 heat treated steel, and feature a longer slot design to eliminate stud interference. Unique nut is self locking, this design allows clearance under most all stock style covers unlike bulky tall locks. Grooved ball for better oil lubrication! 

Excellent replacement for stock or sportsman engines. It will fit most all small block Chevy stock and aftermarket 23 degree cylinder heads.  Can add up to 30HP over stock rockers. These rocker arms are far superior to Speed Pro or Elgin rocker arms.
