This is a special order product please contact us for lead times. 

STEP2

Features Specially designed cam for Step 2 has a duration of 264°, valve lift 8.7mm. Acceleration at high rpm is smoother than solid Step 1 camshaft (272IN-272EX). Step 2 is suited to the higher power output at all ranges of engine rpm. Strength is enhanced when used with upgraded Valve Springs at high RPM (recommended limit 8500rpm). Engine output and torque are substantially improved at all engine RPM range compared to solid Step 1 (272IN/EX). Step 2 was designed to show significant power and torque improvement for vehicles tuned to output 600ps or higher compared to old type Step 1 type B (256EX).
