We offer a 1.7 rocker arm upgrade for the SRT 10. Many folks have approached me and asked why this will help if the SRT has a 1.7 roller rocker to begin with. For starters, the
rocker arms fall a little short of the 1.7 rating and they do not have a roller tip (only the fulcrum). By changing to a stronger and lighter rocker arm with a better pushrod the valvetrain is much more stable. This adds up to power, about 10hp at the wheels on a SRT. For those of you who want to go all out. Crower is just about to release a shaft mounted rocker arm with a needle bearing tip. Engine dyno tests has found these to be
better than the T&D's (which need some work to fit a Gen 3). They are going to be pricey though with a retail price of $1500. Our current setup with pushrods is $900.
