I'm posting this in here in case some of you guys don't get into the GP section. We are running a GP for the SLP 1.8 rocker arm packages. As the aftermarket's foremost authority on late-model GM performance vehicles, SLP Performance Parts was among the first companies to develop power-enhancing hardware for the 3.8-liter F-Body. Now SLP is taking W-Body bolt-ons to the next level, with the introduction of our exclusive 1.8-ratio roller rockers for 3800-Series V6 engines.

As the workhorse of GM's passenger-car powertrain lineup, the 3800 is equipped with a mild camshaft suitable for use in a variety of vehicle applications. Simply increasing the rocker-arm ratio from 1.6 to 1.8 yields valve-lift figures of .464/.459" (stock is .413/.408")-enough to boost output by 10 plus hp, with no adverse effect on drivability.

Don't be fooled by the unrealistic horsepower claims made by other rocker-arm vendors. Our figures were obtained through rigorous testing of street-driven W-Bodies and have proved replicable on SLP's in-house SuperFlow chassis dyno.

These rocker arms are manufactured from high-strength T6 aluminum and feature a roller trunnion and tip that significantly reduce valvetrain friction over the stock steel units. Best of all, no valve-cover modifications or spacers are required for installation.

Note: Fits any 1997-2003 F/W-Body equipped with a supercharged or naturally aspirated 3800 V6. Package includes rocker arms, pushrods, detailed installation instructions, and all necessary hardware.
