2006 Chevy Silverado - Slick SIlverado

Prior to installation, the new rockers were soaked briefly in a cup of motor oil.

With the SLP rockers installed on the factory tray, the assembly was simply slipped back onto the cylinder head and torqued down.

The underhood mods were finished with SLP's cold-air kit, which simply replaces the factory air box. After installing the SLP box and cone filter, a lid sealed it all up.

The cold-air kit also included a new intake tube from the box to the throttle body.

Here's a look under the hood with the SLP air box and headers in place. If we had included X-ray glasses with this issue, you'd see the new rockers through the valve covers, too.

Wrapping up the package was the downloading of SLP's custom tune, which is stored on an SLP-supplied DiabloSport II handheld tuner. The tuner enabled the engine and computer to work with the revised rocker arm ratio and increased airflow enabled by the cold-air kit, headers, and after-cat exhaust. It can be tuned to perform on regular or premium fuel; the premium blend, of course, delivering the highest performance.
