LIVERNOIS MOTORSPORTS GM LS ROCKER ARM BASE FOR STOCK HARDWARE

$159.99

SKU LPP821101 · Camshafts & Valvetrain

Description

Livernois Motorsports Billet LS rocker arms stands are available to help improve valvetrain and rocker arm control. With added spring pressures and larger camshafts the load imposed on the factory OE rocker stand and bolts often allows for flex and distortion. This translates into lost valve motion as the rocker arm deflects on the stand. These stands offer increased rigidity to keep rocker motion more true.  These bars are for OEM casting Cathedral port LS series engines only, such as LS1, LS2, LS6, etc .

**These are for Stock Bolts and Hardware.  For upgrading to ARP Bolts, use Rocker Base: LPP821102 (ARP bolts included)
