Crow Cams LS1 3-Bolt Standard Replacement Camshaft

LS1 3-Bolt Standard Replacement Camshaft is a factory-style replacement camshaft for its specified engine and cam-drive configuration. It is intended to retain the appropriate original valvetrain arrangement rather than automatically requiring performance hardware.

Product specifications

Application and fitment

Holden VT–VZ LS1, 1999 onward; confirm original camshaft attachment and engine configuration.

Supplied contents

One camshaft for the specified position/profile. Matching camshafts, lifters, springs, retainers and installation hardware are not included unless explicitly stated for this SKU.

Installation and configuration

• Confirm the camshaft part number, engine generation, camshaft drive, trigger arrangement and cylinder-head compatibility before installation.
• Degree the camshaft where required and measure piston-to-valve, valve-to-valve, spring coil-bind and retainer-to-seal clearances on the actual engine.
• Check lifter type, hydraulic preload or mechanical lash, rocker geometry, pushrod length where applicable and the required spring/retainer package.
• An active-AFM/DOD engine requires the correct mechanical conversion before a non-AFM camshaft is fitted; update the ECU calibration as required.
