Application and fitment
Applicable BBT GM LS / engine-family routes shown for this product. Confirm the exact engine code and build before ordering. Supplier part number: 871223KS
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.
