Designed specifically for our ZL402 LS1 Gen III and LS2 Gen IV stroker engines using the SLP/L92 cylinder heads, this camshaft will make the most torque for these applications. With the proper tuning, this camshaft will idle down to 800 RPM and packaged with our ZL402, it's ideal for your Silverado/Sierra for unbeatable towing power. 

NOTES: Custom PCM reprogramming required, not included. SLP recommends final installation and tuning be performed by an experienced, professional mechanic. 

This camshaft has a 3 bolt core and will only work on a 3 bolt cam sprocket. 2007 and later LS2 engines have a single bolt core cam and cannot use this camshaft.
