Dura-Bond High Performance Cam Bearings CH-25

Dura-bond CH-25 Camshaft Bearing Set for 2007-2013 LS Engines

Dura-Bond bimetal bearings are constructed of seamless steel tube with a thin layer of lead based babbitt material. Seamless construction makes installation easy, eliminating breakage and bearing surface interruptions. Lead based babbitt provides ideal properties for nearly all engine applications.  Babbitt's superior embeddability, conformability, and anti-seizure characteristics have proven to reduce engine failures that harder bearing materials can cause. The seamless, 100% machined surface design provides the tightest tolerances in the industry.  The centerless ground OD, centerless bored ID results in wall variations of .0004 in., giving the customer increased system design flexibility.

For 2003 and up engines, 2nd Design Positions 1 And 5 Housing Bore are 2.3460"/2.3480" 

LS2, L76, L77, LY6, L96, LFA, LZ1, LY5, LMG, LMF, LH6 LC9, LS3, L99, LSA, LS9, L92, L9H, L94, LS7, LY2, L20 

If you have a 1997-2003 1st Design Position 1 see listing CH-10

CH-25 can also be used in applications that call for the CH-23 cam Bearings (2004-2006 LS engines)
