Durabond – Cam Bearings for LS engines 2003 and Older (CH-10)

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 embedability, 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.

These bearing are for 1997-2003 1st Design Position 1 and 5 housing bores are 2.3260″/2.3280″

For 2003 and up engines, 2nd Design Positions 1 And 5 Housing Bore are 2.3460″/2.3480″ see part CH23.
