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 and centerless bored ID results in wall variations of under .0004".

Fits: 2007 and up blocks, where bearing position 1 and 5 housing bores measure 2.3460" to 2.3480"
CH-25 can also be used in applications that call for the CH-23 cam Bearings (certain 2003-2006 LS engines)
Dura-bond's CHP-25 is a high performance, higher load-capacity version of their CH-25 bearing
