Seamless construction makes installation easy, eliminating breakage and bearing surface interruptions. Just wondered if anyone else has run into this and what you have used?Īlso found this on the standard Dura-Bond series: Product Description Dura-bond CH-23 Camshaft Bearing Set for 2003-2009 LS Engines Dura-Bond bimetal bearings are constructed of seamless steel tube with a thin layer of lead based babbitt material. Guess I'll measure all the bearings and cam bearing journals to be positive. Started looking at the Dura-Bond with PTFE coating but they show one set for '97-'03 and one set for '03-'09.
I was going to buy OEM GM bearings but all the GM outlets only show the iron block bearings for my model. I want to replace the cam bearings and thought it would be easy like most engines but have found different information in various places.
Started tearing apart my '11 LC9 Aluminum block 5.3l so I can order parts.
