BMW B58 Sleeving Service

We offer the machining service on your BMW B58 block to install our custom designed LA Flanged Sleeves into your B58 block. This is a great solution for overboring an engine or repairing an block with too much damage. The stock B58 block has a steel liner that is very thin (about .010") so any minor damage can take it beyond repair with a simple bore and hone. Our sleeves are built to handle boost and do not compromise the strength of the block. They can be used with the stock B58 pistons or with some of the custom CP pistons we offer for sale.
