Installation Notes and Tips

Verify engine family, displacement, and bearing housing bore before installation. This set is listed for standard size only, so confirm the block has not been machined for oversize bearings. Fitment notes call out 1st Design applications with position 1 and 5 housing bore dimensions of 2.3260 in to 2.3280 in, so matching the block specification is important before assembly.

For best results, clean and inspect the cam tunnel, measure all bearing bores, and follow the engine builder’s installation procedure for LS1 cam bearing alignment and lubrication.

Quality Assurance

Sealed Power states that its parts use modern materials and ISO- and QS-certified manufacturing processes to meet the demands of current engine applications. That manufacturing approach supports consistent fit and finish for rebuilders working with Chevrolet Gen III V8 engines.

Part number 1888M is a focused OE replacement choice for LS1 camshaft bearing service in Chevrolet and GMC applications.
