Replacement main bearing set for the M30 and S38 engine.
COATING OPTION: These bearings are coated to dramatically increase their durability and useful life. If you’re building a race, or turbo motor these are the smart move.
IMPORTANT: It is extremely critical measure your crank prior (60mm std.) to ordering, on rare occasions cranks came with variations from the factory.
Note: There may be a slight additional cost for undersize bearings due to occasional factory supply constraints – we will notify you for authorization prior to billing in the event of price change. Oversizes subject to availability.
Fits all M30 and S38B35.
