The Merchant Automotive Engine Seal Driver Kit includes both crankshaft main seal drivers and new front and rear main seals, so you can replace both main seals on a 2001 - 2026 Duramax in one job. Main seals have to go in perfectly square and at the correct depth, or they leak again quickly. These drivers set each seal exactly where it belongs every time.

Both drivers are CNC-machined from 6061 billet aluminum with a black anodized finish and are made in Holland, Michigan.
