Starter Bolt, Duramax | 2001 - 2022

Starter Bolt, M12 x 40, Duramax | 2001-2022

This is the genuine GM starter mounting bolt, GM part number 97329632, for the 2001-2022 6.6L Duramax trucks and the 2006-2016 Duramax vans. It is the factory M12 x 40 flanged bolt that holds the starter to the engine. Starter bolts can loosen or break from engine vibration, and a loose starter can lead to grinding, poor engagement or damage to the starter and flywheel teeth.

Key Features

• Genuine GM part number 97329632 (GM name: M12x40 Starter Bolt)
• M12 x 40 mm metric thread, 31.85 mm (1.25") thread length
• Steel hex-flange head, 15 mm wrench size
• Sold individually
• 1-year warranty

Benefits

The Duramax starter is heavy, and engine vibration works on its mounting bolts over time. Replace any bolt that is broken, stretched or has damaged threads, and use new OE bolts when the starter is replaced so it seats tight and stays aligned with the flywheel.

Fitment

Fits 2001-2022 Chevrolet Silverado and GMC Sierra 2500HD and 3500 with the 6.6L Duramax (LB7, LLY, LBZ, LMM, LML, L5P), and 2006-2016 Chevrolet Express and GMC Savana 2500 and 3500 vans with the 6.6L Duramax.
