Moroso 61757 Crankshaft Socket Tool for Degree Wheel GM LS Series

The Moroso 61757 Crankshaft Socket Tool is purpose-built for engine builders who need a reliable, damage-free method of rotating the crankshaft during cam degreeing procedures. By slipping this socket over the crankshaft snout — rather than using the crank hub retaining bolt — builders gain a secure, positive-engagement solution that protects critical engine hardware.

Key Features:

• 1/2 in. drive — Works with any standard 1/2 in. drive ratchet or breaker bar for easy engine rotation
• Broached keyway — Slides over the crankshaft snout and key for positive, slip-free engagement
• Knurled jam nut — Allows precise degree wheel positioning; can be loosened and rotated independently of the socket body
• Simplifies TDC/BDC location — Makes it straightforward to find Top Dead Center and Bottom Dead Center when degreeing-in camshafts
• Compatible degree wheels — Designed for use with Moroso Degree Wheel No. 62190 (11 in.), No. 62191 (18 in.), and No. 62192 Dual (18 in.)
• GM LS Series fitment — Engineered specifically for GM LS engines equipped with a crankshaft keyway

Proper cam degreeing is essential for maximizing engine performance, and the Moroso 61757 makes the job cleaner and more precise. Remove the crank hub or balancer, install this socket over the snout, and use it with your preferred Moroso degree wheel for accurate, repeatable results on every build.
