Peterson Fluid 06-4113-L 3-Bolt Spline Drive Hub Ford ATI MSD Left-Hand Drag

The Peterson Fluid Systems 06-4113-L is a 3-bolt spline drive hub designed for Ford engines equipped with ATI or MSD balancers in left-hand drag racing drive configurations. Peterson's spline drive system offers a strong, reliable alternative to standard drive mandrels, providing positive, slip-free power transfer from the crankshaft to accessory drive components.

Unlike conventional setups, the spline drive design eliminates the need for the long crank bolt that can create reliability issues in high-performance and racing applications. The billet aluminum construction keeps weight to a minimum while maintaining the durability demanded by competition use.

Key Features:

• 3-Bolt mounting pattern for secure, positive attachment to the balancer
• Left-hand (drag racing) orientation — suited for drag race drive configurations
• Compatible with ATI and MSD balancers/crank triggers on Ford engines
• Eliminates the problematic long crank bolt found in traditional mandrel setups
• Lightweight aircraft-grade billet aluminum construction
• Works with Peterson's complete line of splined pulleys, spacers, and guide washers
• Designed for use with Gilmer, HTD, or V-belt accessory drive systems

Peterson Fluid Systems spline drive sets include the hub along with appropriate mounting hardware for installation to the balancer. This hub is part of Peterson's comprehensive spline drive lineup used across drag racing, pavement late models, and big block modified applications.
