Boundary COMBO-GRIP-11-HBB Billet Crankshaft Timing Sprocket with Grip Surface and Harmonic Balancer Stud Kit

The Boundary COMBO-GRIP-11-HBB is a high-performance combination kit designed to strengthen and protect the crankshaft snout on Ford Coyote 5.0L engines. This kit addresses a common failure point in performance applications by reinforcing the crankshaft keyway and limiting harmonic balancer movement, preventing keyway cracks and ensuring precise balancer alignment.

Premium Construction and Materials:

• CNC-machined from chromoly steel that is ten times stronger than OEM powdered metal
• Heat-treated to maximum hardness (Rockwell C 50-55) while maintaining toughness
• Precision broached for a snug, accurate fit with dimensions verified after machining and heat treatment
• Weighs 30% more than OEM at 170 grams versus 130 grams for superior strength
• Features 80% more cross-section than stock at the keyway for enhanced durability
• Special grip surface texture limits harmonic balancer movement and keyway wear

Performance Benefits:

• Significantly reduces vibrational forces for improved engine smoothness and longevity
• New tooth geometry strengthens timing chain engagement and reduces friction
• High-quality finish minimizes chain vibration and wear
• Manufactured 100% in-house by Boundary using US-sourced materials
