Boundary Engineering Billet Oil Pump Gears and Crankshaft Sprocket Combo

Boundary Engineering 2015-2026 Mustang 5.0L / 5.2L GT350 Billet Oil Pump Gears and Crankshaft Sprocket Combo

Boundary oil pump gears are 100% manufactured in our Dallas, Texas production facility. We start by quenching our chromoly billets from extreme heat and then temper it to a tough indestructible core. After machining, we apply our ColdFlow surface hardening process and complete it to a Mirror Finish. What does all this give you? It gives you a pump with stability over 9000 RPM, proven over 2000whp, with higher efficiency, less friction, and backed by one of the industry’s best warranties.

Oil Pump Gear Features

• Mirror Finished and Surface Hardened
• Surface Ground gears for the ultimate in fitment and performance
• Indestructible chromoly core
• Inner and outer gear machined in matched sets
• Our own race-inspired gerotor design for flow and strength
• Each set hand, machine, and hardness inspected with Blueprinting Report

Billet Crank Sprockets from Boundary follows the same heritage as our oil pump gears, manufactured 100% in-house with US-sourced materials. These sprockets start with a chromoly steel that is ten times stronger than the OEM powdered metal, hot quenched with a low temper for the highest strength and resistance to wear.

• All sprockets heat treated to maximum hardness while maintaining toughness
• Precision CNC machined and broached for snug accurate fit
• Dimensions checked after machining and after heat treatment for guaranteed fit.
• 80% more cross-section versus OEM at the keyway
• Weighs 30% more than OEM at 170 grams vs 130 grams giving it the highest-strength sprocket on the market.
• High finish reduces friction and chain vibration
• New tooth geometry strengthens teeth and keyway
