• 2011-2014 Ford F-150 (5.0L Coyote V8, All Transmissions)

Fitment Notes

• Fits ALL Ford 5.0L Gen 1 Coyote engine applications from 2011-2014 - covers standard nose radius crankshafts only
• NOT compatible with Large Radius (LR) crankshaft variants such as Winberg, Callies, or other aftermarket cranks with oversized nose radius - use standard CM-SP-11 for LR applications
• The GRIP surface version is NOT available in the Large Radius (LR) variant
• For 2015 and later Ford 5.0L Coyote engines, use part# CM-SP-15-GRIP
• Sold individually - 1 crankshaft sprocket per unit

Features

• GRIP surface - a knurled, high-friction front face that limits forward and rotational movement of the harmonic balancer on the crankshaft snout, improving crankshaft snout and keyway durability
• US-sourced Chromoly Steel billet construction - 10x stronger than OEM factory powdered metal sprockets
• Hot quenched with low temper heat treatment for maximum hardness combined with maintained toughness - no brittleness
• 80% more keyway cross-section than OEM, dramatically reducing the risk of keyway failure in high-horsepower, forced-induction, and high-RPM applications
• 30% heavier than OEM at 170 grams vs. 130 grams OEM - increased mass for added strength and stability
• Precision CNC machined and broached in-house at Boundary's USA facility for a snug, accurate crankshaft fit
• Dimensions verified after machining AND after heat treatment to guarantee fit consistency
• High-polish finish reduces friction and timing chain vibration for smoother, quieter operation
• Improved tooth geometry strengthens both the teeth and the keyway under load
• Made 100% in the USA with US-sourced materials
• Backed by Boundary's Limited Lifetime Warranty

Product Description

The Boundary CM-SP-11-GRIP is the definitive crankshaft timing sprocket upgrade for all 2011-2014 Ford 5.0L Gen 1 Coyote engines, covering the Mustang GT, Boss 302, Bullitt, and F-150 5.0L. The factory crankshaft sprocket is manufactured from powdered metal - an economical production material that is inherently porous and brittle under high-stress conditions. In stock naturally aspirated applications this is generally adequate, but the moment forced induction, high-RPM operation, or sustained track use enters the picture, the factory sprocket becomes the weakest link in the valvetrain. Boundary's response is a sprocket machined from US-sourced Chromoly billet steel, heat treated to maximum hardness, and proven to be 10 times stronger than the OEM piece with 80% more keyway cross-section - the most vulnerable failure point on the crankshaft nose.

What sets the CM-SP-11-GRIP apart from the standard CM-SP-11 is the addition of Boundary's GRIP surface - a precision-knurled, high-friction face on the front of the sprocket that bears against the harmonic balancer. This GRIP texture actively limits forward migration and rotational slippage of the harmonic balancer on the crankshaft snout, a known failure mode on high-power Coyote builds where balancer movement can gradually damage the snout and destroy the keyway. The GRIP surface works as a passive anti-slip interface, adding an additional layer of protection without requiring additional hardware. The sprocket is manufactured entirely in-house at Boundary's USA facility: CNC machined, broached, and dimensionally verified both after machining and after heat treatment to guarantee a snug, rattle-free fit on every unit.

At 170 grams - 30% more than the OEM 130-gram powdered metal sprocket - the CM-SP-11-GRIP also delivers improved tooth geometry that strengthens both the sprocket teeth and the keyway under load, and a high-polish finish that measurably reduces friction and timing chain vibration for smoother, quieter operation. This sprocket is recommended for all 2011-2014 5.0L Coyote builds using forced induction (supercharger, turbo, centrifugal blower), high-RPM naturally aspirated builds, and any application where long-term crankshaft reliability is a priority. Note: the GRIP version is not available in the Large Radius (LR) configuration for aftermarket crankshafts - LR applications should use the standard CM-SP-11. Backed by Boundary's Limited Lifetime Warranty and made entirely in the USA.
