Stellar Automotive Group 5R110W Direct Coast Piston fits Ford 03-Up

Stellar Automotive Group 5R110W Direct Coast Piston – Compatible for Ford Super Duty 2003-Up

Stop engine runaway on deceleration and burnt direct coast clutches with this precision molded direct coast piston from Stellar Automotive Group.

The factory direct coast piston commonly cracks or loses its lip seal under extreme diesel torque and heat, causing loss of coast apply pressure — resulting in no engine braking, high RPM overrun when letting off the gas, and rapid clutch failure. This direct-replacement molded piston features a permanently bonded rubber sealing lip that stays flexible and leak-free, restoring full coast-down function and smooth engine braking even under heavy towing.

Perfect fit for 2003-2010 models including:

• Ford F-250, F-350, F-450, F-550 Super Duty
• Ford Excursion
• All 6.0L & 6.4L Power Stroke with 5R110W

Symptoms of a failing direct coast piston:

• Engine revs freely when coasting in gear
• No engine braking (especially in lower gears)
• Ratcheting noise or slipping on overrun
• Burnt direct coast frictions on teardown

Don’t let a $50 piston destroy your direct coast pack — install the Stellar Automotive Group bonded direct coast piston and feel the engine braking return instantly.
