Stop The Damage Before It Starts With This Smart Upgrade

If you're building or maintaining a 1999–2003 Ford 7.3L Powerstroke, upgrading your 4R100 transmission with the SunCoast Coast Clutch Frictions PTO Kit is a move you won’t regret. This isn’t just about adding parts, it’s about fixing a known weak point before it turns into a major headache. The upgraded coast clutch drum in this kit doubles the number of friction elements compared to stock, which means better holding power and less heat during operation. It also corrects a common issue where the retaining ring can become dislodged, leading to serious internal transmission damage. Whether you're towing heavy or just want peace of mind behind the wheel, this kit is built to take the abuse. You get four brand-new frictions, four steels, a CNC-machined pressure plate, and a reinforced snap ring, all designed to hold up under stress and deliver smooth, reliable engagement.

Designed To Eliminate Weak Points In The 4R100 Coast Drum

The SunCoast 4R100CC4PTO Coast Clutch Frictions PTO Kit provides a technical solution to one of the most common failure points in the 4R100 transmission used in 1999–2003 Ford F250 and F350 trucks with the 7.3L Powerstroke. This upgraded drum increases durability by doubling the number of friction surfaces in the coast clutch, improving overall torque-handling capability and reducing heat generation during coastdown events. One of the most critical improvements is the prevention of retaining ring dislodgement, a frequent issue in the factory setup that can cause extensive damage to the transmission internals. The kit includes four friction plates, four steels, a precisely CNC-machined pressure plate, and an upgraded snap ring that ensures consistent and secure retention. These components work together to increase clutch surface area and holding strength without sacrificing fitment or factory clearances. Designed for high-performance use, heavy-duty towing, or just improved reliability, this kit is a well-engineered enhancement for any 4R100 rebuild. It’s a direct-fit performance solution from SunCoast, a name trusted by diesel builders and transmission specialists alike.
