Dorman Engine Timing Camshaft Gear

Dorman Engine Timing Camshaft Gears: Engineered to Outlast the Original

When a variable valve timing (VVT) system starts rattling, hesitating, or throwing codes, the culprit is often a worn or failed camshaft gear — also known as a cam phaser or timing sprocket. The variable valve timing sprocket is key to ensuring an engine's performance and clean running. Original equipment camshaft phasers often fail due to excessive internal wear, leaving drivers with rough idle, loss of power, and costly repair bills. This is precisely the kind of problem that Dorman was built to solve.

The Dorman OE FIX Approach to Cam Phasers

Since 1918, Dorman has been the automotive aftermarket's pioneering problem solvers, releasing thousands of parts that people could once only buy from original equipment manufacturers. Their hallmark OE FIX philosophy is at the heart of their engine timing camshaft gear lineup. In the course of gathering and analyzing new ideas, Dorman often finds a critical flaw in the original equipment that causes a part to fail prematurely — or finds that people want to repair a vehicle in a fast, cost-effective way, but the original manufacturer doesn't sell the specific parts they need. Whenever they develop a solution to these problems, they call it an OE FIX — simply a repair solution you can't get from the OEM.

In the camshaft gear category, that commitment to improvement is tangible. Dorman's OE FIX camshaft gear features a stronger alloy plate and improved rotor design to reduce friction and increase reliability. For specific applications — such as certain Ford and Lincoln trucks and SUVs equipped with the 3.5L V6 EcoBoost engine — Dorman's engineering goes even further.

Key Upgrades Over OEM Design

Dorman's cam phaser improvements address the root causes of OEM failure rather than simply duplicating the factory part. Notable design enhancements include:

• Two-Step Locking Pin: A two-step locking pin with a thicker seat top, longer seat stem, and deeper receiving pin seat replaces the factory sprocket's straight pin design, providing more secure engagement and stability during phaser actuations, eliminating the rattling typical of a malfunctioning sprocket.
• Advanced Oil Wiper Design: Dorman cam phasers feature innovative oil wipers designed with twin sealing edges, an upgrade from the factory's flat wiper profile. This seals oil more effectively for faster advance and retard actuations and reduced wiper wear.
• 100% New Construction: Each variable valve timing sprocket is entirely new, not a remanufactured part, and is precision machined from durable steel for reliable, long-term performance.
• Validation Tested: Dorman's cam phaser tester ensures reliability by simulating 50,000 miles of real-world driving in four weeks, and a special service tool is included for hassle-free installation.

Vehicle-Specific Fitment You Can Count On

Each vehicle-specific application has been validation tested to ensure quality and a direct fit. Whether you are a professional technician or a dedicated DIYer, Dorman's camshaft gears are designed to install and perform like the original — or better. Dorman's reputation is supported by catalog breadth, fitment confidence, and OE FIX-style problem-solving, making them a dependable choice for precision engine timing repairs.
