I'm the creator and owner of the diesel_shims shim kit. With over 3,000 kits sold and 25 sets personally installed, I bring years of experience working with Power Stroke engines. Nowadays you'll find cheaper Chinese knockoffs of my design that use inferior components, photocopies of my instruction sheets, and incorrect tools needed for the job. The headache you will encounter with these knockoff kits will not out-weigh the menial price difference!

Why Trust Me? I’m a 78-year-old mechanic with over 50 years of experience, and I’ve been working on 7.3 Power Strokes for over 25 years. I’m committed to helping DIYers keep their trucks running strong by sharing the knowledge I’ve gained through decades of hands-on experience.

Is Your Truck Having Trouble Starting or Missing? If your truck runs fine when warm but struggles to start or misfires, a full injector rebuild may not be necessary. Often, installing this shim kit is the solution. You might be experiencing low armature-to-adapter housing clearance, causing stiction. This is one of the most common causes for injectors to stop working.

How This Shim Kit Helps:

• Restores your injectors’ armature clearance to the original .004" to .005" specification, improving cold starts and boosting engine power.
• Extends injector life by up to 200,000 miles.
• No need to remove injectors for installation.

Kit Compatibility: This kit works with most HEUI injectors, including those in:

• 1994–2003 Ford 7.3L PowerStroke
• International T444E / DT466E / 1530E
• Cat 3126B top solenoid
• International Perkins 4.5L, 6.0L & 1300EDI HEUI injectors

Important Note: This kit does not fix injectors with faulty solenoids or other mechanical issues. If you need special tools for installation, check out my other listing (eBay Item #201596495902).
