Fork Seal Driver 31, 35, 39, 41 43, 46/47, 48, 49

otorcycle & Dirt Bike Fork Seal Driver Set – 35, 38, 39, 41, 43, 46–47, 48, 49mm

This is a complete fork seal driver set designed for motorcycle and dirt bike suspension rebuilds. The set includes 41mm, 43mm, 46–47mm, 48mm, and 49mm drivers, covering the most common front fork sizes used across KYB, WP, Showa, and many other OEM forks.

These drivers were designed, tested, and used during real suspension rebuilds. I’ve been running these drivers regularly in the shop and they get the job done without damaging seals or fork tubes.

Each driver is designed to provide even pressure around the seal for smooth, straight installation. The split-style design allows easy installation and removal while keeping the driver centered on the fork tube. These don't have the weight of a metal fork seal driver but they do work. Print 1 in a pinch or print the entire kit! Check out my other files for more suspension tools!

Printing Notes

• Recommended material: PETG
• PETG provides excellent strength, durability, and resistance to oils and chemicals commonly found during suspension service
• Print slow with good layer adhesion for best results
• I print with 7 walls to give them the most strength, weight and durability

I do sell this kit printed online, but I wanted to upload the files to help out fellow moto friends who have a 3D printer and like to wrench on their own bikes. I’ve drawn and tested a wide range of suspension tools and will continue uploading more as time allows.
