Overview
Why Use the Enduro Max 6903 in Your Suspension Pivot?
The Enduro Max 6903 is engineered specifically for suspension pivots, deploying a full-complement ball design that maximizes the number of balls in the race for significantly higher load capacity than standard cartridge bearings of the same size. The race grooves are cut deeper than standard, providing greater lateral support against the twisting and compound forces that suspension pivots experience with every bump, berm, and bottom-out. LLU seals face outward toward the elements, keeping mud, water, and trail grit away from the bearing interior.
The 17mm x 30mm x 7mm profile makes the Max 6903 a common fit for rear triangle pivots across a range of trail and all-mountain frames. Almagard Extra High Pressure Grease fills 90% of the bearing cavity, providing robust lubrication under the heavy, sustained loads that active suspension generates ride after ride. Whether you are rebuilding a pivot on a new frame or swapping out worn bearings on a proven build, the Max 6903 is the right bearing for the job.

FAQ
Good questions
Get to know Enduro
There's more to Enduro than this one product. Our Enduro page has the full Enduro lineup we carry and more about the brand.
Visit the Enduro page →What makes the Max 6903 better than a standard 6903 for pivots?
The full-complement design packs more balls into the bearing without a cage, delivering up to 45% greater load capacity and deeper race grooves for improved lateral stability under the complex forces suspension pivots generate.
Is the Max 6903 compatible with my frame?
The 6903 dimensions (17x30x7mm) fit many rear suspension pivot applications across trail, all-mountain, and enduro frames. Always verify your frame spec or measure the existing bearing before ordering.
How do LLU seals differ from standard bearing seals?
LLU seals use a double-contact design for maximum protection against water, dirt, and mud ingress. They provide a stronger seal than single-contact or non-contact options, making them ideal for exposed suspension pivot applications.
