Factory Links OEM Series® Lower Shock Bearing Kits provide a complete solution for rebuilding the lower shock mounting assembly—restoring smooth suspension movement, eliminating play, and ensuring proper load transfer between the shock and linkage.

Designed to meet or exceed OEM specifications, these kits deliver OEM-level performance and durability at a significantly lower cost than purchasing individual components through the dealer. Each kit includes precision-manufactured needle bearings, pins, collars, and Nitrile Butadiene Rubber (NBR) dust seals engineered for proper fitment and long service life.

The lower shock mount is subjected to high-impact loads, constant articulation, and direct exposure to water, mud, and debris, making it one of the most demanding wear points in the suspension system. Factory Links components are specifically designed to handle these conditions while maintaining smooth operation and structural integrity.

Each kit contains all components required for a complete lower shock rebuild, helping extend service intervals and restore suspension performance in motocross, enduro, and off-road riding conditions.

Not all bearing kits are created equal. Factory Links components are engineered specifically for off-road suspension systems—not adapted from general industrial applications.

Technical Details

HEAVY-DUTY NEEDLE BEARINGS

Factory Links lower shock needle bearings are designed specifically for high-load suspension pivot applications, where constant articulation and impact forces demand greater durability than standard bearing solutions.

  • Full-complement needle bearing design for increased load capacity
  • Precision-manufactured bearing surfaces for smooth suspension movement
  • Optimized internal clearances for consistent performance under load
  • Engineered to withstand shock loads, vibration, and repeated impact

These bearings are built to maintain smooth operation under the extreme conditions found in motocross, enduro, and off-road riding.

PRECISION PINS

Factory Links pins are manufactured from high-grade bearing steel and engineered to provide a durable, low-friction interface within the shock mounting assembly.

  • Precision-machined for accurate fitment and alignment
  • Induction hardened for increased surface durability
  • Polished contact surfaces to reduce friction and wear
  • Designed to handle repeated load cycles and high-stress conditions

Proper pin hardness and finish are critical to preventing premature wear in suspension pivot systems.

HARDENED COLLARS

Factory Links collars are designed to maintain proper spacing and load distribution within the shock assembly.

  • Precision-turned for exact dimensional accuracy
  • Hardened for improved wear resistance
  • Zinc-plated for corrosion protection
  • Manufactured to maintain alignment under load

These components play a key role in ensuring consistent suspension performance and preventing misalignment.

OFF-ROAD SPECIFIC DUST SEALS

Each kit includes premium Nitrile Butadiene Rubber (NBR) dust seals designed to:

  • Prevent intrusion of water, mud, sand, and debris
  • Protect internal components from contamination
  • Retain lubrication within the bearing assembly
  • Maintain sealing performance in aggressive riding conditions

These seals are purpose-built for off-road environments—not general industrial use.

FAQs

Q: What is included in a Lower Shock Bearing Kit?
A: Each kit includes all components required to rebuild the lower shock mount, typically including needle bearings, pins, collars, and dust seals specific to your motorcycle model.

Q: Why is the lower shock bearing important?
A: The lower shock mount is a critical pivot point in the suspension system. Worn bearings or pins can cause play, poor suspension performance, and uneven load distribution, which can affect handling and component longevity.

Q: How do I know if my lower shock bearings need replacement?
A: Common signs include excessive play in the rear suspension, knocking or clunking under load, rough or restricted movement, or visible corrosion and contamination during inspection.

Q: How are Factory Links kits different from generic aftermarket kits?
A: Many aftermarket kits use standard components not specifically designed for off-road suspension loads. Factory Links kits are engineered with high-grade materials, optimized tolerances, and sealing systems designed to resist contamination and handle high-impact riding conditions.

Q: Is this kit suitable for motocross, enduro, and off-road use?
A: Yes. Factory Links lower shock kits are specifically designed for off-road riding conditions, where durability, contamination resistance, and consistent suspension performance are critical.

Q: Do I need special tools for installation?
A: Installation typically requires a bearing driver or press tools to properly seat components without damage. Care should be taken to install bearings squarely and ensure proper alignment of pins and collars during assembly.
