Wrist Pin Bearing

Restore smooth, reliable top-end operation with a high-quality HOT RODS wrist pin bearing. The WB108 is an OEM replacement bearing designed for the connecting rod small end, helping reduce friction and wear where the wrist pin (piston pin) rotates at very high speed. Its case-hardened bearing cage and performance-oriented cage profile are made to better handle high-RPM use, making it a smart choice for rebuilds and preventative maintenance.

When a wrist pin bearing wears, it can introduce noise, increased play, and accelerated damage to the piston and rod. Replacing it during a top-end service helps keep your engine running smoothly and protects critical components.

Key features:

• ✅ OEM replacement fit – designed as a direct replacement wrist pin bearing
• ✅ Case-hardened bearing cage – improved durability under load and heat
• ✅ High-RPM suited cage profiles – KU (flat) and KZ (long-shouldered) styles used for better high-rev performance (KZT style)

Benefits of use:

• 🔹 Helps extend engine life by reducing wear at the connecting-rod small end
