LOSB4104 Outer Pivot Pin Set (4): LST2/XXL/2, LST 3XL-E

Losi LOSB4104 Outer Pivot Pin Set (4): LST2 / XXL / 2, LST 3XL-E

The LOSB4104 Outer Pivot Pin Set is a genuine Losi suspension hardware component designed for large-scale platforms including the LST2, LST3XL-E, and XXL series vehicles. These pivot pins are used to secure the outer ends of the suspension arms, allowing controlled movement while maintaining proper alignment within the suspension system.

The pivot pins play an important role in ensuring smooth suspension articulation and consistent geometry under load. Built from durable metal, they are designed to withstand the high stresses of large-scale monster truck driving, including hard landings, impacts, and heavy off-road terrain use.

Over time, pivot pins can wear, bend, or develop slop in the suspension system, which may lead to loose handling, reduced precision, or uneven suspension movement. Replacing worn pivot pins helps restore tight, accurate suspension performance and reliable handling.
