Leaf Spring Slider Seat

Part No. 87029110091  ·  Cast-Steel Reinforced  ·  OEM-Spec Replacement

1. Product Overview

The Leaf Spring Slider Seat (P/N 87029110091) is a mission-critical chassis component engineered for Tongli (TONLY) wide-body mining dump trucks. Machined from high-strength cast steel and finished with anti-corrosion coating, it serves as the load-bearing interface between the leaf spring pack and the axle housing — absorbing continuous shock, torsion and vibration under the most punishing off-road mining conditions.

Designed to OEM specifications, this slider seat guarantees a 100% bolt-on fit with zero on-site machining. Whether you operate a single TL875B or manage an entire fleet of TLE-series electric mining trucks, part 87029110091 delivers the durability, alignment precision and service life your operation demands.
