8-97011596-2 CYLINDER SET; CAR LOCK for ISUZU NPR58/4BE1

Engineered to Isuzu’s Exact Installation Specifications

The Spring Pin Assembly is a seemingly small but mission-critical component, used throughout Isuzu vehicles to secure shift forks, selector shafts, and other moving parts within the transmission, transfer case, and gear shift mechanisms. Isuzu Genuine Spring Pins are manufactured to exact OEM specifications for length, diameter, and material temper, ensuring a perfectly tensioned fit. This precision guarantees that components like the shift arm are locked securely in place, maintaining the precise geometry of the shift linkage for reliable gear changes.

Built to Withstand Constant Load and High-Frequency Vibration

Unlike standard solid pins, the spring pin’s unique slotted, tubular design provides a constant outward spring force, allowing it to maintain a tight interference fit within its bore, even under intense vibration. Isuzu Genuine Spring Pins are formed from high-grade spring steel and treated to resist fatigue, shearing, and corrosion. This robust construction prevents the pin from loosening or backing out over time, a common failure with generic pins that can lead to erratic shifting or mechanism disengagement.
