For wholesalers and agents, the 894251-0316 offers an OEM-standard solution with exceptional thermal stability. Its superior heat dissipation protects the cylinder head, helping you build trust with repair centers by providing parts that significantly extend engine overhaul intervals.
Product Features
Hardened Heat-Resistant Alloy Constructed from premium chromium-alloy steel to prevent surface deformation and impact wear under the intense cycles of the 4LB1 engine.
Superior Thermal Conductivity The 894251-0316 allows rapid heat transfer from the valve to the cylinder head, preventing valve stem warping and extending the life of the valvetrain.
Precision CNC Machining Features micron-level dimensional accuracy to ensure a 100% airtight seal with the valve face, immediately restoring original engine compression.
Stable Interference Fit Machined to strict tolerances to ensure the seat remains securely positioned in the cylinder head during extreme thermal expansion and contraction.
Direct OEM Compatibility Produced as a 1:1 replacement for Isuzu 4LB1 engines, guaranteeing a seamless fit and long-term mechanical reliability in TCM and industrial equipment.
