Heatspin high-quality aluminum alloy piston set is tailor-made for Isuzu 4HJ1 four-cylinder diesel engines with 115mm bore diameter, featuring outstanding heat resistance and structural rigidity against long-term heavy-load vehicle operation.
Processed with micron-level CNC precision machining and matched OEM part number 8-97228-302-0, it maintains ideal fit clearance with cylinder liners to prevent gas blow-by and stabilize engine compression efficiency.
Optimized thickened ring groove design slows piston ring wear effectively, eliminating typical engine defects including oil burning, insufficient power output and black smoke exhaust caused by aging original pistons.
Premium smooth surface finishing reduces friction coefficient between piston and cylinder liner, cutting abnormal oil consumption and extending the overall service life of the diesel engine assembly.
All raw aluminum materials and finished piston kits undergo full dimensional, hardness and durability inspection to meet international automotive spare parts quality standards.
We provide a 100,000 km or 1-year after-sales warranty to lower maintenance risks for auto repair shops, freight fleets and global wholesale buyers.
Multiple export packaging modes are available, including branded Heatspin cartons, customized printed packages and shockproof neutral boxes for safe ocean bulk shipment worldwide.
Flexible order options cover bulk kit wholesale and single part supply, compatible with Isuzu Mitsubishi Toyota Hino Nissan Mazda Komatsu Hyundai Kia series engines to satisfy diversified global procurement demands.
