Product Description
- 1.Applicable Models: Fits D-MAX Pickup, MU-X SUV, N-Series (NHR/NKR), F-Series Trucks, Trooper; compatible with 4JB1/4HK1/6HK1/4JJ1 engines (2000-present, Asia/Europe/Southeast Asia versions).
- 2.Material: High-strength ductile iron (C 3.4-3.8%, Si 2.2-2.8%, Mg 0.03-0.08%), ferrite-pearlite structure (60-75% pearlite). Tensile strength ≥600MPa, with excellent high-temp creep resistance for heavy-load operations.
- 3.Precision: IT6-IT7 grade; cylinder head flatness ≤0.04mm, Ra 0.4-1.2μm. Key holes (valve/fuel injector) have coaxiality ≤0.03mm, hole pitch tolerance ±0.015mm—ensures leak-free assembly.
Product Advantages
Solves high-temp cracking/deformation: 30% longer life than gray cast iron, less overhauls.OE-standard compatibility: direct replacement, no secondary processing—saves time/cost.Fits regional models (e.g., SEA D-MAX emission variants) to avoid mismatch.
