• Material Specifications

We offer four main material types for the No.2 Gear Shift Fork, each tailored to specific application scenarios with unique core advantages.

The first is Low-Carbon Alloy Steel, available in grades SAE 8620 (20CrMnTi) and SAE 4120, which is ideal for carburizing treatment and suitable for high-demand passenger cars and heavy-load scenarios; it achieves a tough core and ultra-hard surface, resisting high impact and wear during frequent gear changes.

Next is Medium-Carbon Structural Steel, with grades SAE 1045 (45#) and SAE 4140, suitable for induction hardening and used in light-duty vehicles, commercial vans, and urban logistics cars; it is cost-effective with stable performance, balancing durability and economic efficiency for daily-use vehicles.

High-Strength Aluminum Alloy, in grades 7075-T6 and 6061-T6, is reserved for racing cars and ultra-lightweight modified vehicles; its ultra-lightweight design reduces transmission load, though it requires hard anodizing or coatings to enhance wear and corrosion resistance.

Finally, Powder Metallurgy (PM), specifically iron-based PM, is ideal for high-volume passenger car applications and compact transmissions; it is suitable for complex shape production with low cost and can be oil-impregnated for self-lubrication, reducing maintenance frequency.

• Heat Treatment & Surface Finish

Carburizing & Hardening (Applicable to Low-Carbon Alloy Steel Forks)

Surface Hardness: 58 – 64 HRC (for contact surfaces and fork fingers) – ensures extreme wear resistance under high friction.

Core Hardness: 30 – 45 HRC – maintains impact toughness to prevent cracking during heavy-load gear changes.

Effective Case Depth (ECD): 0.6 mm – 1.2 mm (adjustable based on gear module and load capacity) – optimizes durability and service life for different vehicle models.

Induction Hardening (Applicable to Medium-Carbon Steel Forks)

Hardness: 50 – 58 HRC (limited to key contact areas) – focuses wear resistance on high-stress regions.

Characteristics: Minimal thermal distortion, high processing efficiency, and shallow case depth – suitable for mass production of light-duty vehicle parts.

Surface Treatments

Phosphating: Provides black or gray phosphate coating. Improves initial running-in performance, accelerates adaptation to working conditions, and enhances rust/corrosion resistance in harsh environments.

• Additional Notes

Compatibility Confirmation: This No.2 Gear Shift Fork is designed for Japanese and Korean vehicle models. Please verify your vehicle model, original part number, and transmission type before ordering to ensure a perfect fit.

Installation Guidance: Professional installation by certified technicians is recommended. Incorrect installation (e.g., misaligned shift rails, improper torque) may cause shifting jams or premature wear.

Storage Requirements: Store in a dry, ventilated environment to avoid rust or corrosion. Keep away from moisture and corrosive substances to maintain material performance.

Lubrication Maintenance: Regularly lubricate the transmission system with OE-specified lubricants during use to extend the service life of the gear shift fork and related components.

• Precision Manufacturing & Quality Control: Adopts advanced CNC machining and precision testing equipment to ensure dimensional accuracy within 0.01mm tolerance. Each fork undergoes strict hardness, wear resistance, and fatigue testing to meet or exceed OE standards, guaranteeing stable performance in long-term use.

• Material Innovation for Diverse Needs: Offers a full range of material options (alloy steel, carbon steel, aluminum alloy, PM) to match different vehicle types and usage scenarios. Customizable material and treatment solutions meet the demands of daily commuter vehicles, heavy-load commercial vehicles, and high-performance racing cars.

• Expertise in Japanese & Korean Models: Years of focus on Japanese and Korean vehicle transmission systems, with a dedicated database of part models and parameters. Ensures 100% compatibility with mainstream brands like Toyota, Hyundai, and Mitsubishi, avoiding the risk of mismatched parts.

• Cost-Effective B2B Solutions: Small-batch order support reduces inventory pressure for distributors; cost-effective material options (e.g., medium-carbon steel) lower procurement costs without sacrificing quality. Customizable packaging also helps build brand competitiveness in the aftermarket.

• Reliable After-Sales Service: 12-month warranty and professional technical support team provide timely solutions to product usage, installation, and compatibility issues. Long-term supply of spare parts ensures continuous support for business partners.

Choose our No.2 Gear Shift Fork for precise fit, durable performance, and comprehensive B2B support—your ideal partner for auto parts procurement in the Japanese and Korean vehicle aftermarket.
