1.Dynamic Phase Adjustment to Unlock 5.7L Engine Power
·It collaborates with the ECU to achieve ±16° phase adjustment via high-pressure hydraulic technology: Under high-load scenarios (off-roading, overtaking), it advances intake valve timing to increase charging efficiency by 12%-15% and peak torque by 8%-10%, solving low-speed lag in large-displacement engines; at medium-low speeds, it retards timing to optimize the air-fuel ratio, ensuring smooth daily driving.
2.Optimized Combustion to Address Large-Displacement Pain Points
·It improves combustion efficiency to over 91%, reducing fuel consumption by 5%-8% compared to faulty parts (the Grand Cherokee 5.7L saves approximately ¥1,800-2,500 in annual fuel costs). It minimizes residual hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxide (NOx) emissions, meeting China VI b and U.S. EPA Tier 3 standards and avoiding emission compliance issues.
3.Stable Transmission to Protect Engine and Mitigate High-Load Risks
·Its OE-designed involute tooth profile ensures precise meshing with the timing chain (clearance ≤0.04mm), preventing transmission slippage under high torque of large-displacement engines. It real-time corrects phase deviations to avoid valve-piston collisions in the 5.7L engine, reducing failure risks during off-roading/heavy loading and extending engine service life.
1.OE-Grade Custom Compatibility for High-Pressure Systems
·Specifically engineered for the Grand Cherokee 5.7L HEMI engine, it enables direct replacement without structural modifications, withstands 25MPa high oil pressure, and has a compatibility error ≤0.1mm—eliminating abnormal noise and adjustment failure caused by non-specialized parts.
2.Factory-Direct Cost-Effectiveness to Reduce Maintenance Costs
·It is 35%-50% cheaper than OE parts (saving ¥1,000-1,500 per replacement) and only 10%-15% more expensive than ordinary aftermarket parts, while matching OE performance. Its after-sales repair rate is <3% (far lower than the 25%+ rate of ordinary aftermarket parts), making it ideal for bulk stocking.
3.High-Strength Material for Harsh Conditions and Longer Life
·Made of SCM435 alloy steel with carburizing and quenching (hardness HRC 59-62), it withstands 200℃ high temperatures and 25MPa high pressure. Equipped with imported fluororubber seals to prevent leakage, it has a service life of 80,000-120,000 km (1.5-2 times that of ordinary aftermarket parts), suitable for high-load use of large-displacement engines.
