16pcs Lifter & 16pcs Rocker Arm 53020742AB 53020742AC+53021077 Compatible For Jeep Grand Cherokee WJ 4.7L 1999-2004 EEP/WJ/099A
- High end material: Made of selected alloy steel, with QPQ composite surface treatment and overall quenching and tempering heat treatment, the hardness of the head circular arc surface reaches 54-60HRC, which can withstand high load and high-frequency operation of the engine, greatly reducing the risk of wear and deformation.
- Optimizing engine valve efficiency: using a roller type contact structure combined with DLC low friction coating, the friction coefficient is reduced to 0.08, reducing the friction loss between the valve and rocker arm.
- Installation adaptation with zero error: Strictly follow OE factory specifications and IT6 level tolerance standards for processing, with a roughness Ra ≤ 0.4 μ m for key parts, and a precise control of the fit clearance between the rocker arm and shaft between 0.02-0.05mm. No additional debugging or polishing is required, and installation can be done directly by replacing.
- Stable adaptation: Each rocker arm undergoes multiple factory inspections such as magnetic particle testing, ultrasonic testing, and hardness testing, with no quality issues such as cracks or sand holes.
