Common symptoms in bad rocker arms include cracks or wear, strange noises or loose etc.

1.When you start the engine you will hear the Clicking or Ticking Noises.

2.Weak Engine Performance or Stalling.(poor acceleration , decreased power and affect the life of the engine.)

3.Engine Light On (DTC codes will be P2646, P2647 etc.)

Why Replace?

1.This valve lifter can help you resolve problems such as poor acceleration, decreased power or abnormal noise.

2.Please replace it as soon as possible to avoid further damaging your engine.

What's the Rocker arms & How Does It Work?

1.Rocker arms are reciprocating lever used in an internal combustion engine. They are typically located between the intake and exhaust valves and pushrods which are connected with crankshaft below the engine.

2.When the crankshaft rotates it cause up and down movement of the pushrods, then the pushrods pushed and pulled the rocker arm to rock up and down which cause opening and closing of the intake and exhaust valves. Then power can flow from the combustion chamber of engine through various parts to the wheels to put the vehicle in motion.

3.The broken and loose rocker arm cause poor performance of the engine, the engine will be enable to take the full load of the vehicle and in severe cases engine failed to start.

What's the Hydraulic Lifter & How Does It Work?

1.A Hydraulic Lifter, also known as valve lifter or hydraulic lash adjuster, is a device for maintaining zero valve clearance in an internal combustion engine.Hydraulic Lifter keeps the valve healthy and protects from an engine's normal thermal expansion process.

2.The hydraulic lifter was designed to allow the valve train to operate with zero clearance—leading to quieter operation, longer affect the life of the engine, and eliminating the need for periodic adjustment of valve clearance.

3.Replace Your Bad Hydraulic Lifters On Time.

We had a misfire on cylinder on our 2005 tahoe with a 5.3 ls motor and after installing this lifter the problem was gone. Now our tahoe is running great again!
