Detailed Description of the StrongArm 6690

The StrongArm 6690 hood lift support is a precision-engineered gas strut designed to replace factory hood supports on select Mercedes-Benz SLK models. Its steel outer cylinder with a black finish offers corrosion resistance and durability. The 19.0 mm diameter cylinder and 8.0 mm inner shaft diameter provide the necessary strength and rigidity. Both ends feature 10mm nylon ball sockets, ensuring a secure and vibration-resistant connection to the hood and frame. The 11.0-inch stroke length allows smooth and controlled hood movement, while the maximum force of 73 lbs supports the hood safely in the open position. Rubber and Teflon materials inside the assembly reduce friction and wear, contributing to long service life.
