Product Details

The StrongArm 6428 Trunk Lid Lift Support is a pressurized gas strut designed to provide smooth, reliable support for automotive trunk lids and hatches. This precision-engineered cylinder uses compressed gas to assist in lifting and holding your trunk open, eliminating the need for manual support and preventing unexpected closure.

Key Features:

  • Custom engineered to meet or exceed OEM specifications
  • Pressurized gas cylinder design for consistent lifting force
  • Manufactured beyond industry standards for extended service life
  • Smooth operation throughout the entire range of motion
  • Direct replacement for worn or failed factory lift supports

Important Installation Note: Lift supports should always be replaced in pairs to ensure balanced operation and safe, reliable support of your trunk lid or hatch. Replacing only one strut can result in uneven lifting force and premature failure.

StrongArm lift supports are built for durability and long-lasting performance in automotive applications. Each unit is designed to provide the precise amount of force needed to support your vehicle's trunk lid while maintaining smooth operation over thousands of cycles.

Super pricing, fast shipments, good selection they have it all.

My second time ordering from Autoplicity. I price shop online and Autoplicity had the lowest price both times. Fast ship with email notifications. Autoplicity will now be my "First" site I go to for my auto accessories. Great job Autoplicity.

Great prices, quick shipping, customer service a bit difficult to reach. But, after reaching customer service, issue was resolved without a problem.

I hope the product is as good as the speed I received the item. I even made a mistake on my order, and it still arrived fast. Thanx, will do business with again.

Order arrived quickly and was exactly as described. Great prices and service!

Very easy to talk to on the phone and excellent service.
