Product Details

The StrongArm 4521 Trunk Lid Lift Support is a precision-engineered pressurized cylinder designed to provide smooth, reliable support for automotive trunk lids and hatches. This gas-charged strut delivers consistent lifting assistance, making it easier to open and safely hold your trunk lid in the raised position.

Key Features:

  • Custom engineered to meet or exceed OEM specifications
  • Pressurized gas-charged cylinder for smooth, controlled operation
  • Manufactured beyond industry standards for extended service life
  • Direct replacement for worn or failed original lift supports
  • Suitable for automotive trunk lids, hatches, and liftgate applications

Installation Note: Lift supports should always be replaced in pairs to ensure balanced support and safe operation of your trunk lid or hatch. Replacing only one side can result in uneven lifting force and potential safety issues.

StrongArm lift supports are built to deliver smoother operation and longer-lasting performance than standard replacement struts, restoring proper trunk function and convenience to your vehicle.

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.

Excellent low price, super fast shipping, and great communication. Top notch seller. Recommend highly!!

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

Always have what I need for the lowest price with free or cheap shipping.

good and fast
