Product Details

The StrongArm 4539 is a precision-engineered trunk lid lift support designed to provide smooth, reliable operation for your vehicle's trunk or hatch. This pressurized gas cylinder is custom-manufactured to exceed industry standards, ensuring consistent lifting force and extended service life.

Key Features:

  • Pressurized gas cylinder design for smooth, controlled trunk lid movement
  • Custom engineered to meet or exceed OEM specifications
  • Built to industry-leading standards for durability and longevity
  • Designed for reliable performance in automotive trunk and hatch applications
  • Manufactured by StrongArm, a trusted name in lift support solutions

Important 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 support can result in uneven lifting force and potential safety issues.

StrongArm lift supports are engineered to restore your trunk lid to proper function, providing the effortless opening and secure holding that your vehicle had when new.

Excellent customer service....<br>fast delivery<br>and good quality parts<br><br>

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!!

Very easy and website was quick to let me know if a part would or would not fit my car - very helpful.

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

I needed a few small XRP fittings for our NHRA Top Alcohol Dragster, I had called XRP and even a "pro racer discount" the price was ridiculous; couple this with their ridiculous shipping/handling charge I had to go elsewhere. I typed in the XRP part number into Google and found Autoplicity, twice as many pcs. as I was planning on ordering and with shipping it was cheaper than one fitting from XRP direct. I will be checking Autoplicity anytime I'm ordering something from this day on, everything about the transaction was smooth and simple. I just got my tracking number today and the stuff is on its' way. Thanks for making this transaction so easy and not robbing your customers on something as frivolous as "handling".<br><br>Respectfully,<br>Brandon Booher<br>NHRA TAD #34
