Product Details

The StrongArm 6143 is a precision-engineered trunk lid lift support designed to provide smooth, reliable operation for your vehicle's trunk or deck lid. This gas-charged strut uses pressurized cylinder technology to safely support and assist in opening and closing your trunk lid, eliminating the need for manual propping and preventing sudden closure.

Key Features:

  • Custom-engineered design manufactured to exceed industry standards
  • Pressurized gas cylinder construction for consistent, reliable performance
  • Smooth operation throughout the lift cycle for improved user experience
  • Durable construction designed for extended service life
  • Direct replacement for worn or failed OEM lift supports

Important Installation Notes:

  • Lift supports should always be replaced in pairs to ensure balanced, safe operation
  • Replacing both supports simultaneously prevents uneven wear and potential safety hazards
  • Proper installation ensures optimal trunk lid support and prevents damage to your vehicle

StrongArm lift supports are trusted by professional technicians and DIY enthusiasts alike for their quality construction and dependable performance. When your original trunk struts lose pressure and fail to hold your trunk open, the StrongArm 6143 provides a reliable replacement solution.

Placed an order with Adam on Monday, Nov 28th (#601). Very satisfied with Adam's technical knowledge and received my product on Nov 29th. The product is exactly as he represented and, because of this great customer service, I will place future orders.

I ordered a WeatherTech cargo liner from Autoplicity after finding the product almost $40 cheaper than anywhere else. Usually I'm suspect of the one company with a very low price but the high number of reviews gave me enough comfort to order. The product came in a large box and was shipped for a very reasonable price and arrived in four business days. The product is as described and I couldn't be happier. I will definately keep them in mind for future orders.

I had just bought a body lift and spacer for truck, and sure enough it all came in a timely fashion. This site is a great one to check out if you need any parts. Easy access, quick processing, I believe this is the,site ill use fot now on.

Order was quickly processed, good price too.

The item arrived fast and in good condition. There however seems to be a glitch with the scale the first time we weighed something. After we shut it off and then back on it seemed to be OK.

Cheapest price I found! And super speedy deliver! Impressed!

Great service. Shipped out the day after I ordered it...plus it was the cheapest of the competition.

Greatest web site i have been to in a long time. Great products, affordable prices, and my item wa shipped fast. I would highly recommend and i will be back.
