35.43 in 80lb Gas Strut Lift Support for Tonneau Cover - Heavy Duty

Our review of these 35.43 in gas struts finds them aimed at truck owners and RV users who need a straightforward, powerful replacement for heavy bed covers and hatches. The single biggest reason to buy is the firm 80lb force per strut, which provides dependable support for heavy tonneau covers and toppers so the lid stays open during loading. Installation is intentionally simple, and the pair format covers both sides of a typical truck bed or hatch in one purchase.

Key Features

• 35.43 in extended length: Provides long travel for deep truck beds and tall toppers, allowing full opening without bottoming out.
• 80lb force per strut: Delivers strong, stable lift and hold for heavy tonneau covers and cab shell windows to prevent accidental collapse.
• Wide compatibility: Works with tonneau covers, pickup bed covers, truck toppers, RV doors and trailer hatch doors for versatile replacement use.
• Quick installation: Swaps out old struts in about five minutes using just a flat screwdriver, so no special tools are required.
• Interchangeable part numbers: Cross-references common OEM codes to simplify matching existing fittings and ensuring proper fit.
• Set of two: Includes both left and right supports so buyers get a matched pair for balanced operation.

Who It's For

This set is best for truck and RV owners who need a durable, high-force replacement for sagging or failed lift supports on tonneau covers, toppers, or hatch doors. It suits people who value easy, no-fuss installation and want a matched pair with clear interchange references for compatibility.

Those who need corrosion-resistant marine-grade hardware or expect extreme long-term durability in harsh salt environments should look elsewhere, since some customers reported mixed durability over time and occasional early failures under heavy use.

How hard are they to install?
Installation is quick and usually requires just a flat screwdriver to click and clip the ball end fittings in place.

Are they corrosion resistant?
They function well for normal use, but some customers reported rust over time, so expect standard corrosion protection rather than marine-grade stainless hardware.
