ARANA 12" 30 lb Gas Struts — 4420 2-Pack 11.97" Extended Lift Supports for Truck Caps & Tool Boxes

These ARANA 4420 gas struts are a 2-piece set of 12-inch, 30 lb (134 N) lift supports designed to replace or upgrade camper shells, truck toppers, toolbox lids, boat hatches and similar lids that need controlled opening and hold-open support.

Built as direct-fit replacements for many factory and aftermarket part numbers, each set includes two gas shocks and a simple installation guide. The struts provide reliable pneumatic assist for lids and hatches where a 22–33 lb supported weight is ideal. Measure your existing struts or check your lid weight before ordering to ensure compatibility, and remember these shocks must be installed before they can be compressed.

How long are these gas struts and how much force do they provide?

The ARANA 4420 struts have a center-to-center extended length of 11.97 inches (305 mm) and a compressed length of 7.88 inches (205 mm). Each shock delivers roughly 30 pounds of push force (134 N), suitable for medium-weight lids and hatches.

• Extended length (center-to-center): 11.97" / 305 mm
• Compressed length (center-to-center): 7.88" / 205 mm
• Rated force: 30 lb (134 N) per strut
• Set includes two shocks plus an installation guide

What applications do these shocks fit and how do I confirm compatibility?

These 12" 30 lb gas springs are commonly used on camper shell side windows, truck toppers, Weather Guard and other toolbox lids, boat hatches and many DIY builds. To be sure of fit, compare the extended and compressed lengths and match interchange part numbers if you have them.

• Interchangeable with numerous part numbers for easy replacement
• Best for lid weights between approximately 22–33 pounds
• Measure existing struts center-to-center before ordering

Are there installation tips or important safety notes I should know?

Install both struts in position before trying to compress them — do not squeeze the shafts by hand prior to installation. Use the included installation guide for correct mounting orientation and hardware; incorrectly mounted struts can bind or fail prematurely.

• Do not manually compress the struts before installing
• Follow the included guide for bracket orientation and torque
• Replace in matched pairs for balanced lift and wear
• Contact ARANA via "Ask Seller" for fitment or installation help

What warranty and customer support does ARANA provide?

Every ARANA product comes with a 365-day replacement support policy to address defects or fitment issues. If you need assistance before or after purchase, use the seller contact options on your order to get timely help or installation guidance.

Who is this for? These ARANA 4420 12" 30 lb gas struts are intended for vehicle owners, contractors and DIYers who need a dependable, mid-force lift assist for small- to medium-weight lids on truck toolboxes, camper shells, boat hatches and toppers. Choose this set if your lid measures within the stated lengths, the supported weight is near 30 pounds (recommended 22–33 lb range), and you want straightforward, interchangeable replacements backed by a one-year replacement policy. If your lid is significantly lighter or heavier, consider selecting a different-pressure strut to ensure safe and durable operation.
