TadaMark rear hatch lift support struts are a direct-fit pair of gas springs engineered to replace worn tailgate shocks on Dodge Challenger models from 2008 through 2020.

This pair of lift supports (two pieces) restores smooth, controlled opening and secure hold of the Challenger’s rear trunk lid. Designed to match the original equipment (OE) geometry, they provide the correct extended and compressed lengths for a precise fit, straightforward swap-out installation, and dependable daily operation. Every detail below helps you confirm fitment, understand benefits, and decide if these are the right replacement parts for your vehicle.

Will these lift supports fit my Dodge Challenger?

Yes — these struts are specified to fit Dodge Challenger model years 2008 through 2020 and reference OE numbers for cross-checking. They are manufactured to match the factory mounting positions for the left and right rear trunk locations, making them suitable direct replacements.

• Compatible years: 2008–2020 Dodge Challenger
• Placement: rear trunk, left and right
• Reference numbers: 04589645AA, 6657, 04589645AB for verification
• OE-quality design promises correct alignment and fit

How do the dimensions affect installation and operation?

The listed extended and compressed lengths determine how the strut mounts align when the trunk is open and closed. Matching those dimensions ensures the trunk opens to the intended height and stays held without sagging; incorrect lengths can cause improper lift or excessive force.

• Extended length: 11.38 inches for fully open position
• Compressed length: 7.63 inches when closed
• Proper dimensions reduce stress on hinges and latches
• Direct-fit design simplifies swap with original parts

What are the benefits of replacing both struts together?

Replacing the pair at once preserves balanced opening and equalized wear, preventing uneven stress on the trunk lid and hinges. New matched struts provide predictable damping and holding power so the hatch won't drift or slam unexpectedly.

• Balanced support for stable opening and closing
• Reduced hinge and latch stress prolongs related components
• Restores factory feel and safety when accessing trunk
• Two-piece kit covers both left and right sides for consistency

How difficult is installation and what tools are needed?

Installation is typically straightforward for anyone with basic hand tools and a little mechanical comfort. Because these are OE-quality replacements with the same mounting points, most installs require removing clips or bolts and swapping the old struts for the new, one side at a time.

• Common tools: pliers, trim clip tool or small wrench
• Follow safe support procedure for the open trunk during replacement
• No special adapters required when matched to OE reference numbers
• Professional installation optional if you prefer not to work on the vehicle

Who is this for: Owners of Dodge Challenger models from 2008 through 2020 who are experiencing weak or failed trunk lift supports, uneven or heavy opening, or visible oil/air leaks around the current struts. This TadaMark two-piece kit suits DIY enthusiasts wanting a direct OE-style replacement, repair shops supplying a reliable aftermarket option, and anyone seeking to restore safe, controlled operation of the rear hatch without custom modification.
