Euplokeer 21577-002 15.3" Gas Strut Pair for Truck Topper Camper Shells — OE Interchange, Controlled Lift

Euplokeer 21577-002 is a pair of 15.3-inch gas struts designed to replace worn or broken lift supports on compatible truck toppers, camper shells and rear windows.

These replacement gas shocks are built to match the common OE interchange numbers used on many Leer and Snugtop-style caps and toppers. Sold as a set of two, each 15.3-inch strut aims to restore smooth, controlled opening and holding of rear windows and tailgates where the original cylinders have lost pressure. Before ordering, verify the part numbers and extended length on your existing struts to ensure a correct fit.

How do I know if the 15.3in Euplokeer strut fits my camper shell?

Confirming fit is a simple three-step check: compare the OEM interchange numbers, measure the extended length of your current lift support, and check the pound-force rating if available. This model corresponds to interchange numbers 21577002 and 21577-002, and it’s intended for specific Leer/Snugtop-style applications rather than every brand on the market.

• Compare OE numbers: 21577002 or 21577-002.
• Measure extended length: 15.3 inches must match your old strut.
• Verify pound-force or lift rating when possible for equivalent performance.

What tools and steps are needed to install these gas shocks?

Installation is designed to be straightforward and requires only basic tools: a flat-head screwdriver to pop off the retaining clips and replace the ball-socket ends. The Euplokeer struts come as direct replacements and clip onto existing ball studs if your topper uses that common mounting style.

• Tools: flat-head screwdriver (no special tools required).
• Mounting: snaps onto existing ball studs or brackets.
• Time: typically 10–20 minutes to replace both sides on most shells.

What performance should I expect from these replacement gas shocks?

Once installed, the new cylinders should provide controlled lift and positive holding force comparable to the original springs when matched correctly. They restore smooth opening, prevent sudden drop, and reduce strain on hinges and the shell structure when the specified specifications align with your original parts.

• Controlled opening and steady hold at full extension.
• Reduced stress on hatch hinges and seals.
• Sold as a pair for balanced operation on dual-support setups.

How long do Euplokeer gas struts last and what support is offered?

Durability depends on use, environment, and proper fit, but these gas shocks are manufactured for typical automotive accessory lifecycles. Euplokeer offers responsive customer support and a 15-month product exchange program to address premature failure or fitment concerns.

• 15-month exchange service for eligible issues.
• 24-hour email support from the Euplokeer team.
• Recommended: inspect periodically for leaks, corrosion, or diminished lift.

Who is this for: This replacement set is meant for pickup owners and DIY mechanics who need an affordable, direct-fit solution for Leer or Snugtop-style camper shells, toppers, or rear windows that use 15.3-inch lift supports. If you have the correct OEM interchange number and matching extended length, these Euplokeer struts provide a quick swap to regain safe, controlled hatch operation without a dealer visit.
