Euplokeer 15in Gas Struts for Sungtop Leer Camper Topper — Qty 2, ML33-40/SL13-40 Compatible, Easy Install

These two Euplokeer 15-inch gas struts replace worn lift supports on Sungtop, Leer, ARE truck camper toppers and similar RV storage hatches.

If your camper shell, topper cap, motorhome storage door, boat seat or engine hatch no longer stays open or feels heavy, these ML33-40 / SL13-40-compatible gas springs restore smooth, reliable support. The kit includes two identical 15.0 inch extended-length shocks that install with only a flat-head screwdriver and match common OEM interchange numbers for easy fitment.

Will these gas struts fit my Sungtop or Leer camper topper?

They’re designed to match many common OEM numbers used by truck caps and camper shells, but fitment depends on matching the original extended length and force rating. Check your old cylinder for the interchange number and measure the extended length to confirm compatibility.

• Extended length: 15.0 inches
• Included quantity: 2 gas struts
• Compatible OE references include ML33-40, SL13-40, LGP6-150-40 and many similar codes
• Simple install: only a flat-head screwdriver required

How do I choose the correct replacement gas spring?

Selecting the right strut means matching three things: the OEM interchange number stamped on your old shock, the extended length measurement, and the required push/pull force. If any of these differ significantly, the strut may not lift or hold the hatch correctly.

• Locate OEM number on old cylinder and compare to listed interchanges
• Measure extended length end-to-end (this model = 15.0 in)
• Match pound-force rating or choose a close equivalent
• Contact Euplokeer support if unsure about fit

What surfaces and applications are these lift supports suitable for?

These gas shocks are intended for camper toppers and related uses where controlled lift and hold are needed. They work well on truck camper caps, RV storage doors, marine seats, engine hatches and similar panels that require gas spring assistance.

• Truck camper topper caps (Sungtop, Leer, ARE)
• RV/motorhome storage doors and lids
• Boat seats and small hatch covers
• Lightweight engine or access hatches

How easy is installation and what tools are required?

Installation is straightforward and designed for DIY replacement: the strut uses common ball-stud end fittings and removes with a flat-head screwdriver. No special tools or professional services are typically necessary unless your mounting brackets are rusted or nonstandard.

• Tool needed: flat-head screwdriver
• Mount type: standard ball-stud attachments
• Time estimate: usually under 30 minutes for both sides
• Inspect brackets and studs for corrosion before fitting

Who is this for: Vehicle owners, DIY mechanics and RV enthusiasts who need dependable replacement lift supports for 15-inch camper toppers, truck caps and small hatch lids. If you have a Sungtop, Leer or compatible topper and your existing shocks are weak, leaking, or no longer hold the door open, this two-piece Euplokeer set offers an affordable, easy-to-install option backed by responsive customer support and a 15-month exchange policy.
