Jeep Wrangler Back Glass Lift Supports
Jeep Wrangler Back glass lift supports
Back glass lift supports for your Jeep Wrangler start at $6.95. AutoBuffy stocks 35 units from FCS, Monroe, and Mopar. These gas-charged struts hold the rear hatch or back glass open while you load cargo. When they fail, the glass drops unexpectedly, creating a safety hazard and making the cargo area nearly inaccessible.
Signs your Jeep Wrangler needs new back glass lift supports
- Back glass falls shut on its own instead of staying open at full extension
- Hatch rises only partway and requires you to prop it open manually
- Noticeable resistance or grinding when lifting the glass — the strut is binding rather than assisting
- Visible oil film or wet residue on the strut body, indicating the gas seal has failed
- Loud popping or creaking noise when opening or closing the back glass
- Strut body is visibly bent, corroded, or the end fittings have separated from their ball-stud mounts
Which back glass lift support should you buy for your Jeep Wrangler?
The most important decisions are whether the replacement matches the OE extended and compressed lengths for your Wrangler, and whether you want a direct OE-equivalent or an upgraded heavy-duty unit. Lift supports are typically sold individually or in pairs — if one has failed, the other is usually close behind, so replacing both at the same time is strongly recommended.
OE-Replacement (Standard)
Best for
Drivers who want factory performance restored
What you get
Matched gas charge and length to original specs; straightforward swap with no adjustments needed
Heavy-Duty / Extended-Cycle
Best for
High-use vehicles, commercial use, or extreme climates
What you get
Reinforced seals and higher-cycle rating for longer service life; same fitment as OE
Sold as a Pair
Best for
Complete restoration of both supports at once
What you get
Matched units from the same production batch; eliminates uneven lift force that causes the glass to rise crooked
Left or Right Individual Unit
Best for
Replacing only a mechanically failed strut on a recently serviced vehicle
What you get
Single strut for cost savings; confirm which side is damaged before ordering

Replacing back glass lift supports on a Jeep Wrangler
Easy⏱ 30–60 minutesTrim clip removal tool or small flat-blade screwdriverNeedle-nose pliers (for retaining clip style)Safety prop rod or a second person to hold the glassGloves (glass edge protection)
Prop the back glass fully open and secure it before touching the old struts. Most lift supports snap onto ball studs and are removed by prying the socket end off the stud with a trim tool — no drilling or cutting required. Install the new struts by pressing the socket ends firmly onto the ball studs until they click, then test the glass through several full open-and-close cycles to confirm proper operation.
Frequently asked questions
How much does it cost to replace back glass lift supports on a Jeep Wrangler?
Parts start at $6.95 at AutoBuffy. Because the job typically requires no special tools and takes under an hour, many owners do it themselves and pay only for parts. Shop labor, if used, usually adds one hour of shop time. Replacing both supports in a single visit keeps total cost down.
How long do back glass lift supports last on a Jeep Wrangler?
Most lift supports last several years under normal use, but lifespan varies with climate, usage frequency, and whether the vehicle is stored outdoors. Cold weather temporarily reduces gas pressure and accelerates seal wear. Units on high-use vehicles or those in harsh climates often need replacement sooner than those on lightly driven cars.
Can I drive my Jeep Wrangler with a failed back glass lift support?
Yes, a failed lift support does not affect driveability. However, the unsupported glass can drop suddenly and cause injury or damage the glass and trim. Until the struts are replaced, use a prop rod or keep the hatch closed. Avoid leaving the glass unattended in the open position.
Do I need to replace both back glass lift supports at the same time on my Jeep Wrangler?
Replacing both at the same time is strongly recommended. Lift supports age together, so if one has failed the other is likely near the end of its service life. Mismatched struts — one new, one worn — create uneven lifting force that can cause the glass to rise at an angle and stress the hinges.
How do I know if the lift support or the back glass hinge is causing the problem on my Jeep Wrangler?
Manually prop the glass fully open and inspect each strut. If the strut body is oily, visibly collapsed, or you can compress it by hand with little resistance, the strut has failed. If the strut feels firm but the glass still sags, inspect the hinge mounting points and weld areas for cracks or looseness before ordering parts.
Are aftermarket back glass lift supports as good as OEM for a Jeep Wrangler?
Quality aftermarket lift supports from reputable brands match OE extended length, compressed length, and gas charge. The key is confirming the correct part number for your specific Wrangler trim and build date, since variations exist within the same generation. Brands like FCS, Monroe, and Mopar are engineered to OE fit and function standards.
