2007-2015 Jaguar XK, XKR & XKR-S Liftgate Struts: Diagnosis and DIY Replacement
This guide covers the common failure symptoms of liftgate supports on the Jaguar XK, XKR, and XKR-S coupe, and provides a step-by-step replacement guide.
- These lift supports are for 2007-2015 Jaguar XK, XKR, and XKR-S **Coupe models only** and will not fit convertibles.
- The primary symptom of failure is a liftgate that is heavy to lift and will not stay open on its own, which is a significant safety hazard.
- Replacement is a very easy, 15-minute DIY job requiring only a small flathead screwdriver.
- Always replace struts in pairs and ensure the heavy liftgate is securely propped open before starting the repair.
Symptoms of Failing Liftgate Supports
Failure of the liftgate supports on the 2007-2015 Jaguar XK, XKR, and XKR-S is a common issue that typically happens gradually. Because these are simple pneumatic struts, there are no electronic fault codes associated with their failure. The symptoms are entirely physical.
- Liftgate Won't Stay Open: This is the most common and obvious symptom. The struts lose pressure and can no longer support the weight of the hatch, causing it to slowly drift down or slam shut unexpectedly. This is a major safety hazard.
- Heavy Liftgate: You will notice that lifting the rear hatch requires significantly more physical effort. When the struts are working correctly, they assist with the lifting motion, making it feel relatively light.
- Slow or No Automatic Lift: While these vehicles are not designed for the hatch to fully open on its own, healthy struts should provide a slight initial lift of an inch or so when the release is triggered, making it easy to then lift manually. When the struts are weak, the hatch may only unlatch without lifting at all.
Warning: A failing liftgate support can cause the heavy hatch to fall unexpectedly, leading to serious injury. If your liftgate will not stay open on its own, prop it open securely with a sturdy object like a wooden stick before accessing the trunk.
Known Issues, TSBs, and Recalls
As of early 2026, there are no specific recalls or technical service bulletins (TSBs) issued by Jaguar or the National Highway Traffic Safety Administration (NHTSA) for the liftgate lift supports on the 2007-2015 Jaguar XK, XKR, or XKR-S. Failure of these parts is considered a normal wear-and-tear item. Recalls for this vehicle range have been issued for other components such as lighting, suspension, and tire pressure monitoring systems, but not the hatch struts.
Pro Tip: While there are no official bulletins, owner forums frequently discuss the premature failure of these struts. Some owners suggest applying a silicone lubricant to the shiny strut shaft to keep it clean and moving smoothly, which may help extend its life.
Buying a Used Liftgate Support: What to Check
While buying a used part can be a cost-effective solution, liftgate supports are a wear item with a finite lifespan. A used strut from a 10-year-old vehicle may not have much life left. However, a good used OEM part can still be a better choice than a low-quality new aftermarket part.
- Physical Inspection: Before purchasing, inspect the strut body for any signs of oil leakage or residue. A wet or oily film around the seal where the thin rod enters the thicker cylinder is a clear sign of failure. The strut should be dry.
- Check the Donor Vehicle: If possible, find out the mileage and age of the vehicle the part came from. A lower-mileage, later-model-year donor is always preferable.
- Verify Compatibility: Ensure the part is from a Coupe model. The struts for the convertible are completely different and will not work. 🎬 See how quickly you can swap out these trunk struts. The OEM part number is 6W83-406A10AC.
- Test the Pressure (If Possible): While difficult, if you can handle the part, try to compress it by hand. A healthy strut should be nearly impossible for a person to compress. If it offers little resistance, it is no good.
Cost of Replacement
The cost to replace liftgate supports can vary significantly based on the parts you choose and whether you do the work yourself.
| Item | Estimated Cost |
|---|---|
| New OEM (Jaguar Dealer) | $100 - $150+ per strut |
| New Aftermarket (e.g., Stabilus, TRQ) | $45 - $80 for a pair |
| Used OEM | $20 - $50 for a pair |
| Shop Labor | $42 - $77 |
Liftgate Support Replacement Guide (DIY)
Replacing the liftgate supports is a very simple DIY task that requires minimal tools and time. It is highly recommended to replace them in pairs to ensure even pressure and longevity.
- Difficulty: 1 out of 5
- Time: 10-15 minutes
- Tools Needed: Small flathead screwdriver.
Step-by-Step Instructions:
- Prop the Liftgate Open: This is the most critical step. Have a friend hold the heavy liftgate or securely prop it open with a piece of wood or a strong pole. The old struts will not support it once one is removed.
- Remove the Old Strut: At the top and bottom of the strut, you will see a small metal clip that holds the strut onto a ball stud. Use a small flathead screwdriver to gently pry this clip outwards. You do not need to remove the clip completely.
- Pop the Strut Off: Once the clip is released, the strut will pop off the ball stud. Do this for both the top and bottom ends and remove the old strut. Note the orientation (thicker cylinder body is typically down). 🎬 Watch this step-by-step walkthrough of the replacement process.
- Install the New Strut: The new struts simply snap onto the ball studs. There is no need to pry the clips on the new parts. Align the end of the new strut with the ball stud and give it a firm push. It will click into place.
- Repeat on the Other Side: It is best to replace one strut completely before moving to the other side.
- Test: Carefully remove your prop and test the liftgate's operation. It should now hold itself up and feel much lighter to lift.
Compatibility Warning: These lift supports (part number 6W83-406A10AC) are for the 2007-2015 Jaguar XK, XKR, and XKR-S Coupe models ONLY. They will not fit convertible vehicles, which use a different part for the trunk lid.
Frequently Asked Questions (FAQ)
Can I replace just one liftgate support?
It is strongly recommended to replace both supports at the same time. When one fails, the other has been doing all the work and is likely worn as well. Replacing only one can cause the new strut to wear out prematurely.
Are aftermarket struts as good as OEM?
For a simple part like a gas strut, high-quality aftermarket brands like Stabilus (who are often the original equipment manufacturer) or StrongArm are considered to be as good as, or even better than, the dealer part and are available at a much lower cost. Cheaper, unbranded options are also available but may have a shorter lifespan.
Will new struts make my trunk open automatically?
No. The factory struts are not designed to fully open the heavy liftgate on their own. They are designed to assist the lift and hold it open. Some owners have experimented with stronger struts, but this can make the hatch difficult to close and may put extra stress on the latch mechanism and mounting points.
What is the correct orientation for the struts?
Typically, gas struts are installed with the thicker cylinder body at the bottom and the thinner piston rod at the top. This orientation helps keep the internal seals lubricated. The replacement video for the Jaguar XK confirms this orientation, with the cylinder body mounted to the lower ball stud.
