Product Description
The Series III Jaguar XJ12 is a refined, quiet, long-legged cruiser, and its V12 makes it a car people still want to drive, not just look at. If the front seat belts in your XJ12 are frayed, faded or slow to retract, they let down an otherwise elegant interior. This Driver or Passenger Seat Belt from Seatbelt Planet replaces one front belt with a new three-point retractable belt.
What You Get
Seatbelt Planet describes this belt as a three-point retractable lap and shoulder seat belt with an end release buckle. The details are:
- One retractable 3-point lap and shoulder belt
- End release buckle
- Fits the driver or passenger seating position
- Mounting hardware is not included
Because the belt is sold individually, you can replace just the side that needs it. Many owners find the driver's belt has worn far more than the passenger's after years of daily use. If both sides need attention, simply order two.
Plan for Hardware
Hardware is not included with this belt. In many cases the original Jaguar mounting bolts can be reused if they are in good condition and suit the new belt's end fittings. If the bolts are missing, rusty or have been replaced with incorrect fasteners in the past, plan to source proper seat belt hardware before you start. Seat belt bolts should always be the correct grade, length and thread for the anchor point.
Choose from 52 Webbing Colors
Jaguar interiors came in a wide range of leather colors, and a seat belt in the wrong shade stands out immediately. The Webbing Color menu offers 52 colors. Neutral options such as Black, Charcoal, Grey, Silver, Tan, Camel-Tan, Almond, Chestnut, Brown, Dark-Brown, Medium-Beige, Desert-Tan, Ivory, Bone, White and Porcelain cover most original trims. For other interiors there are reds such as Maroon, Red-Wine and Ruby-Red, blues such as Navy, Detroit-Blue and Laguna-Blue, greens, yellows, oranges and patterned options such as M-Stripe and colored edge styles.
A tip for matching: compare your seat leather in daylight rather than under garage lights, and look at the color of the carpet and door cards as well. Many XJ12 owners choose a slightly darker shade than the seats so the belt does not show dirt.
Why Replace the Belts
Seat belts on a car of this age have usually seen decades of sunlight through the large glass areas of the XJ body. UV exposure weakens webbing over time even when it still looks acceptable, and retractors can lose tension or stop locking reliably. A new belt restores proper function and looks right at home in a freshly restored interior. Since this is a car often used for long-distance touring, a belt that retracts smoothly and locks properly is worth having.
Installation Tips
Photograph the old belt's routing and anchor points before removal. Inspect each anchor for corrosion and make sure threads are clean. Keep the webbing flat and untwisted, fit the belt using the correct hardware, and torque each bolt securely. Test the retractor by pulling the belt sharply, and check the buckle latches and releases cleanly. If you are not confident doing the work, have a qualified shop install it.
