The Bilstein B6 1975 Jaguar XJ12 C Rear 36mm Monotube Shock Absorber (part 24-024464) is a rear damper from Bilstein's B6 line. The manufacturer describes B6 shocks as monotube units that provide consistent, fade-free performance through a velocity-sensitive, digressive piston tuned for each application. For a heavy V12 sedan, that means steadier damping over repeated bumps and under hard braking than a worn factory unit, and Bilstein's gas-pressure construction is part of the same platform. Searchers looking for a 1975 XJ12 C rear shock upgrade, a yellow Bilstein B6 monotube for a classic Jaguar V12, or a fade-resistant rear damper for a Series 1 XJ12 will find this part matches that profile.
Application listings cover the 1973–1979 Jaguar XJ12 and differ on which 1975 trims are included, so confirm fitment against your VIN before ordering. Installation is a rear-axle job that calls for a safe lift, stands, and a breaker bar. Jaguar owners on user forums advise against fully tightening the top bolt while the shock is extended, and they recommend seating the bottom mount first. They also warn that lower bolts can seize inside the rubber bushings, so soak them with penetrating fluid well ahead of time. Use forum guidance with care, since much of it comes from later Jaguar models with different rear layouts.
Application listings disagree on which 1975 XJ12 trims are covered, and the 1973–1979 XJ12 range appears in several listings. Check the manufacturer's application data against your VIN before ordering.
Jaguar owners on user forums advise against tightening the top bolt while the shock is fully extended. They recommend waiting until the bottom mount is in place, and confirming that the spacer tube sits inside the eye of the shock.
Owners on user forums report that lower bolts can seize into the rubber bushings. They suggest soaking the bolts with penetrating fluid in advance, and some use gentle heat on the inner metal of the bushing before removal.
This is a moderate-difficulty job for a home mechanic with a safe lift or jack stands. Plan on a socket set, a long extension, a breaker bar, penetrating fluid, and a jack. Expect seized fasteners, especially at the lower mount, and budget extra time if the bushings are worn. If you need to remove the spring, you will also need spring compressors. Forum advice on rear shock swaps often comes from later Jaguar models with different suspension layouts, so check the factory service information for the 1975 XJ12 before you start.
