2009 Ford Mustang Shelby GT500KR �€" 540 HP, Numbered Build, Vista
Blue, 6-Speed Manual Why This Car Is Special The 'KR' in GT500KR
stands for King of the Road �€" a name that dates back to 1968,
when Shelby introduced the original GT500KR as the top-of-the-line
muscle car in the Mustang lineup. Ford and Shelby revived that
designation for 2008 and 2009 as a limited-production variant that
sat above the standard GT500 in every meaningful way. The 2009 Ford
Mustang Shelby GT500KR was not simply a GT500 with appearance
upgrades. It was a purpose-built package developed jointly by
Ford's Special Vehicle Team and Shelby Automobiles, with a
factory-rated 540 horsepower �€" up from the GT500's 500 �€"
achieved through a combination of a Ford Racing cold air intake,
revised supercharger calibration, and a specifically tuned version
of the 5.4-liter supercharged V8. Production for the 2009 model
year was tightly limited, making this one of the rarer
S197-generation Mustangs to come to market in any condition, let
alone in the documented, well-preserved state this example
represents. Each GT500KR was assigned a numbered Shelby build
plaque, which is present on this car, confirming its place in the
production registry. The car you are looking at carries that
history intact �€" matching Vista Blue paint, black leather
interior with Carroll Shelby signature headrests, the full carbon
fiber aero package, and a clean undercarriage that tells the story
of a car that has been cared for from the beginning. Features List

heart of the 2009 Ford Mustang Shelby GT500KR is a 5.4-liter,
aluminum-block, supercharged V8 producing 540 horsepower and 510
lb-ft of torque as rated at the flywheel. The supercharger is an
Eaton TVS unit, and the GT500KR's output advantage over the
standard GT500 came through the Ford Racing cold air intake system
�€" visible and correctly fitted in the engine bay �€" along with
recalibration of the supercharger system and engine management. The
engine bay on this example is clean and well-presented, with no
evidence of leaks, hacking, or deferred maintenance. The Ford
Racing strut tower brace is in place, adding chassis rigidity at
the front end, which is particularly relevant given the torque this
engine produces through the drivetrain. Power is sent to the rear
wheels through the Tremec TR-6060 6-speed manual transmission. The
TR-6060 was a significant upgrade over the TR-3650 used in earlier
Mustangs �€" it was designed specifically to handle the torque
output of the supercharged 5.4, and it paired with a short-throw
shifter on the GT500KR for reduced throw distance between gates.
Behind that sits a 3.73 limited-slip differential, which gives the
car strong off-the-line bite and keeps both rear tires working
together under hard acceleration. The SVT-tuned suspension was set
up to balance straight-line stability with cornering capability,
and Brembo disc brakes �€" standard equipment on the GT500KR �€"
provide the stopping power the performance numbers demand. The
undercarriage photos confirm a clean, rust-free floor pan and
subframe, consistent with a car that has not been abused or stored
improperly. Interior Inside, the 2009 Ford Mustang Shelby GT500KR
is finished in black leather throughout. The front seats carry
