Intended for compatible 1964–1966 Ford Mustang applications. Verify whether the arm is LH, RH, or designed for either side. Confirm whether the ball joint is included. Verify whether bushings and the control-arm shaft are preinstalled. Compare mounting-hole spacing with the original suspension. Check the condition of the shock tower and mounting points before installation. Inspect the spring perch, lower control arm, tie rods, and spindle while servicing the front suspension. Existing alignment shims should be documented before disassembly. Suspension geometry may require adjustment after replacement. Modified or performance suspension setups may require different control arms. Professional wheel alignment is recommended after installation.

005Counter questions

Asked about this part

What is this product?
It is an upper control arm assembly for compatible 1964–1966 Ford Mustang front suspension applications.
What years does it fit?
It is intended for 1964, 1965, and 1966 Ford Mustang applications, subject to the exact suspension configuration.
Where is this part installed?
It installs in the front suspension at the upper control-arm position.
What does the upper control arm do?
It helps locate the front wheel and spindle while allowing controlled suspension movement.
Can it cause loose steering?
Worn bushings or ball joints in the assembly can contribute to loose or inconsistent steering.
Is it suitable for a show car?
Yes, if the design and finish match the desired restoration level.
Is this a factory-original Ford part?
Not unless the listing specifically identifies it as genuine Ford or NOS.
Is it an aftermarket replacement?
Yes, unless otherwise stated.
Is this sold individually or as a pair?
Verify the exact listing quantity.
Can the left and right upper control arms be the same?
Some applications may use similar or interchangeable assemblies, but side-specific fitment should be verified.
Should I replace both sides together?
It is often a good idea when both sides have similar age or wear.
Can I replace only one side?
Yes, if the opposite side is still in good condition and fitment is correct.
Can the original shims be reused?
They may be reused if in good condition, but final alignment must still be performed.
Can the control arm be installed by a DIY owner?
Yes, if the installer is experienced with suspension work and follows safe procedures.
Should the battery be disconnected?
It is not usually necessary for this suspension repair, but general workshop safety should still be followed.
Should bushing bolts be tightened at normal ride height?
For bonded rubber bushings, this is often important to avoid preload; follow the specific installation procedure.
Are grease fittings included?
They may be, depending on the ball joint or assembly design.
What type of grease should be used?
Use a chassis or suspension grease compatible with the supplied joints.
Can they eliminate all steering play?
No. Steering play can also come from tie rods, idler arms, steering boxes, wheel bearings, and other components.
What should I inspect first?
Check the arm for bends, cracked welds, damaged bushings, ball-joint condition, shaft straightness, threads, and finish damage.
What should I verify before ordering?
Confirm the 1964–1966 Ford Mustang model year, LH / RH or universal position, control-arm dimensions, shaft and bushing design, ball-joint configuration, mounting-hole spacing, spring-perch relationship, suspension modifications, included hardware, and package quantity before purchase.
