1964 Comet Suspension Parts from MAC's: What You Need to Know

Restoring a 1964 Mercury Comet’s suspension is a rewarding project, but finding the right parts can be tricky. MAC’s Custom Auto Parts (commonly referred to as MAC’s) is a well-known supplier for classic Ford and Mercury vehicles, including the 1964 Comet. Their suspension components range from complete front-end rebuild kits to individual bushings, springs, and shocks. This article covers the essential suspension parts for the 1964 Comet, what MAC’s offers, and how to choose the best components for your car’s needs.

Understanding the 1964 Comet Suspension System

The 1964 Comet shares its platform with the Ford Falcon and uses a conventional front suspension design with upper and lower control arms, coil springs, and a solid rear axle with leaf springs. Over time, rubber bushings dry out, ball joints wear, and springs sag. Restoring the suspension to factory specifications or improving it for better handling requires replacing multiple parts.

Front Suspension Components

• Upper and lower control arms with bushings and ball joints
• Coil springs (varying rates for different engine sizes)
• Front shocks (twin-tube design)
• Stabilizer bar (sway bar) with bushings and end links
• Strut rods (if equipped)

Rear Suspension Components

• Leaf springs (2- or 3-leaf sets depending on model)
• Rear shocks
• U-bolts and spring plates
• Rear sway bar (optional on some models)

Common Suspension Issues on the 1964 Comet

Owners often encounter sagging front springs, loose steering from worn idler arms, and a bouncy ride due to weak rear leafs. Rusted or broken U-bolts are also common. When sourcing parts from MAC's, it's important to cross-reference your car's original equipment or VIN to ensure compatibility.

MAC's Suspension Parts Options

MAC's offers a range of suspension parts specifically for the 1964 Mercury Comet. Their catalog includes both reproduction OEM-style parts and some upgraded components. Here’s a breakdown:

Front End Rebuild Kits

MAC's sells full front end kits that include ball joints, tie rod ends, idler arm, pitman arm, and bushings. These kits are available with rubber or polyurethane bushings. The rubber bushings maintain a stock ride, while polyurethane provides firmer handling but transmits more road noise. For a daily driver, rubber is generally preferred; for a performance-oriented build, polyurethane may be better.

Coil Springs

MAC's offers coil springs in standard and heavy-duty options. Standard springs match the original ride height for six-cylinder models, while heavy-duty are for V8 cars or those with air conditioning. Be aware that springs from different suppliers may vary in rate and free height. MAC's springs are known for being within 0.5 inches of stock height once settled.

Leaf Springs

Rear leaf springs are available in single or multi-leaf configurations. MAC's repros are close to factory specs but may require minor adjustments for perfect alignment. Always replace the related U-bolts and shackle bushings when doing leaf springs.

Shocks and Steering Components

MAC's stocks gas-charged shocks that are direct replacements for the original. They also carry tie rod sleeves for those wanting to adjust toe-in without replacing entire tie rods. Steering boxes can be rebuilt, but MAC's sells a remanufactured unit if your original is beyond repair.

Installation Tips for DIYers

Replacing suspension on a 1964 Comet is a medium-difficulty job. Here are a few practical notes:

• Use a spring compressor for front coils—do not attempt to disassemble without one.
• Support the car on jack stands correctly; the frame is sturdy but rust-prone.
• When replacing control arm bushings, note that the lower arm uses a unique offset bushing to align caster. MAC's includes the correct bushing in their kits.
• For rear leaf springs, soak the U-bolt nuts with penetrating oil a day before. They often rust and break.
• After installation, get a professional alignment. The Comet’s front shims allow camber and caster adjustments.

Comparing MAC's to Other Suppliers

While MAC's is a popular choice, other suppliers like Classic Industries, Mustang Steve, or local parts stores can also provide parts. MAC's advantages include:

• Complete kits that save you from buying separate pieces.
• Accurate reproduction of factory parts for a stock restoration.
• Customer service that knows the nuances of early Ford suspension.

However, some enthusiasts prefer to buy individual parts (e.g., Moog ball joints) from national auto parts chains for easier warranty returns. If you need immediate parts, a local store might be faster. But for a full rebuild, MAC's kit pricing is competitive.

Final Recommendation

For a restoration looking for authenticity and ease, MAC's 1964 Comet suspension parts are a solid choice. Their front end kit with rubber bushings and standard springs will bring your Comet back to a factory-like ride. If you plan to upgrade handling, consider ordering the polyurethane bushings and a heavier front sway bar (MAC's carries a 1-inch bar for the Comet). Always verify part numbers with your car's original equipment—especially if your Comet has unusual options like a heavy-duty suspension package. With careful installation and proper alignment, your Comet will handle safely and drive the way it did in 1964.
