 5 Ways to Modernize Your Classic Car Suspension

 How can I Improve the drivability and performance of my classic car?

Classic cars and trucks from the 50’s, 60’s and 70’s had design, styling and engines that we still reference and use today in modern production vehicles. In the past, when it came to suspension upgrades, performance options were limited. With modern technology and with decades in suspension engineering improvements, we list our top 5 ways to modernize and improve your classic car suspension.

Keep it Original?

If you’re doing a Concourse level restoration on a vintage 1968 Shelby Mustang GT500 KR, you’re probably going to want to run as many OEM (Original Equipment Manufacturer) or NOS (New Old Stock) parts as possible. But why run all original parts? There are many reasons, but in this case, the you may want to get the car to a 100-point level build for being completely original. This is important at an event like the Concourse d’Elegance. Keeping the integrity of the car without modification may also increase a car like this’ value as so few were produced and still exist today.

This is one extreme example, but for most classic car owners, they want to be able to drive their classic and have a level of comfort and safety while keeping the integrity of their classic car or truck.


There are many companies that specialize in high quality, aftermarket replacement bushings.
Aftermarket bushing replacements are typically one of the best suspension improvements you can make on an older vehicle as many times the bushings and rubber body mounts are the first things to wear out over time.

Aftermarket companies are typically running smaller production runs of parts and a components which usually typically delivers a higher quality product that’s had more attention to detail when compared to a mass produced part where an overseas company made millions of said part with lesser quality compounds and materials used.

If you have an older vehicle, definitely check body mounts and suspension bushings for wear as replacing these is and will be one of the best things you do for your ride.

 Update Shocks & Springs

Once you’ve updated your body and suspension bushings on your classic, check out the shocks and springs.
Stock Mustang Shocks
Many classic cars use a basic gas shocks or struts, coil-springs and sometimes a leaf spring in the rear.

To achieve a modern day ride quality with your classic, we recommend updating your shocks and springs. You can run a lowered spring if you’re looking to change your stance or ride-height. You can also run adjustable shocks, which offer more tuning capabilities for a ride quality you can tune per your handling preference.

If you’re looking for suspension upgrades that can raise, lower and offer an even wider range of adjustability – A coilover shock may be exactly what your classic car or truck needs. Coilover shocks combine a shock and performance spring that allows lowering with fine tune shock adjustments for an improved center of gravity, stance and modern day handling.

New Sway Bars

Just about every car or truck comes with some kind of sway bar or anti roll bar. Many of the OEM style sway bars are mass-produced. In mass production, less material may be used, lesser grades of steel can be used and sway bars may be solid or tubular that both have their pros and con’s depending on the application.

Replacing OEM sway bars with a high quality sway bar like those found at Performance Online or H&R springs can improve cornering ability and chassis anti-roll extremely well.

High quality tubular sway bars are designed to use adjustable end links. With adjustable end links, you can set your sway bar in different positions to further control body roll. Stiffer sway bars setup properly can prevent unwanted body-roll. Reducing side roll helps keep suspensions and tires planted for improved handling under hard cornering.
Upgrading your sway bars is a great way to improve the ride quality and handling of your vehicle.

Tubular Control Arms

If you’re looking to replace decades old control arms, going with a tubular control arm setup is a great way to go.
