Part 3: Every Energy Suspension Product Explained — Which Bushings and Mounts Should You Upgrade First?

Version 1.0.0

One reason Energy Suspension has remained one of the most respected names in performance suspension is the breadth of its product lineup. Rather than specializing in one component, the company offers polyurethane replacements for nearly every suspension and drivetrain mounting point on many popular domestic and import vehicles.

This allows enthusiasts to replace only the bushings they need—or completely rebuild an aging suspension with a Master Bushing Kit.

Whether you’re restoring a 1993 Honda Civic, building a Lexus IS300 drift car, tightening the steering on a Toyota Tacoma, or refreshing a Mazda Miata, understanding what each component actually does is the key to building a suspension that performs as intended.

Master Bushing Kits: The Complete Suspension Refresh

If your vehicle is more than 15 years old, chances are nearly every factory rubber bushing has begun to deteriorate.

Instead of replacing individual bushings one at a time, Master Bushing Kits replace nearly every major suspension bushing throughout the chassis.

Examples include:

These kits typically include bushings for multiple suspension locations, allowing the entire suspension to work together as a system rather than leaving old rubber mixed with new polyurethane.

Benefits

Master kits are especially valuable for:

Control Arm Bushings

Control arms determine the exact position of each wheel during suspension travel.

Their bushings absorb loads created by:

As rubber ages, control arm movement becomes increasingly unpredictable.

The result is:

Products like the Energy Suspension 5.3122G Control Arm Bushing Set replace deteriorated rubber with Hyper-Flex polyurethane.

Why Upgrade?

Benefits include:

Control arm bushings are among the most noticeable upgrades for older performance cars.

Steering Rack Bushings

The steering rack transfers driver input directly to the front wheels.

Factory rubber rack bushings allow a surprising amount of movement under heavy steering loads.

Energy Suspension offers products including:

Replacing worn rack bushings helps eliminate unwanted rack movement.

Performance Improvements

Drivers typically notice:

These upgrades are particularly popular among:

Sway Bar Bushings

Sway bars—or anti-roll bars—connect the left and right suspension to reduce body roll.

The bushings supporting the sway bar play a larger role than many enthusiasts realize.

When rubber bushings soften:

Products such as:

restore proper sway bar function.

Benefits

Because sway bar bushings are relatively inexpensive and easy to install, they’re often one of the best dollar-for-dollar suspension upgrades available.

End Link Bushings & Grommets

The sway bar itself is only part of the equation.

End links transfer suspension movement into the sway bar.

Energy Suspension products like the:

replace worn rubber components that often develop:

Fresh polyurethane restores proper sway bar engagement while reducing unwanted movement.

Rear Trailing Arm Bushings

On many Honda platforms, rear trailing arm bushings become one of the first suspension components to fail.

The:

is especially popular among:

Why They Matter

Trailing arm bushings control:

Replacing worn bushings reduces:

For older Hondas, few suspension upgrades provide a larger improvement.

Leaf Spring & Rear Spring Bushings

Truck owners often overlook leaf spring bushings until they begin hearing clunks from the rear suspension.

Energy Suspension offers several options, including:

These bushings help maintain:

Benefits

These upgrades are ideal for:

Transmission Mounts

Suspension isn’t the only place where polyurethane shines.

The drivetrain also relies on rubber mounts.

Products such as the:

replace worn rubber transmission mounts with polyurethane.

Benefits include:

Performance enthusiasts often combine polyurethane engine mounts with transmission mounts for even greater drivetrain control.

Body Mount Bushings

The body of a truck or body-on-frame SUV is isolated from the frame using body mounts.

Over time, these rubber mounts compress and crack.

Products including:

provide an excellent solution for:

New polyurethane body mounts restore proper body alignment while improving chassis rigidity.

Universal Hyper-Flex Components

Not every suspension project uses vehicle-specific parts.

Energy Suspension also produces universal components for custom fabrication.

Examples include:

Examples from the Hyper-Flex lineup include:

These components are commonly used in:

Choosing the Right Upgrade Path

One of the biggest mistakes enthusiasts make is replacing suspension components randomly.

A smarter approach is to prioritize upgrades based on the vehicle’s symptoms.

If your steering feels loose:

Upgrade:

If the rear suspension feels unstable:

Upgrade:

If the drivetrain moves excessively:

Upgrade:

If you’re rebuilding an older chassis:

Start with a Master Bushing Kit.

Refreshing every major suspension pivot at once provides the greatest improvement in handling consistency while reducing future maintenance.

Why Energy Suspension Covers So Many Platforms

One reason Energy Suspension remains a favorite among enthusiasts is its extensive vehicle coverage. The product line supports everything from Honda Civic, CRX, Civic del Sol, Acura Integra, Mazda Miata, Toyota trucks, Toyota SUVs, Lexus IS, Lexus GS, GM performance vehicles, Smart Fortwo, and numerous universal fabrication projects. That broad catalog makes it possible to use the same proven Hyper-Flex® polyurethane technology across nearly every suspension system on a project vehicle, creating a consistent driving feel and long-term durability.

Coming Up in Part 4

Next, we’ll examine real-world performance gains from polyurethane bushings, including how they affect steering response, suspension geometry, body roll, wheel hop, braking stability, towing performance, autocross lap consistency, track-day handling, off-road articulation, and tire wear. We’ll also compare OEM rubber vs polyurethane vs spherical bearings, helping readers determine which material is best for their driving style and build goals while targeting high-value SEO terms like polyurethane suspension bushings vs rubber, suspension handling upgrades, steering response improvement, wheel hop reduction, and suspension performance tuning.
