Body Mount Set

What Is a Body Mount Set?

Body mounts are the critical connection points between a vehicle's body and its frame. Body mount sets include all the bushings, sleeves, and hardware needed to cushion and secure that junction. As the Energy Suspension team explains, body mounts include rubber (or polyurethane) bushings to cushion the body against the noise and vibration of driving — but over time, heat, road grime, UV exposure, and heavy loads cause those original bushings to deteriorate.

When body mounts fail, the consequences are more than cosmetic. Worn or crushed mounts can produce noticeable body sag, allow unwanted body roll, and in some cases cause doors or hoods to misalign and fail to latch properly. Left unaddressed, a compromised mount can literally fall off, leaving the body without a secure connection to the frame.

Why Upgrade to Polyurethane?

Original equipment body mounts use soft rubber — effective at absorbing vibration when new, but prone to cracking, distorting, and crushing under sustained stress. At the other extreme, solid aluminum mounts are too rigid for street use and can transfer harsh loads to surrounding components. Polyurethane body mounts hit the sweet spot between these two options: soft enough for a smooth ride, yet rugged enough for the most demanding road or track conditions.

Polyurethane resists road grime, oil, UV rays, and weather — the very factors that degrade rubber. It also deflects far less under load, helping maintain body-to-frame alignment even during hard driving or when carrying heavy cargo. Most quality polyurethane sets include zinc-plated steel sleeves or rings molded in for added structural integrity at the bolt points.

Choosing the Right Body Mount Set

When shopping for body mount sets, keep these factors in mind:

• Vehicle fitment: Body mounts are highly application-specific. Always verify the set is engineered for your exact year, make, and model.
• Material: Polyurethane offers superior longevity and alignment retention versus OE rubber. Some drivers sensitive to NVH (noise, vibration, harshness) may prefer softer durometer options.
• Hardware inclusion: Look for sets that include all necessary washers, sleeves, and bolts so installation is straightforward.
• Color vs. durometer: Many brands offer red and black versions — these are typically the same durometer hardness, with black versions sometimes containing graphite for self-lubrication to reduce squeaking.
• Warranty: Leading manufacturers back their polyurethane body mounts with substantial warranties, a strong indicator of material confidence.

Top Body Mount Set Brands

Energy Suspension is the most widely specified brand in this category, and for good reason. Their patented Hyper-Flex™ polyurethane formulation is engineered specifically for body-to-frame applications — balancing vibration absorption with the rigidity needed to prevent body sag and maintain alignment. Sets typically include zinc-plated steel rings molded into the bushings for added durability.

Prothane is another top-tier polyurethane specialist with an extensive catalog of vehicle-specific body mount sets. Made in the USA, Prothane's sets are known for outperforming even new OE rubber bushings in both rigidity and longevity — a popular choice for off-road enthusiasts and high-mileage truck owners alike.

NOLATHANE brings its well-regarded suspension bushing expertise to the body mount category, offering precision-engineered polyurethane solutions known for consistent performance in harsh conditions — a solid option for import and domestic truck applications.

Whiteline Suspension rounds out the category with a focused selection of body mount sets that reflect the brand's performance-suspension heritage, particularly popular with enthusiasts looking for precise, long-lasting body control on sport trucks and performance vehicles.
