Body Mount Set

What Is a Body Mount Set?

On body-on-frame vehicles — trucks, SUVs, and classic cars — the body is not welded directly to the frame. Instead, it sits on a series of body mounts: cushioning bushings that isolate the passenger cabin from the chassis. These mounts absorb road vibration, dampen noise, and allow the body and frame to flex independently without cracking or stressing the sheet metal. Over time, factory rubber body mounts compress, crack, and deteriorate — leading to excessive road noise, body shimmy, and even visible gaps between the body and frame.

Replacing worn body mounts is one of the most impactful — and often overlooked — maintenance tasks on a truck or SUV. A fresh body mount set restores the proper ride height at the body line, tightens up handling feel, and dramatically reduces the cabin drone and clunking sounds that come from collapsed or missing bushings. For off-road builds and lifted vehicles, upgraded polyurethane body mounts also provide a more controlled, predictable platform when the chassis is flexing over rough terrain.

Rubber vs. Polyurethane Body Mounts

Body mount sets are available in two primary materials, each with a distinct performance profile:

• Rubber: The factory standard. Rubber mounts offer maximum noise, vibration, and harshness (NVH) isolation and a compliant ride, but they degrade faster and offer less positional stability.
• Polyurethane: Significantly more durable than rubber, poly mounts resist compression set, oil, and ozone. They transmit slightly more road feel into the cabin but deliver improved body control and a longer service life — making them the preferred choice for performance builds and daily drivers alike.

Top Brands for Body Mount Sets

Energy Suspension is the dominant name in polyurethane body mounts, and for good reason. Their application-specific body mount kits are engineered with precise durometer ratings to balance NVH reduction with long-term durability, and they back their products with a limited lifetime warranty. Energy Suspension covers an exceptionally wide range of domestic trucks, SUVs, and classic muscle cars.

Prothane is another respected polyurethane specialist offering full body mount kits for a broad selection of trucks and off-road vehicles. Prothane mounts are known for their consistent fit and come complete with all necessary hardware, making them a straightforward upgrade over sagging OEM rubber.

PullRite brings its precision-engineering expertise to the body mount segment, offering solutions particularly suited to truck applications where towing and payload demands place additional stress on the body-to-frame interface.

Daystar rounds out the top tier with their line of polyurethane and composite body mounts, which are especially popular in the off-road and 4x4 community. Daystar mounts are often designed to complement lift kit installations, helping maintain proper body alignment after a suspension lift.

What to Consider When Shopping Body Mount Sets

• Application fitment: Body mount configurations vary significantly by year, make, and model. Always verify the kit covers every mount location for your specific vehicle.
• Material choice: Match the material to your use case — rubber for a stock-feel daily driver, polyurethane for performance, towing, or off-road use.
• Complete kit vs. individual mounts: Replacing all mounts at once ensures even support and saves labor time if multiple mounts are already worn.
• Hardware included: Many quality kits include new bolts, sleeves, and washers — check what's in the box before purchasing additional hardware.
