Engine Bushings for 1967 Ford Mustang Shelby GT-350

Nolathane engine bushings control how much your Ford Mustang's engine and transmission move, while still isolating vibration from the cabin. The range includes motor mount bushings, motor mount inserts that fill the voids in factory mounts, complete mount sets, and transmission and torque strut bushings.

When engine or motor mounts wear, the engine rocks under load, and you feel it as clunks, vibration, and wheel hop. Polyurethane engine bushings bring that movement back under control. Each listing shows the type, position, and engine and transmission configuration each part fits.

What Engine and Motor Mounts Do on the Ford Mustang

An engine produces torque, and that torque tries to twist the engine in the opposite direction to the crankshaft. Motor mounts, also called engine mounts, hold the engine in place and resist that twisting force, known as torque reaction. Transmission mounts do the same job for the transmission.

Mounts also isolate vibration. An engine vibrates constantly, and soft mounts absorb much of that before it reaches the frame and cabin.

Getting the balance right matters. Mounts need to be firm enough to stop the engine moving too much, but compliant enough to keep vibration out of the cabin.

Types of Ford Mustang Engine Bushings

Engine bushings come in several forms, depending on your Ford Mustang and the result you want. Each listing shows the type and position.

Motor Mount Inserts

Many factory mounts have voids molded into the rubber to make them softer. Motor mount inserts fill those voids with polyurethane, limiting how far the mount can move without replacing it.

Engine Mount Bushings

These replace the original rubber in the mount with polyurethane. Each engine mount bushing gives firmer, longer-lasting control than the factory part.

Complete Engine and Transmission Mount Sets

Complete sets cover every mount for a given engine and transmission, so the whole driveline is supported consistently.

Transmission Mounts and Torque Strut Bushings

Transmission mounts support the rear of the driveline. Torque struts, used on many front-engine layouts, limit the engine?s rocking motion, and their bushings are a common wear point.

Engine Swap Conversion Mounts

Conversion mounts are designed for engine swap conversions, where a different engine is fitted to a vehicle that wasn?t built for it.

Signs of Worn Motor Mounts on Your Ford Mustang

Worn motor mounts usually show themselves through noise and movement. Watch for:

• A clunk when shifting into drive or reverse, or when getting on and off the throttle
• The engine rocking excessively when revved
• Vibration at idle
• Wheel hop under acceleration
• Driveline shunt, where the drivetrain jerks as load changes
• Cracked or collapsed mounts, or fluid leaking from fluid-filled mounts
• The fan contacting the shroud

Inserts or Full Replacement for Your Ford Mustang

There are two main ways to firm up worn or soft mounts, and each suits a different situation.

Motor mount inserts suit mounts that are still bonded and intact. They?re quick to fit, often without removing the mount, and they limit movement by filling the factory voids. The trade-off is that they depend on the original rubber still being sound.

Full replacement is needed when the rubber has torn or separated from the mount. Replacing the bushing or the whole mount takes more work, but it fixes the mount properly rather than reinforcing a part that has already failed.

Rubber and Polyurethane Engine Bushings for the Ford Mustang

Factory rubber mounts are soft, which keeps vibration out of the cabin. But rubber breaks down from oil and heat in the engine bay, softening, cracking, and eventually separating.

Polyurethane engine bushings give firmer control of engine movement and resist oil and grease, so they last well in the engine bay. Their hardness, or durometer, is selected for each application to balance control with vibration.

The honest trade-off is vibration. Polyurethane passes more engine vibration into the cabin than soft rubber, and that?s most noticeable at idle.

Ford Mustang Performance, Towing and Diesel Use

Firmer engine bushings reduce how much the engine moves under hard launches and heavy towing loads. Less movement means power is delivered more consistently, and wheel hop is reduced on vehicles prone to it.

High-torque diesels put a lot of twisting force through their mounts, which makes them well suited to firmer polyurethane control. The result is a more settled driveline, though at the cost of a little more vibration.

Choosing Engine Bushings for Your Ford Mustang

Matching the right parts depends on your engine and transmission. Each listing shows the details.

Engine and Transmission Configuration

Confirm your engine variant and whether your Ford Mustang has a manual or automatic transmission. Mounts often differ between them.

Mount Position

Check which mount you?re replacing, whether front, rear, upper, or lower.

Insert, Bushing or Complete Set

Choose inserts for sound mounts that need firming up, bushings for worn mounts, or a complete set to cover every position at once.

Fitting Engine and Motor Mount Bushings on Your Ford Mustang

Engine mount work is best handled by a qualified installer. The general process looks like this:

• Support the engine and transmission safely
• Work on one mount at a time unless the listing says otherwise
• Fit the new inserts or bushings
• Tighten all fasteners to specification
• Check clearances to the fan, shroud, exhaust, and hoses
• Check the torque again after the first drive

Limitations and Trade-Offs

Engine bushings control movement well, but they have limits:

• Firmer mounts transmit more vibration and noise into the cabin, most noticeably at idle
• Inserts can?t repair a torn or separated mount
• New mounts won?t fix worn CV joints, U-joints, or transmission problems
• Fitment is specific to the engine and transmission configuration

Compliance and Insurance

Make sure your Ford Mustang meets the inspection requirements of the state where it?s registered, including any rules on engine swaps. Let your insurance company know about any modifications.
