1. Innovative Mounts Street Motor Mount: Best Overall
Innovative Mounts are widely recognized in the performance community for their solid billet aluminum construction. In our evaluation of owner feedback, we found that the 85A durometer polyurethane offers an excellent balance between reducing engine hop and maintaining street drivability. The materials used are specifically designed to withstand high horsepower applications where stock rubber mounts would fail.
However, based on our research, these mounts are not ideal for those prioritizing a luxury ride quality. The stiffer polyurethane naturally transmits more engine noise and vibration to the chassis. We recommend skipping this option if you are sensitive to cabin noise or if your vehicle is strictly a daily commuter used in stop and go traffic.
- Billet aluminum construction for high strength
- Street density polyurethane for reduced engine movement
- Energy suspension bushings included for longevity
Pros: Significantly improves throttle response and shifting; Highly durable materials resist oil and road degradation
Cons: Transmits more vibration into the cabin than stock rubber mounts
2. Energy Suspension Hyper-Flex Master Kit: Best Polyurethane Upgrade
Energy Suspension offers a adaptable solution for enthusiasts looking to upgrade their entire mounting system. The Hyper-Flex polyurethane material is formulated to be much stronger than OEM rubber, providing improved stability and control. Our comparison of user reports indicates that these bushings effectively eliminate the mushy feeling often associated with worn stock mounts.
It is important to note that this product requires significant mechanical skill to install. The process involves pressing out the old rubber shells and pressing in the new polyurethane bushings. If you do not have access to a hydraulic press or professional installation tools, we suggest looking at complete bolt-on replacement options instead.
- Includes bushings for multiple mount locations
- Resistant to oil and coolant contamination
- Formulated to outlast traditional rubber
Pros: Comprehensive kit solution for full vehicle refresh; Excellent durability against underhood elements
Cons: Installation requires pressing out old bushings which is labor intensive
3. Anchor 2605 Engine Mount: Best OEM Replacement
Anchor provides a reliable solution for drivers looking to restore their vehicle to factory condition. We analyzed the specifications and found that these mounts adhere closely to original equipment dimensions and rubber durometer ratings. This ensures that the ride quality remains soft and quiet, exactly as the manufacturer intended.
While these are excellent for daily driving, they are not designed for performance driving. The rubber is susceptible to wear under high torque or extreme temperature fluctuations. We concluded that this is the correct choice for commuter cars but should be avoided for modified vehicles or track use where increased rigidity is required.
- Manufactured to meet OE specifications
- Direct fit replacement with no modification required
- Rubber formulation dampens vibration effectively
Pros: Restores factory ride quality and comfort; Generally straightforward installation process
Cons: Rubber material may degrade faster than polyurethane in extreme conditions
4. Westar EM-2657 Engine Mount: Best Value Rubber
Westar is a well-known aftermarket brand that offers a balance between affordability and functionality. In our evaluation, we observed that their mounts often feature hydraulic or rubber mechanisms designed to mimic OE performance. The corrosion-resistant coatings on the metal housings are a notable feature that contributes to a longer service life in rust-prone environments.
Despite the value proposition, we found scattered reports regarding minor alignment issues during installation. While most units fit correctly, some owners reported needing to slightly modify bolt holes. If you are looking for a guaranteed perfect fit without any potential for adjustment during installation, you might want to consider a higher-tier OEM supplier.
- Precision fit for specific applications
- Corrosion resistant plating on metal components
- Internal hydraulic fluid for vibration absorption
Pros: Cost effective option for standard repairs; Good isolation of engine vibration
Cons: Some user feedback mentions occasional fitment tolerance issues
5. DEA A4604 Motor Mount: Reliable Standard
DEA motor mounts serve as a standard replacement option for a variety of vehicles. Our research indicates that they utilize standard rubber compounds and stamped steel constructions similar to factory parts. They are a viable choice when the primary goal is to fix a broken mount without altering the vehicle’s driving characteristics.
However, these mounts do not offer any upgrade in terms of performance or longevity over the stock parts they replace. Based on owner feedback, they tend to have a standard lifespan comparable to OEM parts. We suggest skipping this brand if you are looking for a permanent upgrade that will outlast the original factory component.
- Validated quality control processes
- Stamped steel housing for structural integrity
- Engineered to match original rubber hardness
Pros: Adequate replacement for standard maintenance needs; Competitively priced for budget repairs
Cons: Not as rigid or durable as performance aftermarket options
6. Schmidt 8174 Motor Mount: Budget Option
Schmidt offers motor mounts that cater to the budget-conscious consumer. In our comparison of lower-cost options, we found that these mounts provide the basic function of holding the engine in place. They are often selected for older vehicles where the investment in premium parts is not economically justified.
We did find evidence in user reviews suggesting inconsistency in rubber hardness and overall build quality. Some owners reported premature cracking or sagging sooner than expected. If you are repairing a vehicle you plan to keep for a long time, we recommend investing in a more durable brand to avoid repeating the labor of replacement.
- Economic repair solution for older vehicles
- Basic rubber dampening technology
- Lightweight design
Pros: Very accessible price point for urgent repairs; Fits specific chassis applications correctly
Cons: Quality control consistency varies between batches

Frequently Asked Questions
How do I know if my motor mounts are bad?
Common signs include a clunking noise when accelerating or shifting, excessive vibration felt in the cabin, and visible engine movement when the hood is open. We researched owner reports and found that these symptoms usually indicate the rubber has failed or the fluid in hydraulic mounts has leaked.
What is the difference between rubber and polyurethane mounts?
Rubber mounts offer softer dampening for a quieter ride, whereas polyurethane mounts are stiffer and more durable. In our evaluation, polyurethane significantly reduces engine movement for better performance but transmits more vibration to the chassis compared to the OEM-style rubber.
Do aftermarket motor mounts affect warranty?
Generally, installing aftermarket parts does not void your entire vehicle warranty. However, if the aftermarket part causes damage to a related component, that specific repair might not be covered. We compared warranty policies and suggest checking your specific vehicle warranty terms before modifying powertrain components.
Can I replace motor mounts myself?
Replacing motor mounts is a labor-intensive process that often requires supporting the engine weight with a jack or hoist. Based on the complexity we evaluated, this task is suitable for experienced DIY mechanics but may be difficult for beginners due to the need for specific tools and safety precautions.
How long do aftermarket motor mounts last?
Lifespan varies by material and driving conditions. OEM-style rubber mounts typically last 60,000 to 100,000 miles. Our research indicates that polyurethane mounts can often last the life of the vehicle, while budget rubber options may fail sooner depending on driving habits and exposure to elements.
Our Verdict
After extensive research and comparison, the Innovative Mounts Street Motor Mount stands out as the top pick for performance enthusiasts seeking durability and reduced engine movement. For those needing a reliable OEM-style replacement that maintains stock comfort, the Anchor 2605 is our runner up choice.
