Fitment Note
This kit is designed for automatic transmission models. Manual transmission RSX vehicles use different mount configurations and should verify compatibility before ordering.
What Do Engine Mounts Do?
Engine mounts serve several important functions:
- Support engine weight
- Secure the transmission
- Absorb vibration
- Reduce drivetrain movement
- Improve ride quality
Without healthy mounts, the engine can move excessively under acceleration, braking, and shifting.
Common Signs of Worn RSX Engine Mounts
Most factory RSX mounts are now over 20 years old.
Excessive Vibration at Idle
One of the most common symptoms.
Clunking During Acceleration
Engine movement can create noticeable noises.
Harsh Gear Changes
Transmission movement may affect shifting quality.
Engine Rocking
Visible engine movement when revving the engine.
Increased Cabin Noise
Failed mounts allow more vibration into the chassis.
Many owners mistakenly blame suspension or transmission issues when worn mounts are actually the source of the problem.
Complete 4-Piece Replacement Kit
One of the biggest advantages of this package is that it replaces multiple wear items at once.
Included Mount Positions
- Engine Mounts
- Transmission Mounts
- Supporting Drivetrain Mount Components
Replacing all mounts together helps restore balanced drivetrain support and avoids placing extra stress on older remaining mounts.
Helps Restore Factory Driving Feel
As engine mounts deteriorate, the vehicle often feels less refined.
Fresh mounts can help:
Reduce Vibration
Particularly noticeable at stoplights and idle.
Improve Shift Feel
Less drivetrain movement during gear changes.
Reduce Engine Movement
Helps stabilize the powertrain.
Improve Driving Comfort
Makes the vehicle feel newer and tighter.
Many RSX owners are surprised by how much difference fresh mounts can make.
Built to Meet OEM Specifications
According to the manufacturer, the mounts are designed to meet or exceed original equipment specifications.
Benefits include:
- Factory-style fitment
- OEM-inspired performance
- Direct replacement installation
- Consistent drivetrain support
For daily-driven RSXs, OEM-style mounts often provide the best balance between comfort and reliability.
Anti-Freeze Enhanced Rubber Construction
The manufacturer notes the use of anti-freeze additives within the mount construction.
Potential benefits include:
Improved Cold Weather Durability
Helps reduce cracking in low temperatures.
Extended Service Life
Supports long-term reliability.
Better Material Stability
Designed to maintain flexibility under varying environmental conditions.
While California RSX owners may never notice, drivers in colder climates can benefit from enhanced rubber durability.
Why Engine Mounts Fail
Several factors contribute to mount wear over time.
Age
Rubber naturally deteriorates over the years.
Heat Exposure
Engine bay temperatures accelerate aging.
Oil Contamination
Leaking oil can damage rubber components.
Aggressive Driving
Hard launches and spirited driving place additional stress on mounts.
Most RSXs on the road today have reached the age where mount replacement is often overdue.
Direct Replacement Installation
The kit is designed as a direct replacement solution.
Installation generally involves:
- Supporting the engine
- Removing worn mounts
- Installing new components
- Verifying alignment
Professional installation is recommended for owners without access to proper lifting equipment.

Frequently Asked Questions
Will this fit an RSX Type-S?
No. Type-S models use a manual transmission and require different mount configurations.
Can bad mounts cause vibration?
Absolutely. Excessive vibration at idle is one of the most common signs of mount failure.
Should I replace all mounts at once?
Yes. Replacing the complete set helps ensure balanced drivetrain support and reduces future labor costs.
Can worn mounts affect shifting?
Yes. Excessive engine and transmission movement can negatively impact shift quality.
Final Thoughts
The 4-Piece Engine and Transmission Mount Kit for the 2002-2006 Acura RSX Automatic is one of the best maintenance upgrades for restoring the smooth, refined driving experience these cars delivered when new. By reducing vibration, limiting drivetrain movement, and improving overall comfort, fresh engine mounts can make an aging RSX feel significantly younger.
Because sometimes the reason your RSX feels worn out isn’t the engine—it’s the engine moving around like it’s trying to escape the car.
