Product Details
| Part Number: | RD4STM |
| Brand: | Hasport |
| Transmission: | Manual |
Upgrade your Honda's drivetrain mounting system with the Hasport Racing RD4STM Performance Engine Mount Kit. Designed for manual-transmission 2002–2006 Honda CR-V and 2003–2006 Honda Element models equipped with the K24A1, this performance mount set replaces the factory left, right, and rear mounts with stronger steel mounts and polyurethane bushings.
Factory rubber mounts are designed primarily for comfort and vibration isolation, but they can soften, sag, or tear with age and hard use. Hasport's polyurethane mounting system reduces excessive engine and transmission movement, creating a firmer connection between the drivetrain and chassis. This can provide a more responsive feel during acceleration, deceleration, and gear changes.
The RD4STM is specifically the manual-transmission version of the RD4STK mount system. Multiple polyurethane bushing stiffness options are available, allowing the mounts to be tailored for anything from a daily-driven street vehicle to a dedicated competition build.

Bushing Options
Depending on the exact SKU selected, Hasport's RD4 mount system is available with different polyurethane stiffness levels:
- 62A – Street: Softest and most street-friendly option
- 70A – Track/Race: Firmer response for aggressive street and performance use
- 88A – Race: Very stiff configuration intended primarily for competition
- 94A – Extreme Race: Maximum drivetrain control for dedicated race applications
Increasing bushing stiffness will also increase noise, vibration, and harshness (NVH) transmitted into the cabin.

The transmission configuration is important when ordering:

The manual and automatic mount sets are different and are not interchangeable.
Important Fitment Note:
- RD4STM is the correct manual-transmission mount set for 2002–2006 Honda CR-V and 2003–2006 Honda Element applications. It should not be used on 2007–2011 Honda Elements; those later models use Hasport's YH1STM manual-transmission mount system instead. Always verify model year, transmission type, and desired polyurethane stiffness before ordering.
