Product Details
| Part Number: | DC5STK |
| Brand: | Hasport |
| Position: | Mount Kit |
| Transmission: | Manual |
Upgrade your drivetrain with the Hasport Racing DC5STK Performance Engine Mount Kit, engineered for the 2002–2006 Acura RSX (DC5) and 2002–2005 Honda Civic Si (EP3). Designed as a performance replacement for the factory engine and transmission mounts, the DC5STK helps control excessive drivetrain movement while maintaining the engine's stock placement in the chassis.
Hasport uses advanced CAD/CAM engineering to achieve proper fitment, strength, and durability. The mounts replace the factory left, right, and rear mounting points, creating a firmer connection between the K-Series drivetrain and chassis. Reducing drivetrain movement can improve throttle response, shifting consistency, and overall vehicle feel during aggressive acceleration and cornering.
The standard DC5STK configuration works with RSX and 2002–2011 Civic Si manual transmissions. Hasport also offers multiple polyurethane bushing stiffnesses, allowing the kit to be tailored for anything from a daily-driven street car to a dedicated competition vehicle.

Important Fitment Note:
- DC5STK is intended for manual-transmission 2002–2006 Acura RSX and 2002–2005 Civic Si chassis using an RSX or 2002–2011 Civic Si-style manual transmission. An automatic RSX chassis being converted to manual requires Hasport's corresponding DC5AMC configuration. Element and CR-V FWD/AWD transmissions require a different mount configuration.

Cannot thank k series parts enough. I desperately needed this kit and was dreading waiting the standard 4 to 6 weeks it normally takes to ship out. K series parts got these to me in 2 weeks flat! Such a great product! Came with all necessary hardware. Noticed a huge improvement after installing .

I'm over all pleased with them noticed an increase in torque and horsepower compared to my blown oem ones I also notice a lot more vibrations but I personally don't mind

Not too bad. Solid B tech job. Less shaking on the whole chass than I expected, but viabrates nonetheless. Solved my exhaust hitting my underbody issue. More torque to the wheels. Feels more responsive. Solid 8 out of 10. It did require some manhandling but it'll fit easy money. However, maybe it was just me, but the passenger side mounting plate had fitment issues. 1 out of the 3 holes will not line up correctly. If you know you know. But solid mounts! I'm satisfied for the most part.

Hasport for the win. Perfect replacement mounts, vibrations are pretty much non existent.
