Hasport Engine Mount Kit for 22+ Civic Si, Sport, and 23+ Integra
If you're tired of your 11th gen Civic or 5th gen Integra rocking the engine around every time you get on the throttle or grab a gear, this is the fix. The Hasport DE4STK kit replaces all three factory mounts (left, right, and rear) with Hasport's billet and steel mounts to keep the L15B7 1.5T planted. Less engine movement means cleaner power delivery, sharper throttle response, and shifts that don't feel like the whole drivetrain is shifting with them.
This is the full kit, and it fits the 2022+ Civic Si and Sport and the 2023+ Acura Integra running the manual transmission. It does not fit the Integra Type S (DE5) or Civic Type R (FL5), those use different mounts. Hasport builds these with robotically welded, laser-cut steel brackets and their own no-tear bushing formula, which is why they hold up where the soft factory mounts tear and sag.
Pick your bushing stiffness
The kit comes in four urethane durometers so you can match how the car feels to how you actually drive it. Stiffer holds the engine tighter but sends more vibration into the chassis, that's the trade-off, so be honest about your use.
| 62A | Street. Closest to stock feel, keeps vibration low while still a big upgrade over worn rubber. |
| 70A | Street with occasional track. More rigidity without making the daily commute miserable. |
| 88A | Dedicated track. Stiff, sharp drivetrain feel, expect noticeably more vibration. |
| 94A | The stiffest Hasport makes. Full track use, maximum engine control, most NVH. |
For most people daily-driving a Si or Integra, stay with 62A or 70A. The 88A and 94A put real strain on the rest of the car and aren't worth the harshness on a street build.
Want stock comfort? Just do the rear
If you mostly want to kill the engine slop without committing to full-kit harshness, you don't have to run all three. Replacing only the rear mount controls the majority of the engine movement (it's the one doing the most work under acceleration and braking) with way less added vibration than the full kit. It also takes load off your factory left and right mounts so they last longer. A lot of street drivers go rear-only first and are happy there.
