Hasport CL9STK Engine Mount Set - 04-08 Acura TSX & 03-07 Honda Accord
Billet aluminum mounts that replace the front, left, right, and rear positions on a manual transmission TSX or Accord. Beyond looking considerably better than the factory rubber, they stop the K24 rocking around under load, which is what cleans up your shifts and keeps the drivetrain from absorbing power that should be going to the road. Four bushing durometers, so you can match how you actually drive.
Read This First: You Need A Block Bracket
Important before you order, because this kit alone won't get the engine in.
You'll need either a CR-V post mount or the Hasport Universal K-Series Block Bracket (UKBB). The bracket is what the mount attaches to on the engine side, and without one you'll have mounts and nowhere to bolt them.
We stock both, so grab whichever suits your build in the same order rather than discovering the gap with the engine on a hoist.
The Low Profile Rear Mount
Worth calling out, because it's a genuine design decision rather than a spec. Hasport built the rear mount with a low profile specifically to open up room for turbo applications.
If you've got a turbo K24 or you're planning one, that clearance matters. Downpipe routing and turbo positioning in that area is tight enough that a conventional rear mount becomes something you're working around. This one gives you space you'd otherwise be fabricating for.
Manual Transmission Only
Two things to confirm.
This kit is built around the stock 7th gen Accord and 1st gen TSX manual transmission. If you're running a different gearbox, this isn't the right set.
Your chassis can start life as an automatic though. If you're doing an auto-to-manual conversion, these work fine, and Hasport makes the CL9TCB mount brace which includes the pattern for adding a manual pedal assembly. That's the piece that makes an auto-to-manual conversion straightforward rather than a fabrication project.
It Won't Work With The Stock Airbox
Worth knowing before install day. This mount kit is not compatible with the factory TSX or Accord airbox, so plan on an intake as part of the same project.
Pick Your Durometer Honestly
Four options covering everything from a daily driver to an eight-second drag car. The right one depends on how you use the car rather than what sounds most serious.
62A (street) is the livable choice. It locates the drivetrain far better than twenty-year-old factory rubber while keeping vibration minimal. If the car is a daily, start here.
70A (race) is the middle ground for a car that gets driven hard but still sees road duty. Noticeably tighter, still tolerable at idle.
88A (extreme race) and 94A (most extreme race) lock everything down for maximum control. Excellent for a track or drag car, genuinely buzzy in traffic, especially with a lightweight flywheel.
Be honest with yourself. Almost everyone wants the stiffest option until they've commuted on it for a week, and even 62A transforms how the car feels compared to worn factory mounts.
Why Mounts Matter
Mounts are the reference points for your entire drivetrain. When they're soft or worn, the engine moves under load, and everything connected to it moves too. Your shifter moves relative to the transmission, which is why shifts go vague. Your axles change angle. Your exhaust swings toward whatever's nearby.
Lock it down and all of that stops. It's not a horsepower modification, it's the one that makes the horsepower you have arrive at the wheels instead of getting absorbed by the car flexing around it.
Built To Last
Hasport designs these with CAD/CAM software and machines them from billet aluminum, and they carry a lifetime warranty. That warranty tells you what they expect from them, which on a part living under an engine in road salt and heat is worth something.
Fitment
2004-2008 Acura TSX
2003-2007 Honda Accord (K24)
Manual transmission. Works on an automatic chassis if you're converting to manual.
Who Should Run These
This is for the TSX or Accord owner whose factory mounts have gone soft after two decades, the builder adding power who needs the drivetrain to stay put, or anyone doing an auto-to-manual conversion who's putting the drivetrain in properly. Sort your block bracket, pick a durometer that matches your commute, and get the engine located where it should be.
