Hasport CL9J J Series Engine Swap Mounts for 04-08 TSX

Hasport CL9J J Series Engine Swap Mounts - 2004-2008 Acura TSX

Swapping a J35 or J37 V6 into your CL9 TSX and you need engine mounts that actually bolt in without custom fabrication? The Hasport CL9J mount kit lets you swap any J series V6 (J30, J32, J35, J37) into your 2004-2008 TSX using your stock subframe. No cutting, no welding, no custom brackets. You're bolting the Hasport mounts to your factory subframe and dropping the J series motor in. This is how you swap a V6 into a TSX without spending weeks fabricating mounts. Hasport's done the engineering work already so you don't have to.

Here's What Makes This Kit Different

Most engine swap mount kits require cutting your subframe, welding custom brackets, or dealing with terrible axle angles and ground clearance issues. Hasport designed this kit in CAD to optimize engine placement for proper axle geometry and ground clearance. The engine sits where it needs to be for your axles to work right and for your oil pan to not drag on speed bumps. The mounts bolt to your stock subframe mounting points. You're not modifying your subframe. If you want to swap back to a K series later, you can unbolt the Hasport mounts and bolt your factory K series mounts back in. The kit's reversible.

Three Bushing Durometer Options

Hasport offers three different bushing durometers (stiffness levels) so you can match the mounts to how you're using your car. Higher durometer numbers mean stiffer bushings, which reduce engine movement but transmit more vibration into the cabin.

62A Durometer (Street): Softest option. Feels closest to stock. These bushings isolate engine vibration really well so you're not feeling every engine vibration in your seat. The motor moves a bit more under hard acceleration or shifting, but that's the trade-off for comfort. If you're daily driving your swapped TSX and you want it to feel civilized, get 62A. You'll barely notice the mounts are there.

70A Durometer (Street/Track): Middle ground between comfort and performance. You'll feel more engine vibration than 62A but the motor moves way less under hard throttle or gear changes. Good for cars that see occasional track days but still get driven on the street regularly. Most people running street/track builds go with 70A. It's stiff enough to control the motor on track but not so harsh that daily driving sucks.

88A Durometer (Track/Street): Stiffest option. The motor barely moves under load but you're feeling way more vibration through the chassis, steering wheel, and shifter. Your interior's gonna vibrate at idle and the whole car buzzes more at low RPM. On track, the engine stays planted and you get better throttle response because the motor's not rocking around. For dedicated track cars that occasionally see street use, 88A works. For daily drivers, it's too harsh unless you don't care about comfort.

CNC-Machined Billet Aluminum

The mount brackets are CNC-machined from billet aluminum. They're not stamped steel or welded together from multiple pieces. Hasport machines them from solid aluminum blocks for strength and clean fitment. The mounts are designed to handle the torque and weight of a J series V6 without flexing or breaking. Hasport backs the kit with a lifetime warranty, which means they're confident the mounts won't fail.

Note: Choose your bushing durometer when ordering. 62A is best for daily drivers who want comfort. 70A is the most popular choice for street/track cars - it's the sweet spot between vibration control and performance. 88A is for track-focused cars that occasionally see street use. If you're daily driving the car, don't get 88A unless you're fine with constant vibration. The Hasport mounts are just the engine mount portion of the swap. You'll also need J series axles, wiring, ECU, fuel system, exhaust, cooling system, and all the other swap components. This mount kit works with J series manual or automatic transmissions.
