Hasport BB6STK Replacement Engine Mounts for 97-01 Prelude

Hasport Performance Engine Mount Kit - 1997-2001 Honda Prelude (H Series)

Your 5th gen Prelude's got stock rubber engine mounts that are 25+ years old and they're torn, oil-soaked, or just too soft to control the engine anymore. You're on the throttle and the engine's rocking. You're shifting and the drivetrain's moving around. The stock mounts let the H series engine pitch and twist under load which shows up as sloppy throttle response, wheel hop, and missed shifts. Hasport's BB6STK mount kit replaces all four stock mounts with billet aluminum brackets and urethane bushings that lock the engine down. You're getting sharper throttle response, cleaner shifts, and better traction because the engine's staying where it's supposed to be instead of flopping around. The kit's available in four durometers. 62A for street use. 70A for street cars that see occasional track days. 88A and 94A for dedicated track cars. Pick the stiffness that matches how you're using the car. Stiffer mounts control the engine better but they transfer more vibration into the cabin. This is what you install when you're done with sloppy engine movement and you're ready for a mount setup that actually works.

Here's Why Stock Rubber Mounts Feel So Sloppy

The stock Prelude mounts use rubber bushings that are designed for comfort and vibration isolation. Honda didn't want you to feel any engine vibration. The trade-off's mounts that are too soft to control the engine under load. The rubber compresses. The engine pitches forward when you're on the throttle. It rocks back when you lift. It twists side to side when you're shifting hard. All that movement shows up as delayed throttle response, wheel hop on launch, and sloppy gear engagement. The stock mounts are also 25+ years old at this point. The rubber's cracked. It's oil-soaked. It's deteriorated. Even if they were perfect when new, they're shot now. Hasport's mount kit replaces the soft rubber with urethane bushings that are way stiffer. The billet aluminum brackets are stronger than the stock stamped steel. The engine stops moving. You're getting direct power transfer and the drivetrain feels connected instead of loose.

Four Durometer Options - Pick What Matches Your Use

Hasport offers this mount kit in four durometers. That's the stiffness of the urethane bushings. Lower number means softer bushings and more vibration isolation. Higher number means stiffer bushings and more engine control. Here's how to pick. If you're building a street-driven Prelude and you want mounts that are way better than stock but you don't want to deal with a ton of vibration, go 62A. That's the street option. It's still way stiffer than the torn 25-year-old stock mounts but it's not going to rattle your teeth. Most people run 62A. If your Prelude sees occasional track days or autocross and you want more engine control than 62A provides, go 70A. That's the race option. Moderate vibration at idle but it smooths out at cruise. If you're building a dedicated track car that doesn't see street duty, 88A or 94A are the stiffest options Hasport makes. Significant vibration. Heavy idle. Your dash will shake. Don't put 88A or 94A in a daily driver. You'll hate it.

Complete Four-Mount Kit - Left, Right, Rear, and Front Torque Mount

The BB6STK kit includes all four engine mounts. Left mount, right mount, rear mount, and front torque mount. You're replacing the entire mount system at once which means you're getting matched stiffness across all four mounts. Some people buy mounts one at a time and end up with different brands or different durometers at each mount point. Now you've got the engine locked down on one side and flopping around on the other. The mounts are fighting each other. Hasport's kit gives you all four mounts in the same durometer. The engine's controlled evenly from all sides. The loads are balanced. The engine moves predictably instead of twisting in weird directions. That's what you want when you're building a car that actually works.

Billet Aluminum Brackets and Lifetime Warranty

Hasport's mount brackets are CNC-machined from billet aluminum. They're stronger than the stock stamped steel brackets. The urethane bushings are Hasport's no-tear formula that's designed to handle the loads without cracking or failing. Everything's designed in CAD/CAM software so the fitment's precise. The mounts bolt to the factory locations. No cutting. No welding. No custom work. Hasport backs this kit with a lifetime warranty against defects in materials or workmanship. If a bracket cracks or a bushing fails, they replace it. That's how confident they are that these mounts aren't going to break.
