PRL Rear Motor Mount Upgrade for 2016-2021 Honda Civic

PRL Motorsports Rear Motor Mount - 2016-2021 Honda Civic

Sick of getting rattled to death by aftermarket motor mounts? PRL makes a rear motor mount that actually reduces engine movement without turning your Civic into a vibrating mess. It uses 60A EPDM bushings instead of urethane, which means it's stiffer than the factory mount but way quieter than urethane mounts. The mount's machined from billet 6061 aluminum with an I-beam design that resists bending without adding a ton of weight. If you want to reduce wheel hop and improve throttle response without rattling your fillings loose, this is the mount you need.

Why Most Aftermarket Mounts Rattle Like Crazy

Here's the problem with most aftermarket motor mounts: they use urethane bushings in a basic bracket design. Urethane's stiff, which reduces engine movement, but it transmits way more vibration into the chassis than rubber. That's why your car rattles and buzzes after you install urethane mounts. PRL uses EPDM bushings instead of urethane. EPDM's denser than urethane, which means PRL can use a softer 60A durometer and still get more rigidity than the factory mount. The softer durometer absorbs vibration way better than hard urethane, so you get the performance benefits without the constant rattling.

EPDM Doesn't Break Down Like Urethane

Urethane bushings mushroom and wallow out over time, especially when they're exposed to heat, oil, and road chemicals. EPDM resists heat, ozone, chemicals, and abrasion way better than urethane. It doesn't break down or deform over time. That's why OEM manufacturers use EPDM in factory mounts. PRL's EPDM bushings are press-fit into the aluminum mount body, which eliminates any gaps that would let metal-on-metal contact happen. The bushings absorb engine vibration instead of transmitting it into the chassis.

I-Beam Design Resists Bending

PRL designed this mount with an I-beam cross-section, which is the same design used in connecting rods and structural beams. I-beams resist bending, stress, and vibration way better than flat plates or simple brackets. PRL was able to add way more material than the factory mount without making it crazy heavy. The extra material increases rigidity and strength, which reduces engine movement during hard acceleration and shifting.

One Mount for All Applications

PRL tested this mount on different Civics with different engines and transmissions (1.5T CVT, 1.5T manual, Si, Type R) to find one bushing durometer that works for everyone. You're not picking between street and track versions or soft and stiff options. PRL settled on 60A EPDM because it works for stock daily drivers and modified track cars without being too soft or too stiff for either.

What You Get

• PRL Motorsports rear motor mount
• CNC-machined billet 6061 aluminum construction
• I-beam design for maximum rigidity
• Two press-fit 60A EPDM bushings
• Zinc-coated bushing shells and center inserts
• All mounting hardware included

Fits Your Car

• 2016-2021 Honda Civic Sport
• 2016-2021 Honda Civic LX
• 2016-2021 Honda Civic Si
• 2017-2021 Honda Civic Type R FK8

Compatible Engines

• L15B7
• K20C1

Note: Fits both manual and CVT transmissions. This is a single rear motor mount. It replaces the factory rear mount only. If you want to do all your mounts, you'll need to order front and side mounts separately. The 60A EPDM bushings are softer than most urethane mounts but stiffer than the factory mount. You'll feel slightly more vibration than stock, but way less than urethane mounts. There's no break-in period. The mount works right away.
