SUSUPACI jounce bumper kit for Ford Mustang — 4-piece Yellow front & rear direct-fit, OE-replace

The SUSUPACi M5570A jounce bumper kit is a 4-piece front and rear suspension stop set designed to replace M-5570-A and protect and soften suspension impacts on 2005–2014 Ford Mustangs.

If your Mustang is producing harsh clunks at full suspension travel or you want to restore original ride damping and component protection, this kit provides direct-fit rubber bumpers with metal mounting plates for V6, GT and Shelby applications. The set includes two rear and two front jounce bumpers plus four mounting screws and matches OE reference M5570A to simplify replacement.

How does this bumper kit protect my Mustang’s suspension?

These jounce bumpers absorb and spread impact energy when the suspension bottoms out, preventing hard contact between suspension parts and the chassis. The combined rubber-and-metal construction reduces stress on control arms, shocks and mounting points.

• High-density rubber cushions impact and resists wear and aging.
• Metal backing plate ensures secure mounting and load distribution.
• Designed to match OE load geometry for correct energy transfer.

Will installing these bumpers make the ride more comfortable?

Yes — replacing worn jounce bumpers minimizes harsh bangs and vibration transmitted into the cabin at full compression. The kit reduces noise from suspension-to-body contact and helps maintain smoother body control over rough surfaces.

• Rubber material dampens high-frequency shocks and vibration.
• Stops abrupt suspension travel that creates noise and jolts.
• Restores intended bump-stop travel for predictable handling.

Are these parts durable and weather resistant?

The bumpers combine weather-resistant rubber with a corrosion-resistant metal plate to withstand road debris, salt and UV exposure. Their construction emphasizes longevity so you don’t replace them frequently under normal driving conditions.

• Rubber compound engineered for anti-aging and abrasion resistance.
• Metal plate prevents deformation and spreads load across the mount.
• Yellow finish improves visibility during inspection and service.

How straightforward is the installation for a home mechanic?

These jounce bumpers are direct replacements for OE M5570A units and can be installed with common hand tools. Removing the original mounting plate may require leverage, but the new bumpers slide into place and fasten with the included screws.

• Direct-fit design for 2005–2014 Mustang V6, GT and 2007–2011 Shelby GT500.
• Includes 4 screws for immediate installation.
• Simple pry-out of old bumper and press-in of new unit; closed-end wrench helps seat it fully.

Who is this for: This SUSUPACi M5570A 4-piece jounce bumper kit suits Mustang owners who want to restore OEM bump-stop performance or replace worn suspension components without modifying the chassis. It’s a practical upgrade for daily-driven V6 and GT models, track-prepped cars seeking reliable suspension limits, and Shelby owners who need direct-fit replacements for 2012–2014 GT500 original equipment.
