SUSUPACI Ford Mustang Jounce Bumper Kit — 4-Piece Front & Rear (2005–2014) Yellow OE Replacement

SUSUPACi M5570A is a 4-piece front and rear jounce bumper kit designed to replace OE M-5570-A bump stops on 2005–2014 Mustangs and Shelby GT500 models to protect suspension components and improve ride comfort.

This SUSUPACi kit contains two rear and two front bump stops plus four screws, matching OE part numbers M5570A / M-5570-A. Constructed from durable rubber bonded to a metal plate and finished in high-visibility yellow, these bumpers cushion extreme suspension travel, reduce vibration and noise transfer into the cabin, and restore the original stop points for Mustangs equipped with the referenced factory parts.

How do these bump stops protect my Mustang's suspension?

When the suspension reaches its travel limit, the jounce bumpers absorb and distribute impact energy so metal components do not collide directly. The rubber face compresses while the metal backing plate anchors the part, preventing damage to struts, mounts and control arms during hard compression events.

• Direct OE replacement for M5570A / M-5570-A fitment
• Rubber reduces shock and prevents metal-to-metal contact
• Metal plate ensures secure mount and correct stop position
• Four screws included for straightforward hardware replacement

Will these bumpers improve ride quality and reduce noise?

Yes — by providing a softer contact surface at full compression, the bumpers limit vibration transfer into the chassis and lower the sharp clunks that occur when suspension bottoms out. Drivers will notice a calmer feel at the limit of suspension travel and reduced interior noise from hard impacts.

• Compressible rubber reduces harsh rebound and thud noises
• Helps maintain consistent suspension damping behavior
• Improves passenger comfort during firm bumps or track use

Are these bumpers durable and weather resistant?

SUSUPACi uses wear-resistant rubber combined with a corrosion-resistant metal plate to withstand road grime, heat cycles and exposure to moisture. The materials are formulated to resist aging and cracking so the bumpers keep their elasticity and protective function over long service intervals.

• High-quality rubber resists abrasion and UV-related aging
• Metal backing offers structural strength and corrosion protection
• Yellow finish aids visual inspection during maintenance

How difficult is installation and what’s included?

Installation is designed to be a direct replacement for the original bumpers. Removing the old mounting plate can require leverage or a chisel, but once cleared the SUSUPACi units slide into place and fasten with the supplied screws for a secure fit.

• Kit includes: 2 rear bumpers, 2 front bumpers and 4 screws
• Basic hand tools recommended; pry tool may be needed to remove old pieces
• Fits 2005–2014 Mustang V6/GT, 2007–2011 Shelby GT500, and factory 2012–2014 Shelby GT500
