Energy Suspension 9.9104R Hyper-Flex Universal Competition Bump Stops Red 2-Pack

Vehicle Fitment

• Universal - compatible with a wide range of cars, trucks, SUVs, and off-road vehicles. Intended for leaf spring assemblies, traction bars, control arms, and other suspension applications where a large competition-style bump stop is required.
• Not designed as a direct OE replacement for a specific vehicle - verify dimensions and mounting clearance against your application before installation.

Fitment Notes

• Large competition race-style design - confirm adequate clearance in your suspension assembly before installing, as this is a larger-format bump stop (4.5 in. H x 4.5 in. L x 2.5 in. W).
• Mounts via a single stud with the included 3/8 in. locking nut - verify stud compatibility with your mount location.
• For applications where space is limited, Energy Suspension offers alternate profiles (bullet-shaped snubbers for control arms, low-profile button head for tight clearance situations).

Features

• Large competition race-style bump stop with a reinforced metal plate welded to the mounting plate and fully molded in - engineered for high-load, high-frequency compression cycles.
• Hyper-Flex performance polyurethane construction outlasts factory rubber stops and maintains its shape and durometer under extreme heat, cold, and chemical exposure.
• Cushions suspension at full compression to prevent bottoming-out and protect chassis components from shock damage.
• Specially designed mechanical interlock secures the stop firmly in position during repeated compression events.
• Wedge profile smooths out compression better than cylindrical stops, reducing the abrupt harshness of suspension contact.
• Vibrant red Hyper-Flex finish is resistant to grease, oil, smog, and road chemicals.

Product Description

The Energy Suspension 9.9104R is a large competition race-style bump stop set engineered for high-performance and off-road suspension systems where factory rubber stops fall short. Built from Energy Suspension's signature Hyper-Flex polyurethane, these stops deliver superior durability, heat resistance, and load capacity compared to OE rubber - and they won't crack, tear, or degrade under repeated compression cycles or exposure to oils and road chemicals. The wedge profile is purpose-designed to smooth out the compression arc and eliminate the jarring harshness that cylindrical stops can produce at full travel, making them well suited for leaf spring assemblies, traction bars, and heavy-duty control arm applications.

Each stop features a large reinforced metal plate welded to the mounting plate and molded directly into the polyurethane, providing a stable, rattle-free base under load. A specially designed mechanical interlock keeps the stop seated firmly without migration. The single stud mount with included 3/8 in. locking nut makes installation straightforward on most universal mounting brackets. Sold as a pair in red. Dimensions are 4.5 in. H x 4.5 in. L x 2.5 in. W - verify clearance in your application before installing.
