Gertrdti FR250SDJ Rear Bump Stop Rubber Kit for Ford F-250 Super Duty (2017–2025) — Pair, Progressive Closed-Cell Support

Designed specifically for Ford F-250 Super Duty models from 2017 through 2025, the Gertrdti FR250SDJ rear bump stop rubber kit is a direct-fit aftermarket solution engineered to mimic OEM dimensions while delivering progressive support as loads increase. Sold as a left-and-right pair for both 2WD and 4WD trucks, these closed micro-cellular rubber springs improve rear-end stance and stability without requiring air systems, special tools, or extensive modification.

How does the FR250SDJ improve towing and hauling performance?

The FR250SDJ adds progressive spring support that engages more as payload increases, reducing rear sag and helping the truck maintain a level attitude under load. That leads to improved trailer alignment, steadier braking, and less body roll when cornering with heavy cargo.

• Progressive closed-cell rubber design that increases stiffness with compression
• Rated capacity engineered to support heavier rear loads and reduce squat
• Helps maintain factory ride height for safer towing geometry

Are these bump stops easy to install for a DIYer?

Yes—installation is straightforward and compatible with the stock mounting locations, so no custom fabrication or air lines are required. Typical installs can be completed quickly with common hand tools and basic mechanical experience.

• Direct-fit for 2017–2025 Ford F-250 Super Duty, 2WD and 4WD
• Sold as a pair (left and right) to replace both rear springs simultaneously
• No compressors, hoses, or ongoing maintenance needed after installation

What ride and handling changes should I expect on-road?

On empty or lightly loaded runs you’ll notice a smoother, more controlled rear-end feel with less abrupt bottoming. As load increases the FR250SDJ progressively firms the rear suspension which reduces sway, roll, and squat, improving driver confidence.

• Better damping through closed-cell rubber that absorbs shocks
• Reduced body roll and sway when cornering or in crosswinds
• Consistent performance whether the truck is unloaded or fully loaded

Will these match the OEM fit and durability expectations?

Gertrdti designed the FR250SDJ to replicate OEM geometry and key dimensions so they mount cleanly into stock locations. The micro-cellular rubber construction resists compression set better than some cheaper materials, giving long-term service without complex upkeep.

• Engineered to OEM dimensions for a precise retrofit fit
• Durable closed-cell rubber resists permanent deformation
• Backed by Gertrdti aftermarket support for parts and installation help

Who is this for? The Gertrdti FR250SDJ rear bump stop rubber kit is aimed at F-250 owners who regularly carry heavy loads, tow trailers, or want to restore factory stance and handling without installing air bags or complex leveling systems. It’s also suitable for fleet operators and DIY mechanics seeking a reliable, low-maintenance upgrade that installs quickly and improves stability under varying loads.
