Fabtech K2302DL – 17–21 Ford F250/F350 4WD Diesel 8" 4-Link System w/ Dirt Logic 4.0 Coilovers & 2.25 Rear Shocks

The ultimate suspension upgrade for Ford Super Duty owners who demand maximum performance on and off the road.

The Fabtech K2302DL 8" 4-Link System is engineered to transform your 2017–2021 Ford F250 or F350 Diesel 4WD into a powerhouse of strength, articulation, and control. By replacing the factory radius arm setup with a true 4-Link suspension, this system delivers less caster change on-road for improved stability and increased articulation off-road for tackling rugged terrain.

At the heart of this system are the massive Dirt Logic 4.0 Remote Reservoir Coilovers, providing industry-leading damping and fade-free performance. Paired with Dirt Logic 2.25 rear shocks, the ride is smooth, controlled, and built to handle both highway cruising and aggressive trail runs.

Exclusive to this kit is Fabtech’s extended-length Track Bar system, specifically designed for late-model Super Duty trucks with sensitive steering boxes. This proprietary design reduces steering push, maintains proper draglink geometry, and allows full lock steering with 15.50” wide tires and 4-3/4" BS wheels.


Key Features

  • 8" Lift Height – Clears up to 40” tires for a commanding stance and superior off-road capability.

  • 4-Link Conversion – Replaces factory radius arms with heavy-duty links for improved geometry, articulation, and durability.

  • Fabtech Extended Track Bar – Exclusive 4” longer offset design w/ 1/4" steel bracket improves steering control and reduces push.

  • Dirt Logic 4.0 Coilovers (Front) – Massive 4” diameter stainless steel shocks with aluminum reservoirs for unmatched damping.

  • Dirt Logic 2.25 Shocks (Rear) – Tuned to balance strength and ride quality under load and aggressive terrain.

  • Bolt-On Installation – No cutting or welding required; engineered for proper fit and reliability.

  • Proven Durability – Over a decade of real-world testing in commercial and military applications.

  • 5-Year / 60,000 Mile Powertrain Warranty – Industry-leading coverage for peace of mind.

Why Choose the Fabtech K2302DL?

This is Fabtech’s premier 8-inch 4-Link system, designed for truck owners who want maximum suspension performance, steering stability, and rugged durability. The combination of race-quality Dirt Logic 4.0 coilovers and Fabtech’s proven 4-Link geometry makes it the pinnacle suspension solution for Ford Super Duty Diesel trucks. Whether hauling heavy loads, tackling extreme trails, or cruising the highway, the K2302DL delivers strength, control, and confidence that stock systems can’t match.
