DEATH GRIP TRACK BAR - 2017-2026 Ford Super Duty F-250/F-350 4X4
Part # KRFTB17-2
Supersedes Part # KRFTB17
Most Super Duty owners overlook the track bar—until steering starts to feel loose, alignment won’t stay put, or bump steer becomes an issue. From the factory, the track bar is a weak link in the Super Duty’s front suspension. It controls lateral axle movement and directly affects steering response, alignment stability, and ride quality. When a lift or leveling kit is added, the OEM bar’s limitations become even more obvious. Increased leverage, misaligned geometry, and softer bushings lead to vague steering, premature wear, and, in worst cases, death wobble. That’s where the Kryptonite Death Grip Track Bar changes everything.
Engineered for heavy-duty performance, this bar is forged from 1045 carbon steel, delivering unmatched strength and impact resistance. It features on-truck adjustability via a center turnbuckle with tapered locking jam nuts—allowing precise alignment from 0 to 6 inches of lift without removal. The finish is fully e-coated, offering 360° corrosion protection, inside and out, to withstand harsh environments and road salt without compromising performance.
At the core of the system is the pre-installed Kryptonite Death Grip Ball Joint, built around a massive 2.865” hex housing and a 4140 chromoly stud. This greasable, metal-on-metal design is engineered to eliminate deflection while delivering long-term serviceability and rock-solid steering feel. On the opposite end, an oversized heavy-duty bushing absorbs load and minimizes vibration—especially important under towing, off-road, or high-speed conditions.
Every detail was considered—including clearance for factory crossmembers and most aftermarket diff covers, ensuring compatibility across common suspension setups. Whether you’re running stock geometry, a 6” lift, or anything in between, the Kryptonite Death Grip Track Bar brings true strength, serviceability, and precision to your Super Duty’s front end. Don’t wait for loose steering, uneven tire wear, or a failed OE bar to tell you it’s time—this is the upgrade your truck needs from day one.
