The Fabtech 6-inch radius arm lift kit in brief

A 6 in front lift on a 2023 to 2026 Super Duty diesel is what Fabtech's K2413 radius arm kit is listed for. The maker applies it to the F-250 and F-350 Super Duty, 4WD, diesel. It is a full suspension lift with shocks included: 2 front and 2 rear Performance shocks. Fabtech lists 40 in as the largest tire, and the largest listed pairing needs cutting. Adjustable cams on the radius arms allow an additional 1.5 degrees of caster adjustment. The kit parts per the maker are radius arms, front coils, a rear block kit with U-bolts, a track bar relocation bracket and a pitman arm. The rear lift blocks add lift, but the maker does not publish a rear height figure. The line has 1 part number and covers one truck family, the 2023-2026 Ford F-250 / F-350 Super Duty. A diesel-only condition decides fit before anything else.

Which part number is yours

K2413 is the only part number on this line, so the check is whether your truck matches its one listing. The application reads F-250 and F-350 Super Duty 4WD diesel, 2023 to 2026. The maker footnotes add three conditions: non dually models only, the kit will not fit gas models, and it does not fit vehicles equipped with the Ford onboard scale system. Fabtech lists 4WD only, so match the drive fitment as well as the engine. On the listing, look for the part number K2413, the diesel wording and the 2023 to 2026 range. The maker's footnotes do not mention the Tremor package, so ask the maker if your truck has it. For tires, 40 in is the largest size Fabtech lists, and that pairing needs cutting. The maker does not publish an install time or a rear lift figure for K2413. Because the kit includes radius arms, a pitman arm and a track bar relocation bracket, expect a larger parts count than a spacer kit.
