This is not a lift kit — it is a suspension system conversion. The factory radius arm and coil spring setup is replaced entirely with a true 4-link coil-over system. The result is corrected geometry at 6-inch lift, eliminated radius arm bind that degrades factory suspension under articulation, improved front axle articulation, and FOX 2.5 PE damping with external reservoir tuned specifically for the 6.7L Power Stroke's front-end weight distribution.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe FOX 2.5 PE coil-over integrates spring and damper into a single unit — replacing both the factory coil spring and shock simultaneously. The 2.5-inch body carries greater oil volume than a standard shock, and the external reservoir adds additional fluid capacity for sustained thermal management under diesel towing loads. Advanced valving delivers consistent damping across a wide range of speeds and terrain inputs — not just on the freeway empty, but loaded and pulling.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe comparison between 1987FPE and 1997FPE is lift height and engine. SKU 1997FPE delivers 4 inches of front lift on the F-350 DRW gas platform. SKU 1987FPE delivers 6 inches on the DRW diesel platform. Both run FOX 2.5 PE and true 4-link conversion geometry. The diesel adds the weight and towing load requirements that make the diesel-tuned coil-over spring rate and damping valving a hard requirement — not a preference.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eThis kit is for you if:\u003c\/strong\u003e You own a 2020–2022 F-350 Super Duty DRW 4WD diesel and want 6 inches of front lift with a complete 4-link coil-over conversion — corrected geometry, eliminated radius arm bind, improved articulation, and FOX 2.5 PE damping tuned for a working diesel DRW platform.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eThis kit is not for you if:\u003c\/strong\u003e Your F-350 is gas — order SKU 1997FPE.

The differences are lift height and engine — 1987FPE delivers 6 inches on the DRW diesel platform and 1997FPE delivers 4 inches on the DRW gas platform. Diesel-tuned coil-overs in 1987FPE are spring-rated and valved for the 6.7L Power Stroke's front-end weight. These kits are not interchangeable. Call \u003cstrong\u003e(469) 407-7538\u003c\/strong\u003e to confirm which applies to your truck.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eWhy does a 4-link conversion matter over a standard radius arm lift on the F-350?\u003c\/strong\u003e\u003cbr\u003eThe factory F-350 Super Duty front suspension uses a radius arm design. Under significant lift, radius arms introduce caster deviation and bushing bind that degrades geometry consistency, increases tire wear, and reduces articulation. A true 4-link setup replaces the radius arm geometry entirely — correcting caster at the lifted height, eliminating bind under articulation, and allowing the suspension to move through its range of motion without the geometric compromises inherent in a lifted radius arm system. At 6 inches of lift on a DRW diesel platform used for towing, that geometry correction is not a luxury — it is the foundation of the build.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eDoes the diesel vs. gas distinction actually affect the coil-overs?\u003c\/strong\u003e\u003cbr\u003eYes. The 6.7L Power Stroke diesel engine carries significantly more front-end weight than the gas engine. Coil-over spring rate must be tuned for the specific front axle weight it supports. A gas-tuned spring rate under a diesel sags and produces incorrect ride height and compromised geometry under load. Diesel-tuned springs under a gas engine produce excessive spring rate and harsh ride. The spring and damping tune is not interchangeable between engine applications — this is why 1987FPE and 1997FPE are separate SKUs.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eIs the driveline inspection required at 6-inch lift?\u003c\/strong\u003e\u003cbr\u003eYes. At 6 inches of lift on a DRW diesel platform, driveshaft angles change significantly from factory. U-joints operating outside their designed range under diesel towing load wear rapidly and can fail at highway speed. The inspection determines whether driveshaft modification is required for your specific truck's configuration. It is not optional.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eDoes this fit my 2023 F-350?\u003c\/strong\u003e\u003cbr\u003eNo. The 2023 F-350 Super Duty has different specifications — this kit does not apply.
