The 4-link conversion is the same in principle across both: corrected caster, eliminated radius arm bind, improved front axle articulation, and 6-bolt driveline indexing for proper U-joint operating angles at the lifted height. FOX 2.5 PE with external reservoir delivers the top damping tier available for this application — extended thermal ceiling under sustained diesel towing loads, advanced valving for precise damping response across the full operating range of a loaded Ram 3500.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe distinction between 1667FPE and 1670FPE is axle configuration — not shock tier, not lift height, not geometry. Both kits deliver the same 4-inch 4-link result with FOX 2.5 PE. The axle configuration is the only variable that determines which SKU applies to your specific truck, and it must be confirmed before ordering.
