Skyjacker FR94S Softride Rear Leaf Spring 1999-2007 Ford F-250 F-350 Excursion

Vehicle Fitment

• 1999-2007 Ford F-250 Super Duty (4WD, Gas & Diesel) - Rear, 4 in. Lift
• 1999-2007 Ford F-350 Super Duty (4WD, Gas & Diesel) - Rear, 4 in. Lift
• 2000-2005 Ford Excursion (4WD, Gas & Diesel) - Rear, 4 in. Lift

Fitment Notes

• Fits rear leaf spring position only; all supported applications are 4WD - this spring is not designed for 2WD configurations
• Sold individually - one spring per package; purchase two (2) for a complete rear axle pair
• Factory overload springs cannot be retained when installing the FR94S - the arch profile of the new spring is incompatible with the factory overload leaf geometry
• Covers the full P2-generation Ford Super Duty (1999-2007) in both F-250 and F-350 configurations, plus the Ford Excursion which shares the same rear spring platform
• The 1999 model year is the first year of the P2 Super Duty platform - earlier F-250 and F-350 (pre-1999) use a different spring; see Skyjacker FR56S for those earlier years
• For higher lift heights on the same platform, Skyjacker FR98S provides 8 in. of rear lift; FR94S is the mid-range 4 in. option
• Premium freight item - due to size and weight, additional freight and handling fees apply at time of shipment
• Professional installation and post-install alignment by a qualified shop are strongly recommended

Features

• Skyjacker Softride technology - leaves are tapered over their entire length, creating more flex at the leaf ends for a smoother, more progressive spring rate compared to conventional constant-thickness multi-leaf packs
• Progressive multi-leaf pack construction (4 leaves + overload + shim) delivers GVW rating and load-carrying capacity equal to or greater than OEM factory specifications for these heavy-duty platforms
• Individual leaves are shot-peened with high-velocity hard steel pellets, compressing the steel surface to increase tensile strength and maximize wheel travel without shortening spring service life
• Bolt-style spring clips eliminate inter-leaf friction and binding; conventional cinch-style bend clips that cause stiction are not used
• Tapered leaf design distributes load forces more evenly across the spring's length, reducing the tendency of one leaf to dig into the leaf above it and extending service life
• Pre-compressed under hydraulic pressure after manufacturing to preset the arch and significantly reduce fatigue sag in service
• Baked-on powder coat finish provides durable, long-lasting corrosion protection on- and off-road
• Manufactured from high-quality American steel - Made in USA
• Vehicle-specific engineering ensures correct spring geometry, pinion angle, and axle alignment at the 4 in. lift height on these Super Duty and Excursion platforms
• Compatible with 35x12.50 tire fitment on supported vehicles at the 4 in. lift height
• Backed by Skyjacker's Limited Lifetime Warranty against defects in materials and workmanship

Product Description

The Skyjacker FR94S is a Softride Rear Leaf Spring delivering 4 inches of rear suspension lift for the 1999-2007 Ford F-250 and F-350 Super Duty 4WD and the 2000-2005 Ford Excursion 4WD - all of which share the same P2-generation rear spring architecture. This positions the FR94S as a purpose-built rear spring for the first generation of the modern Super Duty platform, one of the most popular and capable full-size truck lines ever produced. At 4 inches of rear lift on a 3-inch-wide spring with a 105/8-inch free arch, the FR94S is dimensioned for meaningful off-road and overland clearance while retaining the load-carrying capacity demanded by these heavy-duty platforms.

Built on Skyjacker's Softride technology, the FR94S uses tapered leaves producing more flex at the spring ends than conventional constant-thickness designs, delivering a more progressive and compliant ride without compromising the capacity rating these trucks require for towing, hauling, and payload. The 4+Overload+Shim leaf pack configuration matches the structural demands of the Super Duty and Excursion rear axle, maintaining GVW-equivalent load capacity after installation. Shot-peening of individual leaves increases tensile strength, and bolt-style spring clips replace the friction-inducing cinch clips used in conventional spring packs. An important installation note: the factory overload springs cannot be retained alongside the FR94S due to the difference in arch profile - builders should plan for their removal as part of the installation.

The FR94S is sold as a single spring - two are required for a complete rear axle installation. It is a premium freight item due to its size and weight, and carries additional shipping and handling fees. Post-installation alignment by a qualified shop is strongly recommended to ensure correct pinion angle and axle geometry at the new ride height. For those requiring more rear lift on the same platform, the Skyjacker FR98S provides 8 inches of rear lift. Backed by Skyjacker's Limited Lifetime Warranty for the original retail purchaser.
