Zone Offroad 2.5-Inch Leaf Spring Leveling Kit | 5-Leaf Mini-Pack | 2000–2004 Ford F-250 / F-350 Super Duty 4WD | SKU: ZONF4

The Zone Offroad 2.5-inch leaf spring leveling kit (SKU: ZONF4) raises the front of the 2000–2004 Ford F-250 and F-350 Super Duty 4WD by 2.5 inches using a 5-leaf progressive-rate mini-pack, eliminating the factory nose-down rake while improving ride quality and increasing front load support. This is a full front leaf spring replacement — not a spacer. Does NOT fit 2005 or newer Super Duty — different platform. Does NOT fit 2WD F-250/F-350. Does NOT fit F-150. Contact OFAS at 903-347-3875 to confirm fitment before ordering.

Leveling Kit vs. Lift Kit — What This Kit Does

A leveling kit raises the front of the truck to match the rear — eliminating the factory nose-down rake. This is not a lift kit. The Zone Offroad ZONF4 raises the front 2.5 inches only — the rear height is unchanged.

5-Leaf Mini-Pack — How It Works

The 2000–2004 F-250/F-350 Super Duty 4WD uses a leaf-spring front suspension. The Zone Offroad 5-leaf mini-pack replaces the factory front leaf spring pack with a 5-leaf progressive-rate assembly that raises the front 2.5 inches while improving ride quality and load support.

• Progressive spring rate: Softer initial rate for improved small-bump compliance — stiffens progressively under load to maintain height and control
• 5-leaf design: More leaves than the factory pack — increased load support reduces front-end sag under accessories, plows, or heavy equipment
• Full spring replacement: This is not a spacer — the factory front leaf spring pack is removed and replaced with the Zone Offroad mini-pack
