The 305 is not a casual bolt-on. The truck needs the right lift strategy so the tire can work through its full steering and suspension range without rubbing.
The 305 platform is meant to be fit correctly. That means tire, wheel, lift, and clearance all have to be handled together instead of treating the lift as an afterthought.
When we spec a 305 build, the lift path is built into the recommendation from the start, not added on at the end when a rubbing problem shows up.
These lift paths are aimed at the Ford Super Duty trucks most commonly paired with Founders 305 builds. The goal is a clean, usable fitment, not a sloppy compromise.
We treat lift selection as part of the overall conversion path, not a disconnected accessory sale. If you're building out a 305, we'll walk you through what the truck actually needs.
Two common Ford Super Duty approaches depending on the truck and whether track bar correction is needed.
The baseline leveling path for Ford Super Duty 4WD applications, coil spring spacers, isolators, and related hardware for a clean 2.5-inch front level. The right match when the truck can accept the 305 fitment without needing the added relocation-bracket package.
The upgraded path for Super Duty applications where front track-bar correction is part of getting the fitment right. More complete for trucks that need the additional bracket solution to finish the clearance job properly.
Tell us the year and trim of your Super Duty and we'll point you at the right lift and fitment path.
