| Year | Make | Model |
| 2008 - 2010 | Ford | F-250 Super Duty |
| 2008 - 2010 | Ford | F-350 Super Duty |
Note: For F-350 owners, see 'Notes' before purchasing
Designed by Carli, built by Deaver Spring MFG, this add-a-pack removes your lower overload leaf with thinner 1" gauge leaves. This proprietary design eliminates the harsh rebound associated with the OEM overload spring, while still maintaining payload capacity and improving overall ride quality.
Part Number: CS-FPAP-08
Features
- Compatible with 3.5" axle tube
- Progressive design addresses the harsh rebound of the factory overload spring
- Includes U-bolts and hardware
- Provides 2" of lift
- Load capacity is maintained, and ride quality is improved
Notes
- The rear of the Super Duty can be outfitted with a replacement Full Progressive Spring Pack (reduces capacity to a “light” ¾-ton) or this factory leaf-pack modifying Progressive Add-a-Pack. This is where the F250 and F350 are a bit different. Since 2008, the main spring packs on these two trucks have been different; the F250 has a lighter rate spring pack than its 350 counterpart.
- The F250 Add-a-Pack equipped systems are a nice improvement over stock; the F350 with the Add-a-Pack is still very stiff (in some cases, more so than stock) in the rear, as the main pack doesn’t move much unless loaded. For this reason, Carli DOES NOT recommend these be installed on an F350.
