Carli CS-FLVLSPKG-CS20IFP-A 2.0 IFP Shocks FSP for 2005-2024 Ford F250/F350 4x4

Vehicle Fitment

• 2020-2024 Ford F250/F350 4x4, Diesel - 3.5" lift configuration
• 2005-2019 Ford F250/F350 4x4, Diesel - 2.5" lift configuration

Fitment Notes

• FSP valving is specifically tuned for Carli Full Progressive Leaf Springs - this is NOT the correct shock for stock leaf springs or Carli's Progressive Add-A-Pack (those require the PAP-valved variant instead)
• Lift height pairing varies by model year: 2020+ trucks pair with a 3.5" lift, while 2005-2019 trucks pair with a 2.5" lift
• Confirm your rear leaf spring configuration before ordering to ensure the correct valving is selected

Product Description

The Carli CS-FLVLSPKG-CS20IFP-A is a Carli SPEC 2.0" internal-reservoir shock package for 2005-2024 Ford F250/F350 4x4 diesel trucks, valved specifically for use with Carli Full Progressive Leaf Springs. The 6063 aluminum, anodized shock body pairs with 5/8" hardened, chrome-plated shafts and premium 5WT oil to deliver consistent, all-around comfort for daily driving, towing, and hauling, whether paired with a 2.5" lift on 2005-2019 trucks or a 3.5" lift on 2020+ trucks.

Front shocks use a longer reservoir hose routed to a frame- or coil-bucket-mounted Carli bracket, while the rear shocks use a piggyback-style mount, both finished with matching CNC'd clamps for a clean, brand-consistent look. Because valving is matched to the rear spring setup, it's important to confirm you're running Carli's Full Progressive Leaf Springs before ordering this FSP variant - trucks with stock or Add-A-Pack rear springs need the differently valved PAP version instead.
