2017-2026 Super Duty 4x4 XXHD +3500lbs Progressive Leaf Spring Kit - 1" Lift (CS-FFSP-LVL-17-XXHD)

Description

IMPORTANT - These will have a custom-order lead time AND require custom-tuned Pintop Shocks (different tuning than the XHD shocks) to support the massive rates and load capacity of these springs.

Specially designed for the massive flagship, off-road, or rescue truck, these springs are perfect for those who have custom flat-decks, large fixed campers, or utility boxes. These springs are massive and are only for those who have a 3,500 lbs constant load, and have been tested to handle trucks weighing over 11,000 lbs (over 6,000 lbs in the rear) with ease. If you're looking for heavy-duty, you've got it.

Part Number: CS-FFSP-LVL-17-XXHD
