The Hellwig helper springs LP-25 (part # 2511, 2500 lbs) and LP-35 (part # 3511, 3500 lbs) fits the 2017 Ford Super Duty F-250 and F-350. Get yours installed at Marken Performance.
The Load Pro LP-25 and LP-35 helper springs allow Super Duty owners to better tow and haul heavy loads with improved safety, stability and comfort by maintaining a level ride height, improving overall drive control.
The progressive rate of the Load Pro Helper Spring also means that the helper springs aren’t activated until a load is present, allowing the truck to drive like stock when unladen. Additionally, the user can further dial in the load support for an uneven side load through the adjustable U-bolts.
The separate mounting hardware kit (part # 25301) includes all necessary parts and hardware.
