Improves Load Handling and Stability when Towing and Hauling
Even though your 2008-2010 F350 is a tried-and-true towing machine, your truck starts to sag and experiences stability issues long before its GVWR becomes an issue. To help win you back control and handling when your truck is loaded up with gear, you’ll need the SuperSprings Self-Adjusting Helper Springs. This hand spring kit consists of two leaf springs that attach to your stock springs using bolt-on shackles and give you an additional 4000lbs of load capacity so that you can tow and haul big loads without suffering from sag, sway, or general instability. The SuperSprings helper springs are easy to install and come with everything you need to get them up and running on your F350.
High-Strength Leaf Springs with Easy, Bolt-On Installation
The SuperSprings Self-Adjusting springs are made out of durable materials and are designed for a hassle-free install. Each actual spring is made from high-strength 5160H spring steel that’s then shot-peened to relieve stress and extend the life of the entire spring assembly. Each one of these kits comes with a polyurethane block that installs on the upper u-bolt bracket and allows the SuperSpring assembly to ride on top of your factory leaf pack with minimal amounts of NVH during normal operation. The SuperSprings come fitted with adjustable shackles that install around your stock leaf springs without the need for any drilling, trimming, or other permanent modifications. Each kits comes with installation hardware and instructions. Fitment:
