The Carli Deavers – they’re synonymous with the elusive “buttery” ride quality touted by Carli-equipped HD enthusiasts. With this rear compliance comes capacity degradation. It wasn’t much to talk about when we started offering our version of the Deaver Spring; you remember… back in the day that a 3/4-ton carried, well, 3/4’s of a ton and a 1-ton, 1-ton. Reduction in hauling capacity for these trucks would drop them from a respectable 1,500/2,000lbs closer to the 1,000-1,200lb area.
New truck capacities have gotten out of hand. The new F-250 boasts a whopping 2,462lbs – 4,323lbs in bed capacity, depending on configuration. The Carli Deavers, well, they’re still hanging their hat on good ol’ “Light 3/4-ton Capacity.” Deaver has always shied away from throwing a number at it for the same reason Ford varies about 80% within the same platform: it’s motor, cab and configuration dependent. In most applications, this is a non-issue. We’ve been making Long-Travel airbags to supplement our reduced capacity springs back to factory capacity nearly as long as our springs have been available.
Unfortunately, there are a couple applications for which we don’t make a load supplements but offer reduced capacity leaf springs; namely, the 2014+ Ram 2500 and 2011+ Ford Super Duty in the Leveling configuration. For these, we load-test them and provide customers the data to ensure the products will suit their applications. This test is on the L18 Spring or, as you all know it, the Leveling Leaf Spring (FFSP-LVL) for the 2008 to 2021 Super Duty!
