Start with the factory overload springs your truck already has, then confirm the right StableLoad with Find Your Fit.
Before you buy anything, look under your truck. If your truck came with factory overload springs, it already has the heavy-load support StableLoad is designed to activate. StableLoad helps those factory overload springs engage sooner, so the real question is not whether to add a system, it is confirming the right StableLoad for your exact truck.
As an online product-selection resource and towing equipment provider, Torklift Central helps you confirm fitment with Find Your Fit before you order, so the product matches your suspension the first time.
Do You Have Factory Overload Springs?
Many heavy-duty trucks include factory heavy-load support in the form of factory overload springs, a secondary set of springs near the main leaf pack. The factory leaves a gap so they do not stay engaged when the truck is empty, which keeps the ride comfortable but lets the truck settle before they support the load. StableLoad closes that gap by helping the overload springs engage sooner. Because it is designed to work with those springs, confirming that your truck has them, and how they are configured, is the starting point.
Upper, Lower, and Drill Versus No-Drill
StableLoad comes in configurations for different factory setups, and which one fits depends on your truck. Some trucks use a StableLoad for the lower overload spring and others for the upper, and the correct choice follows your factory suspension. Installation requirements also vary by application: many fitments are no-drill and if the application requires drilling there is a free drill tool available to assist with the installation. These details are set by the current product instructions for your application, so confirm them rather than assuming.
The lower StableLoad also offers the Comfort Mode and Control Mode on and off settings, which let you engage load support when the camper is loaded and disengage it for a factory ride when the truck is empty.
Confirm Your Fit With Find Your Fit
Use the Find Your Fit tool to confirm the correct StableLoad part number for your truck year, make, model, trim, bed length, cab style, and drivetrain. This is the reliable way to match your truck to the right configuration and the right installation requirement.
If your truck has aftermarket suspension parts, such as airbags, add-a-leaf kits, replacement springs, or a lift, disclose them, since they can change which product applies. Clear photos of your rear suspension and overload spring area help our retail specialists point you to the right fit faster.
Ratings notice: StableLoad products are designed to help your truck support a load when they are properly matched to your vehicle, but they do not increase your truck's payload, GVWR, GAWR, tow rating, axle ratings, or tire ratings. Always stay within every factory rating. The lowest-rated component in your setup determines your usable limit, and a load-support product does not make an overloaded truck safe.
