Here at Shockwarehouse, we carry many different products to help add support for towing and hauling. Chances are, if your vehicle squats in the rear when towing or carrying heavy loads, you have gone beyond what the stock suspension was designed to support. This can also be caused by worn out or weak suspension parts, such as coil springs or leaf springs.


There are several ways to add support and several choices as far as products. Here we will give them an overview to help you choose the best product to fit your needs or modifications.

NOTE: Obviously all of these products will NOT be available for every vehicle. Please look in our Online Catalogs to see what options are available for your specific vehicle. Manufactuers of these products recommend that you do not exceed the vehicle beyond it's original GVW specs.
