Before purchasing, we HIGHLY recommend you going to a weigh bridge, with the setup that you drive around with 80% of the time and then working out how much additional is over the back axle compared to stock then picking a spring pack to suit this weight.

Our kits are biased towards performance and not towards load carrying. If your truck regularly see's large changes in loads, we recommend other leaf spring products would be better suited. 

We will also have a specific Airbag kit in conjunction with Boss Airbags which will help with large load variances.
