• General Questions

  • WHY IS THE SPACER IN THE KIT THAT I RECEIVED NOT THE SAME THICKNESS AS THE LIFT THAT I ORDERED?

    Sometimes, the spacer thickness is less then the advertised lift due to the motion ratio of your vehicle. Most lift kits are designed on the principle of motion ratio, so even though the spacer is small, it will give you a full amount of lift. The way this works is once you install the spacer, it will be changing the angle of the lower control arm, steepening the angle, and that will account for the additional lift, so once you install it you will see the full amount of lift height.

     

    HOW DO I DETERMINE WHICH KIT I NEED TO LEVEL MY VEHICLE?

    The ride height of each vehicle varies with each make and model. To level your vehicle, you need to first figure out the current height of our front and rear. Measure from the center axle to the top of the wheel well. Now subtract the lower measurement from the higher measurement and this number will tell you what lift kit to purchase.

    Example: If the front height is 18" and the rear height is 20". 20-18=2". So you would need a 2" front leveling kit to level out your vehicle.
    
    For more information read our Lift Kit 101 blog HERE.

     

    WHY AM I LIFTING MY TRUCK HIGHER IN THE FRONT?

    This has to do with the factory rake of your vehicle. The rear lift is higher than the front for factory models. So our full lifts kits allow you to level out your truck making it look much better.

     

    CAN I USE THIS KIT ON TOP OF ANOTHER SUSPENSION LIFT KIT?

    Our suspension lift kits are designed and tested to work with factory suspension components ONLY and should never be used on any vehicles with a suspension lift kit already installed. However, our suspension lift kits can be used in conjunction with a body lift.

     

    DO I NEED TO GET EXTENDED SHOCKS FOR YOUR KIT?

    SDT Leveling and Lift kits are designed to work with OE suspension components, so extended shocks are not required to get the kit installed and achieve your lift.

    However, vehicle manufacturers recommend replacing shocks or struts at 50,000 miles. So if your vehicle is past this, or getting close to, it may be in your best interest to replace them at the time of installation.

    In addition to this, while not required, extended length shocks will allow the suspension to articulate more and provide the most benefit from your new lift kit. 

      

    AFTER INSTALLING YOUR KIT, WILL I HAVE ISSUES WITH BALL JOINTS POPPING OUT?

    Street Dirt Track kits are designed to work in conjunction with factory components. your ball joints will still function properly once the kit is installed
