Suspension Block

 Shop Suspension Block

The most common type of modification done on trucks, SUVs, Jeeps, and offroad vehicles is a suspension lift. Lifting a vehicle basically increases an automobile's center of gravity, which reduces its maximum safe operating angles. It also gives a vehicle the ability to accommodate larger wheels or tires. There are several types of suspension lift kits available in the market today. And one of the most common is a suspension block. This particular type of suspension lift is very simple, and it basically works by lifting the rear part of the vehicle to achieve a desired height. This is done by installing a block between the leaf springs and axles. These components are then secured in place by longer U-bolts. When choosing a lift kit for your vehicle, you need to make sure that you get one that matches the specs of your ride. This not only ensures easy installation but also guarantees optimum performance on the road. Just remember that the type of kit that you are going to buy should match the drivetrain of your ride. Here's a brief and basic guide that will help you with your suspension lift woes.

How to Install a Suspension Block

Step 1: Before you begin the lifting process, make sure that your vehicle is parked on a flat-level surface. After that, get your vehicle's ride height, measuring both sides from the bottom part of the wheel to the lip of the fender.

Step 2: Once you're done measuring, turn the engine off and engage the parking brakes. As an added precautionary measure, secure the wheels using wheel chocks.

Step 3: Next, focus on one side of your vehicle and remove the U-bolt nuts and washers.

Step 4: After that, raise one side of the vehicle via the leaf springs until you have enough space to install a block kit. You may need a 3-ton jack and a solid spacer like a block of wood to be able to raise it.

Step 5: When one side of the vehicle is already raised, think about the amount of lift that you want to try on your vehicle and then set the components according to this height.

Step 6: After that, lower the jack that's attached to the vehicle very carefully to make sure that the lifting spring's centering pen is positioned properly.

Step 7: Next, find the mounting hardware included in the suspension block kit, install the new U-bolts, and toque the components using the vehicle's mark.

Step 8: Repeat the directions above for the other side of your vehicle.

Step 9: Check the following components in your vehicle: adequate clearance and the steering.

Step 10: After that, align your vehicle all by yourself or by taking it to an expert alignment technician.

Step 11: Lastly, adjust the headlight aim and make sure it fits your driving style.

How to Maintain a Suspension Block

  • Always remember to inspect your suspension block during your routine maintenance.
  • Always check and re-torque your vehicle's U-bolt fasteners after 500 miles.
  • As much as possible, avoid unnecessary and abrupt maneuvers, sharp turns, and other driving conditions that could lead to damage.
