How to Install the C-Section Kit in your Vehicle

How would you like your lowered vehicle with an increased rear axle travel and make your ride a little, say, more comfortable? If your answer is a resounding “yes,” then it's high time that you invest on a C-Section kit. The C-Section helps your vehicle to improve the rear axle suspension. When this part wears out, you can always choose to install a new one on your own. You can readily buy a C-section kit, complete with all the needed accessories.

Difficulty level: Moderate

What you'll need:

  • Jack and jack stands
  • Wheel chocks
  • Die grinder
  • Drill motor
  • Wrench set
  • C-clamps
  • Screwdriver
  • Cleaner and cloth
  • Replacement C-section

Step 1: Park your car on a firm, flat and level surface, ideally asphalt or concrete. Block your front wheels with appropriate wheel chocks. Put your vehicle in “park” mode. Wear safety glasses and personal protective equipment.

Step 2: Loosen, but do not remove, the rear wheel lug nuts. Lift the rear of your vehicle at least 6 to 8 inches above the ground. If your vehicle is a step-side model, remove the inner fender liners from the vehicle. Using the floor jack, lift the axle housing a bit to remove the load from the leaf springs.

Step 3: Remove the small rivet in the C-section from its mounting hole. You can find it on top of the left-hand frame rail just behind the fuel tank. Dispose the clip, and do not reuse it.

Step 4: Remove factory jounce stop by loosening and removing the nut using a wrench. It is located within the frame rail internal support. Clean the area with solvent to remove the factory coating.

Step 5: Using the steel template from the kit, align the slot with the one located on the left-hand frame rail. It is important that the template is aligned so that the C-section assembly fits over the frame rail properly. You can use a felt tip pen to mark the notch.

Step 6: Drill a hole through the frame centered on the mark. Use the die-grinder to cut the C-notch opening. Be careful not to remove or damage the other components behind the frame rail. Do the same to the right-hand side.

Step 7: Paint all bare metal surfaces and edges to prevent rust and corrosion.

Step 8: Install the outer C-section shell over the frame rail. Make sure that they are aligned and fit correctly. Use the drill motor to transfer the holes to the frame rail. Use the C-section holes to locate the drill bit.

Step 9: Insert hex head bolts with washers into the holes. Secure these bolts with washers and locknuts. Tighten and torque them to 110 lb. ft.

Step 10: Install the urethane jounce stop to the C-notch part of the C-section shell using the locknut. Install five tubular spacers over the threaded ends of the bolts.

Step 11: Reinstall the wheels and torque them based on the manufacturer's specifications. Make sure that all components and fasteners are properly aligned, installed, and torqued.

You can finish the installation in an hour or two, depending on your familiarity with your vehicle. It would help if you can ask someone to help you out during the removal and reassembly of your vehicle's components.
