Feature: If you want your truck to drop 4 inches or less, this C-notch kit provides the clearance needed for a steep drop. You'll get an additional 3 inches of rear suspension clearance and provide better support strength to your frame.
Premium Performance: The 1/4" thick steel construction provides sufficient strength and durability for this frame. The frame is electrophoresis black and this kit will match your vehicle very well. This kit may not work with some spring and coil kits.
Package: Note that instructions are not included. The C Notch Kit includes frame plates, bump stops and hardware.
Installation: Before installing, you need to cut off the old frame. You can install it directly with bolts, or proper welding will make it stronger.
