Compatibility: Compatible with all steel 2.0", 2.5", and 3.0" BulletProof Hitches featuring an 8" drop or greater. Frame-Mounted Hitch Stabilizer Draw Bars: This kit includes two heavy-duty steel bars that connect the bottom of the hitch to the frame rails on your vehicle, eliminating all leverage on the truck's hitch receiver. Adjustable Stabilizer Bars: The draw bars adjust from 29"-39" inches; they can be tightened to eliminate all slop and wobble from the hitch receiver, ensuring a solid and secure connection. Built to Last: Crafted from solid steel with our signature textured black powder coat for superior corrosion-resistance. Installation Requirements: Some fabrication may be needed depending on your hitch receiver design and spare wheel location; requires drilling one 5/8" hole in the hitch gusset and four 1/2" holes in the frame; drill bits are not included.
