About This Product
This fifth wheel hitch drops directly into factory OE pucks. No adapter needed. If your truck came with the fifth wheel prep package, you have pucks in your bed ready to accept this hitch.
Straightforward construction focused on reliability. Secure jaw grip, height adjustment, durable finish. Gets the job done without unnecessary complexity.
Twenty-one thousand pounds is enough for most people. Unless you are towing something genuinely massive, this capacity covers it with room to spare.
UMS flexibility is useful if you change trucks or move hitches between vehicles. Verify this configuration matches your setup.
