Store more cargo when riding your quad in a lockable cargo box. The standard cargo box is designed to be mounted on the rear rack of many ATVs with four U-shaped bolts for permanent mounting (drilling into the floor of the box is required to do this). The quad cargo box is made of a high density, molded polyethylene with a uniform thickness that allows it to be super strong and durable. With a tongue and groove style lid system and space inside the box lid, the cargo box has a vast amount of space to get as much cargo on your quad as possible. An easy-to-use locking latch system keeps the lid on the quad box secure and closed.

This quad cargo box not only allows for more storage space on an ATV, the box also features a black cushioned backrest. Two red, plastic reflectors on the rear of the quad box provide better visibility at night. One set of two keys are included to lock the box to deter theft. The cargo box comes with a one year warranty.

5 Stars Great Locking Storage Box!

Grant from WI wrote (September 17, 2016):

I was very pleased with this purchase! When ordering on-line you can sometimes be surprised by what you believe you have purchased and what actually arrives, but not in this case! This storage unit is well made, using heavy material, and has sturdy construction. There is plenty of room for the necessary tools and other accessories needed while out on the trail, plus it still has room for two helmets. Easy to install. Just lay it out where you want it positioned on the rear rack, take a couple of measurements, drill holes, and install the provided mounting hardware. Looks great! The locking feature is a plus! Very fast delivery! Had mine within 2 days of ordering. Hats off to Discount Ramps for superior customer service and offering great quality products. Will definitely recommend their products and web-page.

This is the best ATV luggage box that I have come across. It has superior thickness extremely sturdy. The the lid comes hinged with big sturdy hinges that have stops to prevent it from falling completely open. The latches are stainless steel with key locks fastened with aluminum rivets .

5 Stars Great back rest and storage unit

Sharon from IA wrote (August 15, 2015):

We bought this to make a back rest for me when riding ATV trails in Colorado. It worked great, it was comfortable and helped keep me feeling secure while riding on trails. My grand daughter asked why we hadn't got this sooner.

5 Stars Very Happy with purchase - perfect

The product arrived very quickly and in excellent condition. It is very roomy for storage and very comfortable to lean on your back. Also it is a great fit for a petite person sitting on the back of the Polaris.

4 Stars Terrible Latches

Chuck from CA wrote (April 08, 2015):

The box is great and seems very sturdy. The latches are very cheap and first time out on the trail I had to fight with the latches to open and close correctly. I will be changing these out with Rubber latches bought from E-bay

5 Stars Perfect for my needs.

Really nice box, heavy duty construction. Very easy to install. Just had to mark out drill a few holes and bam all done in less the 20 minutes. And the looks are appealing on my 2014 yamaha grizzly tactical edition.
