PRODUCT EVALUATION: DRIVE-OVER CHOCK

— Peace of mind while trailering your rig By the staff of Dirt Wheels —

The DOCs worked well with the ratchet straps to keep the RZR XP 4 Turbo planted when transporting it. When loading, we suggest having the machine in four-wheel drive if applicable. These would work well with any type of machine—from sport quads, UTVs and even golf carts.

Having your machine securely fastened to your trailer is not only good for your machine, it’s good for your sanity and the safety of yourself and others while driving down the road. We’ve all been there a time or two: we get out of our vehicle after driving down a beat-up road and, despite tie-downs, our machines have moved on us during transport. It’s not a good thing, especially if you have no back gate, or are hauling multiple vehicles. The worst is having it come off the trailer. Before we would say to use plenty of nice tie-downs that have the correct weight rating or use the tire-strap-style tie-downs instead. That was until a new company hit the scene and the Drive-Over Chock (DOC) was born.

Before installation, it’s crucial to get the chocks loaded on the trailer where you would like it mounted to. We suggest the farthest forward position.

WHAT DOES IT DO?

What the Drive-Over Chock does is in its name: it’s a large piece of strong rubber that has ridges for traction and is designed in an almost triangular design. They will work with virtually any machine, including UTVs, ATVs and even golf carts. The original Drive-Over Chock, which retails for $69 for one DOC, is 4 inches tall, 6 inches wide and 72 inches long. If you’re looking for something that’s more heavy duty, the Heavy-Duty Drive-Over Chock retails for $129 for one DOC, is an inch taller than the original at 5 inches, but the other dimensions are the same. To achieve the best trailering security, we suggest picking up two DOCs for UTVs and one DOC for an ATV.

DOC suggests mounting the chocks with a small gap between it and the tire. We mounted the 5-inch heavy-duty DOC up front and the original DOC on the rear tires.

“CHOCK” IT UP FOR A WIN

For this evaluation we went with the new Heavy-Duty DOC—for the front tires and the standard one for the rear tires. Installation is simple, and since we drive more two-seat cars than four-seat models, we set the spacing for those UTVs.

We first drove a Polaris RZR Turbo onto the trailer until the front tires touched the front frame bar on the trailer. We then slid the DOCs behind the front tires and rear tires. We then used a pen to mark the outside edges of the DOCs on the wood deck and removed the UTV from the trailer. Utilizing the long lag bolts provided in the kit, we screwed them into the deck of the trailer to secure the DOCs.

Once you have the DOC where you want them, it’s time to use the supplied large lag bolts. We used an impact gun to seat the bolts to the DOC quickly, but hand tools can be used.

An easy test to see if they were sturdy was to just drive the RZR over them in AWD. They were rock solid. We put the RZR in neutral and tried to move it by hand with four people pushing, and we couldn’t get it to roll over it. Once we had the RZR securely over the DOCs, we tied it down with ratchet tie-downs and hit the road. We took the trailer down a long washboard road that has made machines get out of shape in the past, but now with the DOCs, we’re happy to report that there was zero movement. As advocates for safety and by recommendation from DOC, we didn’t transport the RZR without tying it down, but we’re guessing it would take a lot of momentum for it to go over the DOC while in park.

If you want to haul your machines more securely, the DOCs are the hot ticket! To order your own DOC, visit www.driveoverchock.com or call (800) 676-DOC9.
