Orion Motor Tech OMT 5x4.5 Wheel Spacers, 1 Inch Spacers with 1/2-20 Studs Compatible with Jeep Wrangler TJ YJ Grand Cherokee Ford Explorer Mustang Ranger, 82.5mm Center Bore Wheel Spacer Kit Set of 2

I purchased these spacers for my boat trailer and they worked exactly as expected. The fit was accurate, the machining is clean and the aluminum feels solid and durable. Installation was straightforward and the included studs made it easy to secure everything properly. Once installed, the wheels sat at the right clearance and the trailer tracked smoothly without any issues. I checked and re-torqued the bolts after the first use and everything remained tight. These spacers are designed for vehicles like Jeeps and trucks, but they have performed very well on my trailer. I will continue to check torque regularly but so far they have proven to be a reliable solution.

Harbor Freight (HFT) sells a 4X8' (48X96") "Heavy Duty" trailer kit (5 Lug Tires). It's just the frame only and the owner is responsible for fabricating sides (if they want). However, to have a true 4X8' internal dimension (for transporting plywood/sheetrock), the sides would have to stick outside of the frame (inline with the side pockets). This can cause potential issues with the tires hitting (rubbing against) the fender under load and causing the tires to shred. These spacers move the wheels out approx 1" giving enough clearance. I don't want to go any wider as it will put more stress on the hub The material is made from aluminum with pressed in zinc coated studs. Note the HFT trailer uses metric whereas these spacers come with 1/2-20 (SAW) studs pressed in. You can use the stock lug nuts from the trailer to secure the spacer to the hub. You might have to grind the studs on the hub (NOT THE SPACER) as they will stick past the surface of the spacer. For the price of these spacers it was worth the labor to me (Angle grinder with 60 grit pads). You can find similar spacers that are thicker that would prevent this. Besides that, the installation went very well.

Solid fit, perfect size for compatability with my Crown Vic LX, easy to install if you're comfortable with a cutting disc, and the durable material build was very promising.

First impressions are good, excellent value for the price. My only nitpick would be the provided lug nuts are on the cheaper side, but did fine at 120 ft-lbs. I’m running these on a utility trailer to clear bigger tires. I will update this review to 5 stars once I’ve had a chance to run them for a while.

They worked fine for my application however have a close look at the images, there is no "collar" for the wheel hub to centre on. The better spacer do provide this feature. If you choose to use these, know that the only thing centering the wheel will be the lug nuts. Which is likely fine for something light duty such as a garden trailer.
