Works well to bolt spare tire onto stock location on cargo platform of 2018 Cherokee grey wolf 26dbh, sounds like the lug nuts and bolts are different size from hardware on tires on trailer so docking one star for that.
by:
its what I needed and will work, only issue I seen was the shipping, it went to San Fransisco then to Denver instead of straight to Denver something is goofy with your shipping system
by:
Just what I needed in order to rebalance my RV spare on the bracket. I would recommend this site for those RV related items they carry in stock!
by:
Well, I got more nuts and washers for something? And the flat locking washers Don't work at ALL. Now I need to try to find them somewhere
by:
Parts missing from package. 24 hours from contacting customer service still no resolution. Package did not come with rectangular keeper pieces. Can not mount spare without them.

E trailer followed up on this request and fixed the order. I was unable to change 2 star rating. Definitely should have a higher rating based on positive customer service.

Perfect fit as described
by:
The product arrived in new condition. I have no complaints about the service, delivery or packaging. I suppose the quality was good, but it wasn't what I was expecting. The OEM carriage bolts in my spare tire carrier broke and I needed to replace them, which is why I ordered this item. The bolts in my spare tire carrier that came on my 2014 Evergreen travel trailer were 1/2-20 UNF thread which matches the threads on my wheels, so the same lug nuts that fit the wheels also fit the spare tire carrier. So that's what I thought I was going to get.
These bolts are 1/2"-13 UNC thread, so they require different lug nuts. There are some lug nuts supplied with the bolts, so I was able to use them, however, now the lugs are not interchangeable with those on the wheels. I have yet to find anywhere that I can purchase replacement bolts with the correct UNF thread and Evergreen is now out of business, so I;ve made do with these for now.

A year later Im still making do with these carriage bolts as I have been unable to find any with the 12 UNF threads. It would be nice to be able to use the same lug nuts on the spare tire carrier as on the trailer wheels, but that apparently is harder than it sounds as noone sells the matching bolts.

by:
This product did exactly what I wanted it to. Better than what came with my new trailer! That is why I bought this product in the first place. The trailer's spare tire setup came with a regular nut that did not have a conically shaped face and therefore didn't match the conical shape of the hole in the rim of the spare tire. Therefore a regular washer and lock washer were required. To add to the pain of use, the bolts didn't have any kind of separate retention. This caused all the pieces to fall to the ground when I unscrewed the nut from the bolt. I love the metal plate that keeps the bolt in place while you remove and put back the spare tire on the carrier!

Still working great!

by:
One of the carriage bolt/nut sets was fine but the other seemed to be defective. I couldn't get it started smoothly beyond a single turn no matter what I tried, and by the time I put it on all the way and took it back off, the carriage bolt broke cleanly in half. I contacted CS, who asked for a photo of product *before* I had put it together, which of course I didn't have, then offered no further help. Buyer beware I guess.

The carriage bolt should not have broken on you. I will have this re-reviewed so that we can have the broken bolt and nut sent back out to you. Please keep an eye on your email.

by:
Works great
by:
Fit my spare tire holder on my boat trailer. I liked the retaining clips that hold the wheel studs in place while you tighten down the bolts.

Its been a year now and so far so good. The spare tire mounting bolts are holding up great. No issues.

by:
Product is as described, my only issue is as noted in other reviews: the thread pitch and but size are not standard. The lug nuts supplied will only work on these bolts and likely not on your other wheel studs. Since the nut is a different size (3/4”) you may need two sockets to change a tire. That is extremely frustrating, but I couldn’t find the right replacement carriage bolts, lug nuts and retaining washers to replace the ones on my spare tire carrier. For the price, I’ll deal with the hassle.
by:
In addition to the above hardware my package my package contained the washers and nuts for the u-bolts that attach the (tire mount) to the trailer bumper. So because I had them, I replaced the nuts and washers on the bumper u-bolts as well because these had accumulated some rust. The Hardware appears to be zinc plated and should last in the years to come.

I also like the flat rectangular washers with the teeth that hold the carriage bolts in the mount so they won't fall out when you take the tire on or off.
Very satisfied!
by:
I looked high and low for these parts, and finally found them here. etrailer is now my "go-to" for trailer parts and specialty fasteners.
by:
Worked for my needs.
OEM provided nuts on spare tire were 21mm, while lugs on axles were 3/4". Always had to have two different sockets available. Buying this kit eliminated the need for the 21mm socket - thank you.
by:
Original bolts for spare tire for new Big Tex trailer were junk and cross threaded first use. This kit replaced original hardware perfectly to bolt spare tire on trailer mount.
by:
Our package included ONLY 2 bolts and 2 nuts - one of the nuts looked used with scrape marks and black lines. Neither of the nuts had the same thread count as the bolt! One was a fine thread, the other was coarse. Nothing useful - and now we wait for two weeks until they can get more stock.
by:
I’ve got a 40’ Gooseneck where the spare is stored above the neck. My original spare tire bolts seemed to have broke. I believe it’s due to me not tightening them down enough and the vibrations caused them to break. These bolts from etrailer are exactly what I needed. etrailer is my go to for trailer necessities
by:
Worked! Not sure why there were different size nuts and lock washers included, but the bolts/lugs/retainer clips worked great.
by:
Bolts are different thread, missing the speed nuts, absolute rip off
by:
I just received the items in the mail, and all is well. I do have a question however. There are 4 nuts with 4 lock washers, and none of them fit the 2 lug nuts that are a part of the package. Could someone tell me just what they are for?
