Average Customer Rating:  4.9 out of 5 stars   (84 Customer Reviews)

This round rubber bumper protects the rear of your trailer and provides cushion for your cargo as you load and unload.


As far as I could find this bumper was the only one with the exact hole spacing needed for my horse trailer. Easy to cut to length with a sharp Stanley knife, easy to install, I was thrilled that the metal plate for installation slid in perfectly and I didn't have to mess with that at all. Super happy how it turned out!


Easy to order and received quicker than expected. The holes matched up to the existing holes on an older Titan trailer. We trimmed off the excess with a cordless handheld saw.


Easy ordering, quick shipping, reasonable pricing, great reviews, trailer bumper fits our 2004 trailer to a tee. Awesome experience and customer service.
Thank you


I am very happy with the fit and quality of this bumper. I used it to replace the damaged one on my 2004 Morgan Built horse trailer. Though I needed an 84" instead of 96' I was able to use it by sawing about eight inches off one end making the new one two inches longer on each end than the original so that it covered more of the width of the trailer. The long slotted steel strip from my old bumper slid nicely into place to lay flat against the back wall of the bumper providing a good surface for the nuts to tighten against. The cut-out holes lined up perfectly with the existing studs and were large enough to get my aging girly fingers into in order to thread the nuts onto the studs. The whole arrangement is as secure as the original. I consider this bumper a good value.


Fit our Cimarron perfectly! It is tuff too. Horses step on it constantly while unloading and it doesn’t stuff or rip. Takes some patience to install and I recommend replacing the inner strip of aluminum. Take your time and drill holes in aluminum as carefully as possible!


My wife was very happy to have a new one on her trailer so the horses wouldn’t get hurt if they bumped their legs against it. Installing went good. Had to redrill holes. Old one was 9 1/2” center. Also had to get longer bolts because new bumper was a little thicker on the mounting side. Overall very pleased with the product. My wife says maybe we will have to get some new wheels also. I don’t think it ever ends haha


very easy to install

Highly satisfied with the company and the customer service provided etc.... Would recommend the site and or products to anyone such as friends or family. My husband and I have been camping with our horses for the last 15 years. Last fall we bought a new horse trailer and it came with a ramp. After several close calls with the ramp and the final straw last weekend when my husband gelding slipped on the ramp and fell on his side we where going to cut it off with a torch. I found your site and your product was exactly what we needed to replace the ramp to our trailer without compromising the looks or value of the trailer. I received the bumper before expected and was exactly what was represented on the site...


Awesome bumper! Installed on a 1960"s homemade trailer that previously did not have one. The hardest part was drilling for the bolts. It cut very easy with a reciprocating saw.


Why did I wait so long? Why.did I dread doing this? 10 minutes total time. Battery drill for bolts and sawsall with metal blade to cut off ends. 11 inch oc lined up perfectly. Slam dunk. Thank you etrailer!


This bumper is exactly what we needed! I simply cut a 42” piece from each end with a hand saw. The predrilled holes were a perfect match for our trailer.


Worked great


Excellent!!! Arrived on time!


Ordered, received promptly, as it should be.


We received our order in a very timely manner and the item was exactly what we needed. We will definitely be ordering more items from your company if/when the need arises.

Its working great! It shows no signs of wear. Thanks for a high quality product.

This is the 2nd one of these I have installed. After cutting it to size I used drill screws with some fender washers to attach it and it was no problem.


the bumper is of great quality and looks great on my trailer and my horses appreciate the safety it provides.


Great product


Bumper lined up, but my old self tapping screws needed replacing. I used self drilling screws and had to move the bumper off the original holes since some were stripped out. It would be nice if you offered self drilling screws along with the bumper. The ones you carry are too short.


This is a very nice heavy bumper and was easy to install


I was super happy at how fast my order arrived. It also was exactly the right product and fit! I live in Hawaii so for this to come so fast and at a decent shipping price will make me return for more trailer parts every time! 5 Stars

Thank you


Rubber bumper was perfect.
Came in weeks
faster than estimated ship date.


So far it seems ok. Haven't installed it yet. I will say though that I wish they would have drilled the holes closer to centered.

Its ok. It does what it should.

Great quality product . Easy to install. I used portaband saw to cut to length. Used pre drilled holes and used a standard hole saw where I needed extra holes, along with standard drill bits. The material drills and cuts perfectly. Nice quality product. This was being used to replace my work out bumper on my horse trailer. Looks like oem replacement .


I bought several items to repair and update my Titan horse trailer. These included chrome lug nuts and hub covers for the wheels and a bumper for the back of the trailer. The items were delivered extremely quickly and we'll packaged. All the items were exactly what I wanted and as they were presented. I am very pleased and will purchase from this company again

  • 96" Rubber Bumper Needed with Pre-Drilled Holes
    We have exactly what you are needing with part # D3-96 when it comes to the bumper. This is a pre-drilled round rubber trailer bumper that is 96" long (8') and has 9 holes drilled that as 11" apart on center and take 9/16" bolts. Unfortunately we do not carry any steel support bars with these specs so you would need to source that elsewhere. Attached is an installation video for you to reference.

  • Could Pre-Drilled Round Rubber Trailer Bumper # D3-96 Replace Bumper with Different Hole Spacings
    What you'd want to do is drill holes in the Pre-Drilled Round Rubber Trailer Bumper # D3-96 to match the mounting holes of your trailer and you'd be set. The bumper is rubber so it would be easy to drill. The pre drilled holes of this are 11 inches apart so it wouldn't match perfectly.

  • Is the Redline Pre-Drilled Round Rubber Bumper D3-96 Made of Soft or Hard Rubber
    I went to our warehouse to personally handle the Redline Pre-Drilled Round Rubber Bumpers # D3-96 for you so I could advise you on their stiffness. These bumpers are quite firm. When I applied my palm to the bumper and leaned as much of my body weight as I could onto it, there was almost no compression at all. So this is by no means a soft or squishy product. I would say it is perfectly suitable to use in a boat slip to prevent hull damage or for similar applications.

  • Replacement Rubber Bumper for a Trailer
    The holes on your existing bumper seem to be about 11 inches apart. The holes on bumper # D3-96 are also 11 inches apart. You may have to drill a hole or two to get it lined up with the first hole but then it should line up nicely. I have also included a link to the right that will explain how to estimate shipping cost.

  • Can the Pre-Drilled Round Rubber Bumpers # D3-96 be Trimmed Down
    Yes, the Pre-Drilled Round Rubber Bumpers # D3-96 that you referenced can easily be trimmed down to length so that it would fit your application. After going out into the warehouse and looking at the bumper I would recommend either using a utility knife to very carefully cut it, or securing the rubber tightly and using a sawz-all to make the cut.

  • Does Rubber Trailer Bumper Require Steel Mounting Strip to Install
    The Pre-Drilled Round Rubber Trailer Bumper # D3-96 does not require a steel mounting strip in the inside to install. This bumper has pre-drilled holes and all you need to do is use 9/16" bolts to bolt it onto the rear of your trailer and you are good to go.

  • Can 96 Inch Long x 3 Inch Wide Rubber Bumper be Used With 12 Inch Bolt Spacing
    While there isn't a bumper that has 12 inch bolt hole spacing, you can still use the 96" long x 3" wide Pre-Drilled Round Rubber Trailer Bumper # D3-96. What you could do is drill the necessary holes at the spacing you need and it will work for you.

  • Recommended Rubber Trailer Bumper for 1-1/2 Inch Plate
    I spoke with Redline and although they didn't have the inside dimensions of the rubber bumper, they told me that for a 1-1/2" support you would need to use the Pre-Drilled Round Rubber Trailer Bumper part # D3-96.

  • Mounting Hardware Required for Pre-Drilled Round Rubber Trailer Bumper
    The Pre-Drilled Round Rubber Trailer Bumper # D3-96 simply requires 9/16" bolts, which can be found at any local hardware store. If you are keeping it at 96" and not cutting the bumper down to size, you will need 9 of these bolts.

  • Hardware Needed To Install The Redline Pre-Drilled Round Rubber Trailer Bumper
    Due to the wide variety of applications the Pre-Drilled Round Rubber Trailer Bumper # D3-96 does not come with any mounting hardware. You'll want to use a 9/16" bolt but will need to determine the length of the bolt based on the thickness of the trailer wall you're mounting to.

  • How to Install Redline Pre-Drilled Round Rubber Bumper # D2-96
    The Redline Pre-Drilled Round Rubber Bumper # D2-96 can be installed in a variety of ways depending on the nature of the trailer. The holes are drilled all the way through to allow user-supplied hardware to mount it. We also offer a larger size bumper # D3-96 that measures 3-inches x 3-inches. No special tool is required for installation; you will use whatever tool is appropriate for the fasteners you choose.

  • Can Custom Holes be Drilled Into a Redline Pre-Drilled Round Rubber Bumper
    Since the Redline Pre-Drilled Round Bumpers, part # D3-96, part # D2-96, and part # D4-96, are made of rubber I see no reason why you cannot drill out mounting holes so that they are custom to your hole patterns. If you will be using the full 96 inches of the bumpers then you may want to consider drilling more mounting holes in your trailer so that the bumper has more support. I recommend drilling out holes to match the rest of the pre-drilled holes to avoid more drilling. Keep in mind...

  • Replacement for 84 Inch Bumper on Horse Trailer
    All of our bumper strips are 96" long and have the holes pre-drilled out at 11" on center, but the nice thing is these can be cut and re-drilled to accommodate your application. You just need to choose which one has the width you're looking for: 2-1/16" Width - # D2-96 3" Width - # D3-96 4" Width - # D4-96 So these will definitely work, you'll just need to do some modification to make it work.

  • How to Install Redline Round Rubber Bumper # D3-96 on Trailer With 2-Inch Thick Material
    Since the (presumably steel) material on your trailer is 2 inches thick drilling it for installation of the Redline Round Rubber Bumper # D3-96 is not a great option since this would require a lot of drilling time and extra-long hardware to install it. A better option may be to use an adhesive, one that is compatible with both the rubber bumper and the trailer surface. We offer white silicone adhesive # 0160297 but most any hardware or home improvement store will carry a range of colors,...

  • Fastener Recommendation to Attach Round Rubber Bumper D3-96
    You could use some self-tapping screws like # FA1131822 to avoid drilling holes first. If you know about where the wiring is you could position the bumper # D3-96 so as to avoid the wiring. Or another option would be to drill from the backside, if possible, so you can avoid the wiring for sure. Or another option would be some type of anchor bolt or screw but that would still require drilling.

  • Separating Brake and Turn Signals, Adding a Reverse Light, and Ramp Door Support for a Trailer
    First, trailers in the US use what is called a combined 2-wire system. The brake lights and turn signals are on the same circuit on each side. The turn signal overrides the brake light on the side blinking. In order to have separate turn signals you would need additional amber turn signals and you would need to do some rewiring. On the trailer side you would need to install a special converter, # 118158. The combined left turn/brake wire connects to the yellow input wire, right turn and...
