Much needed part for my truck.
Quick ship and perfect fit.
Thanks again eTrailer !
Just what I needed..
Shipping was very fast!
They arrived quickly, and they actually fit in the tube ends. I might be ordering two more to replace the old ones, should they pop off along the way. VERY glad I went with you guys on these end caps. Very satisfied with my purchase.
After going to the Toyota dealership and being told that this product for my vehicle was no longer available, I turned to the internet and found your site. You had what I needed, great price and quick delivery. The product fit perfect and I am very satisfied. Thank you
Product was exactly as advertised, came quickly, and fit like a glove. etrailer.com delivered on time and on budget!

The original end cap was lost somewhere and the replacement fit perfectly. It is still in place on the bumper.

Very good product and a very good company to do business with.

Thanks for keeping me updated on the order. The pkg came and was exactly as described. Would recommend 100% to others to order from etrailer.
The end caps were exactly what I needed. Made strong and looks great on my truck. The order came very fast no problems in ordering or shipping . I would recommend this product and company for what you need.
This is what I needed to replace the old and missing caps etrailer was the only place I could find them and etrailer shipped them quickly and I must say that their web site was great easy to find what I was looking for
Thank you etrailer
Product arrived exactly as described and was a perfect fit. Fast shipping and excellent customer service. Would definitely recommend buying from this seller! Thanks again!
Fits the round ends of my Tech Tubes Nerf bars perfectly. Pleasant surprise since I could find very little about Tech Tubes. And a great price.
Product was received on time and was as described!! The caps fit my 3" nerf bars perfectly with no issues and actually fit better than the originals. The fit is a little tighter so you will be less prone to losing the caps over time. It may be a bold statement but this are sort of universal and may fit most 3" bar applications as I took a chance and was very happy with the outcome.
Kindest Regards,
I was thrilled to be able to find this and at such a great price. The transaction was simple and the shipping was quick. I would buy from etrailer again in a minute. Thank you!
Got these for my Luverne 3 inch Nerf Bars. Even though they are for Westin Nerf Bars, these caps fit perfectly. Ordering and shipping was easy and fast!
Perfect fit and excellent delivery time!
The replacement plugs were shipped very quickly, fit perfectly, and look great. The price was very fair and I am totally satisfied with my shopping experience with etrailer.com. I'll be comming back for replacement parts for my boat trailer. Thanks.
These caps were ordered for my 2003 Tacoma with factory Nerf bars. These 3 inch caps made for Weston Nerf bars fit perfectly. Very nice product and quick shipping. My 1st experience with etrailer.com was a great one. Thanks!

I have a pair of Manik side rails and while going through a car wash recently lost one of the end caps off the side rail.
After measuring the other side rail caps these were a perfect fit, so I ordered two for replacement purposes.
Excellent fit and replace even thiughntheynwere not rounded caps (bulb type)
Will use etrailer again as this is my go to store for most of my pickup truck parts.

Still the same and have not moved since the first install. Have recommended to fellow pick up buddies as they also had problems with their end caps missing.
The front of my tube steps were rusted beyond repair so I cut off the front section before step pad and inserted new endcap, looks good
The replacement end cap for our Westin Platinum Series step fit perfectly. I especially appreciate the exact measurements posted on your website, enabling me to order the part with confidence. Thank you for the prompt shipment and follow-up emails after I placed my order. Impressive customer service!
