What Our Clients Are Saying

  • Much Needed Product

    "Yes, I have. As a former driver, I would say this is an excellent, much needed product. Much obliged."
    -John Taratuta

  • Your Shim is a perfect fit!

    “Thanks for inventing The Shim! I have two of them. One is tied to the pig tail. I use it all the time with our older trailers. Now I don’t have to put small sticks in to hold them in place. Your Shim is a perfect fit!”
    – Glen Bolding

  • This product saved me time and money!

    “Today in Kentucky, another driver radioed that my brake lights had stopped working. Put the Sure Shim on and my brake lights started working again! Without a doubt this product saved me time and money today!!”
    – Greg B.

  • I know my trailer pigtail is secure

    “Thanks to sure shim I now know that my trailer pigtail is secure. Can’t count how many time’s ice had issues with a loose plug and having to wedge something in there to hold it in and keep my lights working thanks sure shim”
    – Paul H.”

  • I can honestly recommend this product

    "Craig Davies sent me a few Sure Shims so I could try.  I wasn’t sure what to think about the product as we’ve always seem to have loose or worn plugs when we pick up several trailers within a month, but I can honestly say after trying Sure Shim that problem has been solved;  no more flashing tail lights, no more directionals that work on occasion; it was a quick fix. I can honestly recommend this product”
    – Roy R.

  • Extremely Durable

    “Craig Davies gave me a couple Sure Shims to try out last summer. Not only do they do everything as advertised, they seem to be extremely durable. They come in a package of 2 and I’m still using the first one after 6 months of continuous use in the harshest of conditions.”
    – James H.

  • Use shim faithfully

    “No wear, whatsoever, in my plug and/or receptacle…use shim faithfully.

  • Every driver should keep these in their toolbox

    “Gone are the days of utilizing whatever you can find to jam in the plug. This product is easy to use and is a sure fit to ball types of pigtails. I have told so many people about this lifesaver, I have gotten several businesses to look into, and ordering this to keep in stock. I have given drivers my shims to solve their problems of lights not staying on! In fact, I just gave my only one away to help a driver yesterday! I always carry a can of electronic cleaner, and sureshims, and have never had to get back out of truck because of lights going out, this product works very well! I do mostly drop and hooks, so I never know the condition of the female pigtail plug, and sure shims has taken care of many situations where a connection was a problem! Every driver should keep these in their toolbox, they are definitely a must have!”

    – Kenny Dean Wheeler

  • You absolutely need at least a few of these anytime you’re in a truck

    "I'm a transport driver for Pepsi cola and have been for 32 years. For 31 1/2 of those years when the lights on the trailer would flicker or not work at all I would search for a broken piece of pallet or stick or screwdriver, whatever I could shove into the connection at the pigtail. Sometimes it worked sometimes it didn't.
    A few months ago another driver gave me a Sureshim. Since that day I  use the Sureshim almost every day! It's a great product and does a much better job than a broken piece of pallet.
    I've been using the same one that was given to me 6 or 7 months later.
    Today I brought 4 more! I should be set for the next few years!
    A huge Thanks to the folks that came up with this AWESOME product!!"
    -Kirk G. Brown Jr.

  • No More Flickering

    "No more flickering or failing light with sure shim they keep the plug and pigtail tight I swear by them when changing trailers on a constant." - David Z.

  • Sure Shim is a great product

    "Sure Shim is a great product, it eliminates poor connection problems, and it protects the male-female connection pieces."

    - Lon Child

  • 100% Worth It

    "We purchased 30 of these for a trial period with our CMVO's and we received wonderful reviews from those drivers. After the great results from the trial period I have ordered 200 more for the entire fleet of 140 CMVO's. I definitely recommend!  I shared the success we had with the sure shim and the majority of our terminals in other states have ordered for the entire terminal fleets of CMVO's."
