Bump-er (bum'per) n. 1. One that bumps. 2. a. either of two metal Structures, typically horizontal bars, attached to the front and rear of a Car to absorb the impact of a collision. b. A protective device used to absorb shocks. Well now that we know what they are why do we need them? Well there are numerous reasons we want bumpers. Everything from protecting the fragile sheet metal during minor parking lot mishaps, to helping save lives in serious accidents. Than there are the extreme uses. Situations including off roading adventures, to heavy duty rescue/recovery operations for professionals. The bumpers we are going to be looking at are of the off-road application. One of the best hand made bumpers I have found produced that will fit on any application is from Kennesaw Mountain Accessories (KMA).These bumpers are rugged, sturdy, unyielding & forever unforgiving. Made out of 1/4" structural steel, either being tubing, or plate steel, these bumpers have what you are looking for. With options to include: Turn Signals, Tire Carriers, High lift Mounts, Winch Mounting to Recovery Points (D-rings) these bumpers offer it all. KMA also offers bumpers for most applications.
I placed my order for a Wincher & Multi carrier for my 88K5 Blazer, and was given a approximate ship time of 4 weeks. Kyle was happy to offer a "custom" setup on my front bumper to include details to give it the look of a Bull Bar.
Kyle informed me that they "Should" be cutting my bumpers the following week. That would put them over the 4weeks they quoted me upon ordering my bumpers. On the 6th week I called Kyle, inquired on the status of my bumpers, same deal. They were working on them and they should be finished shortly. Well I'm sorry to say, it took approximately 12weeks to receive both of my bumpers from KMA. I will say one thing, even though I was getting pretty impatient, their product was certainly worth the wait. I have since used them quite extensively during recovery operations on my truck and friends vehicles with out a single failure, or problem related to the bumpers operation. Installation: Installation of KMA's products is pretty straightforward. After receiving your bumper(s) you should unwrap your bumper, inspect for any significant damage, check for all the proper mounting hardware and check for rough fitment on your vehicle. When checking for fitment, especially for the Wincher, you want to make sure that when you mount the bumper, the winch will not be in the way of proper airflow into the radiator, check for anything that that may prevent you from installing your winch in the location that you want.
If you don't have the winch of your dreams when you are planning on installing your bumper, either check the manufactures website, or call their technical support number and get the dimensions for the product you are planning on buying. This was especially important in my application. The winch I was planning on purchasing wasn't even officially released to the public yet. I did have a semi-hard time obtaining information regarding dimensions for the HS9500i. When you are prepared to install your front bumper, either get a few friends to help you. At 75lbs, my bumper was a interesting self-install. What I did was used my floor jack with a 2x4 that had been made into a "t". This was originally used for installing a Energy Suspension Poly Kit on my 88K5 Blazer. But worked flawlessly in this application. I manipulated the bumper into the rough position using the floor jack & 2x4 "T".
Another thing to consider is that there is usually a bit of frame/body flex when fourwheeling. Make sure the bumper will not obstruct the body when it's moving. (Read: DAMAGE). To achieve the look/position I wanted for my truck, I ended up altering the frame rails of my truck.
I decided to drill the holes with the bumper on the truck. This way the holes would be in the exact location I wanted them in. This also would prevent any of the holes from shifting and causing a alignment problem during installation. After you get at least 2 of the holes drilled (one each side). I suggest you use 2 of the bolts and mount the bumper. You can than continue with the other 4 holes to finish securing the bumper to the truck. After finishing with the other 4 holes, insert & tighten the last 4 bolts, remove all the hardware you were using to help hold the bumper in position while drilling,, stand back and enjoy! You should now have your front bumper in the exact location, & position that you were planning. You may want to take this time to double check for any clearance issues. Special Notes for: Front Bumper. If you order the turn signals in your KMA Wincher, there are no grommets to protect the wires coming through the bumper. One option is to purchase a foot of fuel line, cut in half and slice it down the side, insert the wires into the fuel line, and slide the line into the bumper. This would provide protection from the metal. Because the turn signals are the furthest item from center, if you wrap your winch cable around your bumper during recovery periods for ease in loading, you will end up tearing the wires from something. One option is to purchase some bolts from a local hardware store, and either drilling and tapping holes to thread them into, or weld the head to the back of the bumper. (threads going towards the body) This way, if you do wrap the wire around the bumper, they will catch on the bolts, not the wires for the turn signals. Your bumper may not come with drain holes. If you don't have turn signals, this isn't a problem. But with my bumper having turn signals, my bumper filled up with water pretty quickly. All you have to do is drill holes in the lowest point in your bumper. This will allow any water to drain out. Special Notes for: Rear Bumper. One of the problems I ran into with the rear bumper on my truck is. I have wires running through my chassis at the furthest most rear point of my chassis for: Fuel Pump/gauge, and lights. There were no provisions made in the bumper to continue to allow these to go where they needed to. Before installing your rear bumper. Unplug the wires, and remove them from any area they may end up being pinched when installing the new rear bumper. After placing your bumper in the location you want, make sure the tailgate will not strike the bumper when its lowered & has weight upon it. In my application I did some grinding to help provide clearance so the bumper could be lowered without hitting the bumper. This helped to give me more of a departure angle, but still allowed me to place the bumper nearly where I wanted it. A safety issue- A idea I had was putting a "door pin" switch on the swing-away carrier to know if the tire carrier wasn't secured. You never know if a individual may come by, mess with it, and than when your driving, it could swing open and strike your truck or worse, another individual.
Your rear bumper may not come with a drain hole. After few days of rain my rear bumper filled up with water pretty quickly. All you have to do is drill a hole in your bumper. This will allow any water to drain out. KMA offers bumpers for many vehicles. Call for your application.
