4th Gen 4Runner Low Profile Rear Bumper Kit

From: $720.46

This is a high clearance DIY weld-together bumper kit for the 4th generation (2003-2009) Toyota 4Runner. With the 4th gen 4Runner, Toyota left a lot to be desired when it comes to fitting a clean, high clearance rear bumper. The stock bumper extends way up the sides of the body and there is a bulky frame crossmember located behind the rear lift gate. Both of these factors make it very difficult to maximize ground clearance and maintain a low bumper profile. After many design iterations, we settled on a bumper that leaves your frame crossmember fully intact and keeps the top 6" of the stock plastic bumper valence. By doing this, we feel that we have achieved a very tidy bumper profile that will complement the lines of your 4Runner. This also means that no frame modification of any kind is required. This bumper allows you to forget about departure angle and substantially improves the offroad capability of your 4th gen 4Runner. It offers excellent protection from trail obstacles and distracted drivers alike and has been kept to a weight of 130lbs through careful design work.

Description

The profile of this bumper has been designed with maximum ground clearance and departure angles put first. The bumper sits as high and tight to the rear frame crossmember of the 4th generation (2003-2009) Toyota 4Runner as possible, while the angled side wing faces will smoothly slide over obstacles and ensure you do not get hung up on the trail. The side wings of this bumper provide un-interrupted plate protection that wraps underneath the vehicle and into the vehicle frame. These side wings will take a serious hit without flexing or deflecting into the vehicle body. We know that many Toyota 4Runner owners want to run oversized tires, which often create interference and rubbing issues with the stock bumper. We have thought ahead and specifically designed these bumper side wings to clear 35″ tires.

The main section of this bumper is CNC-bent out of a single piece of  3/16″ P&O Steel. This greatly reduces the amount of welding and grinding required by you and makes for a cleaner finished product. If you are paying to have the bumper assembled by a welding shop, this significantly lowers the cost.

We finished this bumper off with optional single and dual swing out carriers, a high clearance hitch receiver, LED pod lights (custom cut outs available by request), and heavy duty 9/16″ recovery points that are placed directly in line with the Toyota 4Runner frame to eliminate any leveraging effects. These recovery points are formed out of laser cut steel plates that pass through the bumper shell and tie directly into the bumper’s main mounting points on the 4th gen 4Runner frame. The recovery points then get welded to the in and outside of the bumper shell. These factors all combine to form recovery points that minimize stress on your 4th gen 4Runner frame and provide reliable recoveries of heavily loaded vehicles in the worst of offroad situations. What could make this bumper even better? The low profile design has resulted in very reasonable weights of 130lbs for the steel bumper and 64lbs for the aluminum version. Considering that this bumper replaces your factory bumper, hitch receiver and associated components, the resulting weight increase to your 4th gen 4Runner is surprisingly minimal. This reduces added stress on your vehicle, maintains precious payload capacity, and allows you to keep your factory suspension if desired.

The swing out tire carrier comes in either a single or dual sided configuration and is built to accept a tire up to 37″ in diameter! Both carriers include mounting brackets for a hilift jack and other recovery items. The dual swing out includes the hilift mount as well as a lockable jerry can holder designed to fit two 20L NATO style jerry cans. These carriers feature heavy duty chromoly heim joint hinges, 2000lb toggle latches, T-handle spring pins, and a replaceable UHMW catch pad that provides secure, rattle free operation. The heim joints in conjunction with the toggle latch provide tons of adjustability, allowing for easy assembly and guaranteed alignment of the carrier latch. The single swing out add-on weighs 34lbs and the dual swing out add-on with gas can holder weighs 77lbs.

•DIY Weld-together kit – This bumper arrives as precision CNC-laser cut and bent pieces that you then weld together (detailed assembly instructions included)

•CNC-bent plates greatly reduces amount of welding and grinding required by you and makes for a cleaner finished product

• Slim profile is engineered to provide maximum ground clearance and complement the factory body lines – trimming of stock plastic bumper required

• Heavy duty 3/16″ plate steel construction for maximum offroad strength and durability

• Optional 1/4″ 5052 aluminum construction for a lightweight yet very durable overlanding setup (66lb weight savings)

•Optional 2″ hitch receiver is tapered for a clean look and further clearance gains (While the hitch is very well reinforced, we cannot rate it for on-road towing due to the DIY welding nature of this kit)

• Mounts directly to frame using 14 factory mounting points – no drilling required.

•Reinforced 9/16″ thick clevis mounts allow the use of 3/4″ D-Rings and pull directly off of the frame for confident recoveries of heavily loaded vehicles

•All kits ship as clean, bare metal that is ready to weld out of the box – the Nitrogen laser cutting technology means no cutting edge oxidation and thus easier and stronger welds

•Optional Single and Dual Swing out carriers with spare tire mount, hilift jack mount and locking dual NATO can holder (dual swing out only)

LED Light Option: The updated version of this bumper is sleeker and lower profile at the corners and can no longer fit the optional lights inside the bumper. Instead, the LED light option includes adjustable CNC laser cut tabs to mount the lights either on the swing outs or on top of the bumper.

Bumper assembly

As for welding, with everything designed using CAD software and then CNC laser-cut to size, the pieces fit together perfectly and this makes for a very simple assembly process. All kits come with detailed instructions with plenty of clearly labelled diagrams that are made using cutting-edge CAD software. This bumper kit is well within the ability of a novice welder and many customers have purchased it as their very first welding project with great results! This is made possible by the clean parts fit-ups and thick material. These are two factors that make welding significantly easier. Welding is one of those skills that is easier to learn than you may think and once you can do it, you’ll wonder how you ever got by without it. Alternatively, many individuals buy the kits and then have a local welder assemble it for them. Even in this case, it typically ends up being less expensive than buying a pre-fabricated bumper – especially after considering the lower shipping costs of our kits vs. fully assembled bumpers.

(The 4th gen 4runner is shown, but the build process is nearly identical to this bumper).
