Custom Rear Bumper

I wanted a rear bumper that met the following requirements:
1. Tough, had to withstand hard trail use while protecting the sides and rear of the 4Runner.
2. Small, I wanted to maximize rear departure angle as much as possible, meaning the bumper should hang down as little as possible and project out rearwards as little as possible.
3. Adaptable. I wanted it to have one or more integrated hitch receiver tubes for various uses. Side receivers to allow for use of a HiL:ift jack, or to install tow shackles for vehicle recovery, etc. A center receiver for towing or installing various receiver accessories like bike racks, etc.
4. Allow for future expansion. I wanted to be able to add a full width rear swingout tire carrier and additional side and corner protection. These features are currently in design and more information will be available shortly.

Materials

2-1/2" sqaure tubing, 0.250" wall thickness, brackets are 1/4" steel plate. By using 2-1/2" tubing, which is the same size as hitch receiver tubing, the bumper profile is only as large as needed to accomodate the receiver. The mounting system is designed to allow for various degrees of body lift from stock to 3".


Installation

Installation is very easy, frame brackets bolt into the existing facotry tow bar brackets, then the bumper attaches to the frame brackets and finally the side pieces bolt to the frame and main bumper. One person install, no special tools required.

Modification to the vehicle is minimal, strictly bolt-on to existing facotry holes. The plastic "bumperettes" should be removed, and a small notch may need to be cut for the spare tire winch crank to be used.

Durability

The bumper is very tough, it has withstood several years of trail abuse. Increased departure angle substantially over stock and the clean design helps eliminate getting hung up on the bumper.
