Bates Rear Bumper/Tire Carrier Design (Commercially
Available)
Alan Bates of "Rockrover"
who designed and produced the front winch bumper and the rock sliders
for the P38 Range Rover has now come up with a commercially available
rear bumper and tire carrier. As well as being stronger than stock, the bumper is
designed to provide increased departure angles, and the option of a
swing
away tire carrier for easy access to a second spare, or a storage spot
for the main spare if you are running big tires. Hi-Lift and jerry can
mounts are also available. The bumper uses 3/16"
steel with 1/4" mounting brackets, and mounts to the existing
rear frame horns. An extra bracket secures the forward sides of the
bumper to the sides of the vehicle frame. The bumper is powdercoated a satin black, and has a 5/16" thick
6061 T6
aluminum skid plate.

The rear swing hinge
uses roller bearings and a greaseable zerk fitting. A locking
compression latch and rubber-lined striker bracket ensure rattle free
operation. A pushpin is used as a safety
backupto keep the arm in the closed position and as a stop to keep it
open in a 90 or 120
degree position. A safety stop pin keeps the arm from doing any
damage if it unintentionally swings open.
A Hi-Lift
4XRAC mount and a Con-Ferr jerry can holder can easily be unbolted if
desired. Mounting tabs on top of
the spare tire upright and Hi-Lift / Jerry Can upright can be used for
mounting a CB, GPS,
Satellite Radio antenna, etc. The
swing arm blocks the stock location
of the license plate
and cehter brake light, so a
lighted license plate holder with an LED
third brake light is mounted to the
spare tire stud.
Availability & Installation: Email
designer Alan Bates for informaiton on obtaining one of these rear
bumpers, with or without tire carrier. Alan has kindly offered to help
sponsor this site based on the referrals he receives, so please mention
you saw his products on Rangerovers.net.
Installation:
Installing the bumper involves drilling 4 holes through the frame, but
this is very easy to do. Since the bumper design is intended to incrase
the rear departure angle, you also need to unbolt the factory hitch. A
2" receiver is built into the new rear bumper for up to Class II
trailering and for a recovery loop. However, if you plan on heavy
towing, I would strongly advise
keeping the stock rear bumper and hitch set-up.
Kaymar
Rear Bumper and Tire Carrier
The photos in this section (courtesy of Ron Beckett) show two
versions of a
custom fabricated swing-away
spare tire carrier that mounts to the rear bumper. These were made
in Australia by Kaymar. Unfortunately they are not making it available
in quantity, but if enough customers contact them you never know!!
Ron Beckett recently obtained one of these for his P38A. His observations were as follows: "The strength of the bar is quite impressive but what is very important is how they have supported the rear bar and the wheel carrier. The bar bolts to the end of each of the chassis rails as is done with the OEM bumper bar. The bar also bolts to the cross member that runs under the wheel well - as per the OEM towbar. But the bar also has two long heavy pieces of right-angle metal that slide down inside the chassis rails and which are bolted both vertically and horizontally to the chassis. From the end of the bar which carries the wheel carrier pivot, there is a support stay back to the chassis - this provides some triangulated support. Also from the ends of the bar are heavy (and strong) cast alloy side plates which replicate the sides of the OEM bumper bar. These plates bolt, via bracketing, under the car to the chassis behind the rear wheel arch."

Finished rear bumper and
tow/recovery point |
The images below show Chris's 4.0 with the
stock rear bumper removed, and the work performed to provide strong
mounting points. Chris comments: "As you
can see,
I wanted something strong enough to attach a decent tow-hitch to for
recoveries. So the first
thing I did
was remove the old bumper and replace the flimsy crumple bar behind it
with a
length of box steel, welded onto the chassis rails at either
side. This
formed the base for the new bumper which I made out of mild steel so I
could
shape it easily. I also wanted a small amount of crumple in this
so if I
do hit something it will crumple before the body panels. This was
then bolted
onto the existing bumper mounts, the chassis rails and the new steel
bar. I also
wanted a towhitch
in the middle of the bumper to make it easy to hook a recovery strap
for out in the
desert. (I
don’t tow anything other than stuck cars, so I didn’t need a proper
towball or anything, just something for a snatch strap). So we bolted the tow-hitch directly hrough
the bumper to the new box section that replaced the old crumple bar".
