Rear 4Runner Polyurethane Body Mounts (Pair)

Starting at: $75.00

Many years ago back in 2002 when we built our first custom steel rear bumper attached to the frame and not the body, we found you had to gap the bumper at least 1" to prevent body flex from hitting the bumper wings. When you hit the bumper hard on a rock, you were certain to get a body ding from bumper deflection. This is was even with over 1" gaps, between the body and any part of the bumper. The bottom line is the body and frame on the 1996-2002 4Runner moves a great deal.

Years and years went by and we just dealt with the issue, making bumpers with large gaps to prevent damage, but still protect the truck. In this time I acquired a 1990 Toyota 4WD Pickup known as the "Red Truck" and featured in the Jan/Feb 2013 Issue of Toyota 4WD Owner Magazine. In Moab Utah on the Flat Iron Mesa Trail there is an optional canyon off shoot and I took my 1990 truck up it. During the climb I hit the rear winged bumper on a rock much in the manner I had done hundreds of times in my 1999 4Runner. I was certain I had deflected into the body. To my surprise, nothing what so ever happened. I wheeled that truck more and more, amazed at what it could do and the beatings it could take. At this point it puzzled me as to why this truck could take such hard hits and the 3rd gen 4Runner with the same bumper would have so much deflection.

After some investigating I found that the very back 2 mounts on the 3rd Gen 4Runner literally float in rubber and provide no support what so ever. The frame and the body do literally come together and collide. Here you can see how much a stock body mount will move upward and downward with VERY LITTLE force from our press. The solution is a solid style polyurethane body mount that will not allow the body and frame to collide with each other. We have run this mount HARD on our 2001 IFS 4Runner for over 2 years in testing and there are no negative effects only positive ones. While this is specifically designed for a custom steel frame mounted rear bumper, slamming a trailer hitch would have the same effect and this part can also be used on truck with a stock rear bumper. CNC cut steel base plates with a black polyurethane cushion. 100% bolt in and works with or without a body lift. Shipping is flat rate to anywhere in the USA.
