Bergfelt's Bumpers

The Most Popular Aftermarket Loop Bumper in the USA


Bergfelt Racing Enterprises is pleased to offer our Custom Bumpers for  kart racers.  We have been supplying bumpers since 2001.   Most of the bumpers pictured on this page are the loop style that are meant to minimize the chance of other karts climbing over  in the event of contact with the rear tires.  We can also fabricate more conventional bumpers.


Bergfelt's Bumper Jr Max kart    Bergfelt's Bumper on CRG cadet

The karts above were spotted at the 2005 R-Max Nationals.  These karts were competing in the JR Max division that requires an extended bumper.  Our bumpers fit the bill perfectly.  They fit the karts perfectly tool

 Kali bumper


Full width bumper for CRG Kali.  We consider this to be the original "symmetrical" style because the loops stick out evenly on both sides.



 Our bumpers are made from quality mild steel tubing and are MIG welded.  We use mild steel because  the bumper should bend in a hard collision.  As the bumper bends, it absorbs the shock protecting the driver and the chassis.  The bumpers are supplied unfinished, ie. they are not chrome plated or painted.  We leave that up to the customer.

offset bumper
This is an offset bumper for Mongoose dirt oval chassis We call this an original style asymmetrical
bumper because the loops stick out more on one side than the other.





Jamaican Style bumper
In November of 2005 we had a request to make a bumper for a kart racer in Jamaica.  That racer requested a bumper that was just a little different but very strong in the center.  Our new Jamaican style bumper is the result.

New for 2007 is our West Coast Option.

The West Coast Optional ends are available with eitherstandard or Jamaican style middle sections.

Add $15 to the total bumper price for the West Coast style ends.

Please note; We do not provide chrome plating service. The customer arranged for the plating on his own.



CRG UAS  Kart

The kart shown here was the 2001 and 2002 Pennsylvania Unlimited All-Stars Champion.  It is an illustration of our prototype wedge body - nerf bar - bumper package.  It features leaf blower as a supercharger and dual right rear tires. We can fabricate a bumper/body package for just about any kart but we need to have the kart on hand to do it right. A custom bumper/body package is around $400.




There are two basic methods of mounting rear kart bumpers;


1.  A special rubber bushing is inserted into the frame rails and a bolt is inserted through an eye on the bumper into the threads in the special bushing.  The bumper pictured below was made for that type of application.  This is the most common method used for sprint karts but is also employed by some oval chassis.  We highly recommend that the mounting bolt is safety wired to the kart chassis.

2.  The second method requires that there are tubes attached to the bumper that insert into the ends of the frame rails.  The frame rail and the bumper insert are cross drilled and a bolt is inserted through them to secure the bumper.  This method is often used in an attempt to keep the bumper from "binding up" the chassis or preventing it from flexing freely, but since the bolt is tight, and prevents twist, some binding of the chassis still exists.  The bumpers that we make for this type of application utilize our unique no-bind technique pictured below.


no bind pinno bind installed


Bumpers start out at only $54.00 each for the basic bumper.  This is for bumpers up to 36" over all length.  Add .75 per inch for each inch over 36".
If the bumper is for an application that requires the no bind pins add $10.00.  We can also machine no-bind bushings for sprint karts that utilize the rubber bushing mounting method.  We also supply a complete line of bumper mounting hardware.  Contact us for pricing.

Since these are custom made bumpers, of course additional loops and mounting tabs and bumper configurations can be added at an additional cost.  We can also fabricate front bumpers and nerf bars.  Call or e-mail for pricing .
We have found Rustoleum spray paint to hold up very well as an attractive finish for these bumpers.

These pictures were taken at the 2005 Vintage Kart Nationals at Fremont, Ohio.

We recently had a special order for a reproduction of an aftermarket bumper that was at one time produced for the Rupp Dart Kart and A-bone kart.  The original was made from 5/8 tubing.  Our reproduction is made from 3/4 tubing.  Producing this bumper required the fabrication of a set of patterns and jigs.  We are offering these bumpers for $69 each, and $130 for a set of front and rear bumpers. They are considerally more work to make than the loop bumpers shown above.  We do not provide chrome plating.  The customers had that done on their own.

We are willing to make reproductions of other vintage bumpers.  Please contact us for details.
