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

 


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.





This is our original prototype bumper that was made for a CRG Heron Oval chassis






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.





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.

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.
