Bumpstop can aluminum expanding welding plug "Bumpplug"

Billet machined 3 piece collapsible welding slug. This is designed to be installed into the steel bumpstop can to help prevent it from shrinking due to weld distortion. 

Other designs on the market are a solid piece of aluminum. Since the slug is a fixed diameter it can get stuck in the can and be difficult to remove.

This 3 piece design features  a 7" long tapered steel pin that sits in a reamed tapered hole. This taper allows the slug to be installed in the can and expanded to fit tight in the bore. Once the welding is complete and cooled the pin is knocked out and the slug collapses and will easily slide out. 

Prior to being split the slugs are machined to the following sizes: 

2.0" Bumpstop = 2.0" Slug

2.125" Bumpstop = 2.120" Slug

2.5" Bumpstop = 2.57" Slug

If you have a custom size or application that is not listed feel to contact us and we can likely make whatever you need. 

This tool is now available for rent for $125. You can purchase this and return it with supplied label within 30 days in good usable condition and we will refund you the remaining $125 of the $250 purchase price. 

If you use this service you will receive a used rental tool not a new one. 

Note: These are made to order and may have a 10 day lead-time prior to shipping
