Expanding Bump Stop Can Aluminum Welding Plug

Frank's Fab & Machine Exclusive!

"The Bump Plug" is a billet aluminum machined 3 piece collapsible welding slug. This is designed to be installed into the steel bump stop can to help prevent it from shrinking due to weld distortion. 

Unlike other solid designs on the market are a . Since the slug is a fixed diameter it can get stuck in the can or 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. The aluminum plug acts as a heatsink, pulling heat away from the weld as well as a support to help prevent shrinkage. 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
