I have an older bmx (2006) that has one piece cranks that i would like to change to 3 piece cranks but the bottom bracket shell is bigger than usual does anyone know if this is possible?

You will need to find an american bottom bracket that matches the spindle size of your crank

I put a mission bb in a Hoffman dirt merchant frame a few years ago with Redline flight cranks. It was an easy install and worked great. The bb was basically just mid bearings with cups to adapt to the american shell size. You can get different size bearing ID's to match the spindle size you want to use. Mission also makes the cups separate if you want to use a different mid BB. Link below to the kit I used on Albes.
