I need help on how to change my hallman MBC springs. i want to change from the soft one to the heavy one. can anyony help me out. thanks

 

whats up bro I just did this the other day. Take the barb at the end thats parellel with the boost controler. Its the one that doesn't conect to the wastegate. Unscrew that with your hand or if its too tight 1/2" wrench. Take the ball out, then the spring, put the heavy spring in then the ball back in and lastly finger tighten the barb back on. don't use a wrnch to put it back on cuz you will damage the o-ring.

 

just unscrew the end w/ a wrench, take out a ball and then the spring. put in the heavy spring then the ball, and tighten.
