Big Bubba exists because sometimes bigger is better. This piston-style valve is built for large-capacity supercharged and turbocharged engines, including diesels - not for low-boost daily drivers. It uses a 2.0" / 50.8mm piston with Boost-Balance technology and a positive-seal O-ring, runs cap-adjustable spring pre-load, and is offered with 7, 12, 17 and 21 InHg spring options. Australian made from billet aluminum in the Sleeper finish, with an aluminum V-band fitment.
