About Us
Born from Yama Vans, built for those who demand more. Bay4 is the next evolution in adventure van performance—delivering expert-installed upgrades that push the limits of what your van can do.
Who we are
At Bay4, we believe that every van has the potential to go further, ride smoother, and perform better. Specializing in professionally installed performance upgrades, we fine-tune adventure vans to handle whatever the road—or trail—throws their way.
From rugged suspension enhancements to cutting-edge lighting and off-grid power solutions, we execute every upgrade for seamless integration, reliability, and adventure-ready durability.
the same dedication,
a new chapter
Bay4 was born where Yama Vans honed its craft—a 9,000+ sq. ft., four-bay shop in Calgary, Alberta. Inside those bays, we refined some of the most capable vans out there. As demand for expert-installed upgrades grew, Bay4 became its own dedicated division, focused purely on performance.
Named after the place it all started, Bay4 exists to take adventure vans even further with upgrades that match the way you explore.
our team
Bay4 is powered by a team of skilled specialists who bring precision and expertise to every upgrade. Based in Calgary’s Manchester Industrial Area, we build and refine adventure vans to take on the toughest terrain.
Our Values
The foundation of Bay4 is built on the same principles that guide Yama Vans —attention to detail, craftsmanship, and a commitment to doing things the right way. Whether we’re building from the ground up or refining performance through upgrades, we approach every project with the same mindset.
"We just returned home from Alberta after having the ARB Compressor, the Owl B2 Pro, Owl Mini-Monster Box, and Baja Lights fog lights installed. These are all upgrades that Pat suggested during the initial build… we should have listened then, but we’re glad we have them now. Thanks again for the great service and pass our thanks on to Jaimie and the other techs!"

"Works amazing! Took Kro up some steep, loose Kootenay FSRs last weekend and the (ARB air) locker prevented any rear wheel spin and left minimal tire tracks. It definitely gives me confidence to go places I might think twice about without it."

"I was just showing off our van at a dinner party last Saturday and the topic of "how well does it drive" came up numerous times, so I proceeded to explain how important the Agile Off Road package was to us when converting our MBS. It is so much fun to drive, mainly due to the right combination of superior components that Yama has sourced, it's tried and true for big blue!"

“We’re very happy with the work Yama did enhancing our van. Whether is practical (water tanks), useful (Rolef screen), or just plain sweet (rock lights) the work they did keeps our family happy in the van as we find new things to explore”
