We inspect, service, and repair trailer axles and suspension systems to guarantee smooth, stable handling under heavy loads.

We repair 4-pin, 6-pin, and 7-pin connectors, install protective conduit, and upgrade older systems to high-visibility LED lighting. We make sure your trailer remains visible, reliable, and completely road-legal in all driving conditions.

"I was trailering my boat from Vancouver Island up to Vanderhoof to sell And had a wheel bearing explode and Damage the spindle, We limped into a gas station in Williams Lake around 2 AM and called in to the shop at 7 AM and within five minutes one of their employees came to us assess the situation and had us follow him slowly back to their shop where they had four guys work nonstop to get the issue resolved and me back on the road as soon as possible. I don’t often write reviews, but when I’m stranded and needed a hand, these guys definitely helped me out and I would highly recommend.
