About
Diesel owners across Walnut Creek and the East Bay turn to Devil Mountain Diesel for diesel engine repair and truck service that keeps heavy-duty and lifted trucks running right. We specialize in diagnosing and repairing the electronics and suspension systems that dealers often struggle to resolve, including stubborn fault codes on modern pickups.
Our team installs performance and off-road upgrades, from exhaust and engine accessories to complete suspension builds, with careful attention to how each part fits your truck. We also tackle full mechanical overhauls on older vans and 4x4s, sorting out steering, brakes, cooling, and transfer case issues so the whole vehicle performs reliably.
Customers appreciate that we explain what we find, work efficiently, and keep our pricing fair.
Visit our shop or call to talk through your diesel or truck project, and we'll give you a clear plan before any work begins.
