Our story
About J & J Performance & Auto
J & J Performance & Auto is Jeff's shop, first on I Avenue and now on Smoke Tree Street in Hesperia. Customers who have followed him for years know the drill: a thorough, honest look at the vehicle and a straight answer about what actually needs fixing.
We work on daily drivers and race cars alike. Jeff has built a fully tuned LS-V engine with nitrous and dyno tuning for a customer's project, and he handles everyday repairs like air conditioning diagnostics with that same care.
Customers have trusted us with their vehicles for over nine years because we only repair what's actually broken. That kind of honesty is why people keep coming back, even when the wait for Jeff's attention takes a little patience.
- Honest, no upsell diagnosis
- Performance builds and dyno tuning
- Trusted by repeat customers for 9+ years
- All makes and models welcome
