What We Do

Every Service, Done Right

We handle everything from a simple oil change to a full transmission rebuild. If it has an engine, we've got it covered.

Oil & Filter Changes

Conventional, synthetic, and high-mileage blends — we'll pick the right one for your engine and get you back on the road fast.

Brake Service

Pads, rotors, calipers, and fluid — your brakes are the most important safety system you have. We inspect, repair, and replace with care.

Engine Diagnostics

Check engine light on? We use professional-grade scan tools to read the code, then explain exactly what's wrong — and what it'll cost to fix.

Transmission & Drivetrain

Slipping gears, grinding shifts, or a complete rebuild — our transmission specialists diagnose the issue and get your power delivery back on track.

AC & Heating

Missouri summers are brutal and winters don't hold back. We recharge, repair, and replace your climate control so you're comfortable all year round.

Suspension & Steering

Struts, shocks, tie rods, and alignments — if your ride feels rough or pulls to one side, we'll sort it out and get you driving smooth again.

About Us

Your Neighbors Under the Hood

We opened Horsepower Proving Grounds right here on West Evergreen Street because Strafford deserved a shop that actually listens. Too many people in this area have been burned by mechanics who talk fast, charge more than they should, and leave the problem half-fixed.

That's not how we roll. We treat every vehicle like it's our own — because one of us probably drove the same make and model to work this morning. We explain what's wrong in plain English, give you a fair price before we start, and stand behind every repair we make.

Why Choose Us

Not All Repair Shops Are Created Equal

Honest Diagnostics, Every Time

We'll tell you what needs attention now and what can wait. No upselling, no fake urgency — just straight facts about your vehicle's condition.

Upfront Pricing Before We Touch Anything

You'll know the cost before we start the work. If we find something unexpected, we call you first — we never add charges without your okay.

Quality Parts, Fair Prices

We use OEM and premium aftermarket parts because cheap fixes don't last. But we also respect that you're spending your hard-earned money, so we keep costs reasonable.

We Treat You Like a Neighbor

You'll walk in and actually get greeted by name. No corporate wait times, no running around in circles — just a straightforward visit to a shop that knows you.

Local Reviews

What Strafford Drivers Say

"Brought my truck in for a strange noise and they had it figured out the same day. Explained exactly what was wrong, gave me the repair cost upfront, and had me back on the highway before dinner. Honest folks — that's rare to find."

M. Torres — Strafford, MO

"My check engine light came on right before a road trip and I was stressed. They scanned it the same morning, fixed what they could, and even gave me tips on what to watch for on the drive. Saved my trip — thank you!"

S. Jenkins — Hillcrest, MO

"I've been bringing my vehicles here for years now. They've handled everything from routine maintenance to major engine work, and I've never once felt like I was overcharged. That's why I keep coming back."
