ASE certified technicians with 20+ years of experience — from oil changes to full engine and transmission replacements.
We offer a full range of auto repair and performance services. Note: we do not perform vehicle inspections or wheel alignments.
Professional OBD-II diagnostics to identify exactly what's wrong, followed by expert repairs performed by ASE certified technicians with 20+ years of experience. We don't guess — we know.
Full engine removal and replacement — remanufactured, rebuilt, or used. We've done hundreds of swaps across all makes and models. Our precision means a clean install and a vehicle that runs like new.
Manual and automatic transmission repairs and replacements. Slipping gears, hard shifts, or complete failure — we diagnose accurately and fix it right with quality-sourced units and expert installation.
Complete brake system service including pad and shoe replacement, rotor resurfacing or replacement, caliper service, and brake line repairs. Your stopping power is your safety — we don't cut corners.
Strut and shock replacement, control arm service, sway bar links, bushings, and complete suspension overhaul. Rough rides, clunking over bumps, or uneven tire wear are all signs we can address.
Radiator repair and replacement, thermostat service, water pump replacement, coolant flush, and hose inspection. Overheating is one of the fastest ways to destroy an engine — we keep yours running cool.
AC system diagnostics, refrigerant recharge, compressor replacement, condenser and evaporator service, and heater core repair. Missouri summers and winters demand a working climate system.
Advanced electrical system diagnostics for check engine lights, battery and charging issues, starter and alternator failures, wiring problems, and more. We find the root cause, not just the symptom.
Exhaust system inspection, muffler replacement, catalytic converter service, and exhaust pipe repairs. Rattling, loud exhaust, or failed emissions are all issues our technicians handle efficiently.
Fuel pump replacement, fuel injector cleaning and replacement, fuel line repair, and fuel filter service. Proper fuel delivery is critical to performance and efficiency — we keep your system clean and functional.
Regular oil changes with quality conventional, synthetic blend, or full synthetic oil. Plus fluid checks, filter replacements, and a thorough inspection to catch issues before they become expensive repairs.
Timing belt and timing chain replacement is one of the most critical maintenance items on any vehicle. Miss it and the consequences are catastrophic. We follow manufacturer specs precisely for every job.
