Professional Parts Installation · La Verne, California
Quality Parts.
Precision Installation.
The final result starts before the first bolt is removed. High-quality parts fit better, finish cleaner and give our technicians a stronger foundation for a professional installation.
The Difference Starts With The Kit
Great Installation Cannot Fix A Bad Part.
One of the biggest differences between a clean, factory-like result and a frustrating install is the quality of the part itself. Low-cost kits can create extra labor through poor fitment, incomplete hardware, vague instructions, uneven mounting surfaces and inconsistent manufacturing.
Quality-Made Components
We recommend beginning with reputable, vehicle-specific parts—especially proven U.S.- and German-manufactured body and aero components when available.
- More consistent panel geometry
- Better mounting locations and hardware
- Cleaner instructions and documentation
- Less correction before final fitment
- More predictable final gaps and alignment
Fitment Problems Create Labor.
Budget imported kits are often where we see the most installation challenges. When a part does not line up correctly, the technician must spend additional time correcting what the manufacturer should have solved.
- Misaligned holes and mounting points
- Missing or incorrect hardware
- Warped fiberglass or molded components
- Trimming, drilling or adjustment requirements
- Instructions that do not match the vehicle

We can look at the kit you are considering and help you identify obvious fitment, hardware or installation concerns before your appointment.

Our Installation Process
Fitment Before Finish.
We do not treat aftermarket installation like a race against a flat-rate clock. The process is built around the vehicle, the part and the condition we actually find.
Evaluate The Vehicle & Part
We confirm application, inspect the part and review how the vehicle must be disassembled before work begins.
Dry Fit & Check Alignment
Body and aero components are checked for basic fitment before final fastening whenever the project allows it.
Install & Adjust
Parts are fitted carefully, with additional time used when hardware, access or manufacturing tolerances create challenges.
Final Fitment & Quality Control
Fasteners, gaps, alignment, wiring and visible finish are reviewed before the project is released.
How Do We Price Part Installation?
Standard Hourly Rate + Materials.
We can provide a labor estimate before the project, but final installation time varies from vehicle to vehicle and from kit to kit.
We price by the hour because aftermarket fitment is not always predictable. A flat-rate rush job can reward speed when the project actually needs patience, adjustment and quality control.
Request An Estimate →What Can Change Installation Time?
- Part quality and manufacturing tolerance
- Missing, incorrect or low-quality hardware
- Vehicle access and required disassembly
- Trimming, drilling or modification required for fitment
- Previous repairs or aftermarket modifications
- Corroded, damaged or seized factory hardware
- Electrical routing, programming or accessory integration
- Alignment, calibration or specialty services required afterward
Customer-Supplied Parts Welcome
Bring The Kit. We’ll Evaluate The Install.
We install customer-supplied components every week, but the condition and fitment quality of the part affects what is possible and how long the work takes.
- New parts should arrive complete and undamaged.
- Hardware and brackets should be included whenever the manufacturer supplies them.
- Parts that require fabrication, bodywork, paint or major correction may need separate approval and pricing.
- Unsafe, damaged or fundamentally incompatible parts may be declined.
- Additional time caused by poor fitment is billed as installation labor.

Common Questions
Before You Book Your Installation.
Aftermarket parts vary dramatically in quality and complexity. These are the questions we hear most often before a project comes into the studio.
Can I bring my own parts?
Yes. Customer-supplied parts are welcome, subject to inspection and compatibility. We recommend sending us the manufacturer, part number or product link before the appointment.
Will you install inexpensive Amazon, eBay or imported kits?
We can evaluate them, but lower-cost kits can require substantially more adjustment and labor. If a part is unsafe, damaged or fundamentally incompatible with the vehicle, we may decline the installation.
Why do you charge hourly instead of one flat installation price?
Aftermarket fitment can change once the vehicle is disassembled. Hourly labor allows us to spend the time required for alignment, correction and quality control rather than rushing the job to protect a flat-rate margin.
Can you give me an estimate before I bring the car in?
Yes. We can provide an estimate based on the vehicle, manufacturer, part number and known installation requirements. Final labor is based on actual time and materials used.
Do you install complete body kits?
Yes. We install complete body and aero kits along with individual bumpers, lips, splitters, side skirts, diffusers, spoilers, wings, carbon-fiber components and related exterior parts.
Can you install suspension and exhaust parts too?
Yes. We handle many bolt-on suspension, brake, exhaust, intake and chassis upgrades. Final acceptance depends on the vehicle, part design, condition and any specialty service required afterward.
What happens if the kit does not fit correctly?
We will stop and evaluate the issue. Minor adjustment may be possible and is billed as labor. Major fabrication, paint, bodywork or structural correction is not automatically included and would require approval before additional work.
Do you install parts on exotics and luxury vehicles?
Yes. Our team works on everything from exotic supercars and European performance cars to Teslas, trucks and daily drivers.
