The BombProof approach
Understand first.
Build from there.
Our five stages keep recommendations grounded in what your diesel needs. We also help with brakes, suspension, starting problems, and limp-mode recovery.
Diagnostics
Understand your 5.9L Cummins 12-valve before recommending work. Describe symptoms, power loss, starting concerns, or warning lights.
Describe a symptom ↗Prevention
Review fuel quality, filtration, operating temperatures, and known service history. Preserve parts that are still doing their job.
Plan prevention ↗Restoration
Bring back dependable mechanical function. We look for the cause and related needs before choosing replacement parts.
Plan restoration ↗Maintenance
Build a documented history for the engine, transmission, driveline, brakes, and suspension. Prioritize work by condition and use.
Plan maintenance ↗Performance
Once the foundation is healthy, explore upgrades that suit your towing, daily-driving, efficiency, and longevity goals.

Bespoke builds · 5.9L Cummins 12-valve
A complete powertrain.
A plan for your chassis.
Engine, transmission, wiring and controls work together. We assess your donor, chassis and goals before selecting a build path.
Engine & donor
Discuss sourcing, documented condition, inspection, restoration and the accessories needed for the planned installation.
Transmission & driveline
Match the transmission, converter or clutch, adapters, ratios, mounting and driveline to the engine and chassis.
Wiring & controls
Plan standalone wiring, ECU/TCM integration, gauges, starting, charging, cooling and the required control systems.
Used donor packages, component availability and project acceptance are confirmed by quote. Powertrain sourcing terms · Competition project policy · Explore other custom platforms
Know your 5.9L Cummins 12-valve
Good decisions
start with context.
Original equipment, service history, and past modifications help us select the next step. We explain the reason behind every recommendation.
Know what is installed
The installed injection system and any past modifications guide the fuel-supply and restoration plan.
Manage heat as a system
A cooling upgrade starts with operating conditions and how you use the vehicle. We assess the system before recommending fluids or new hardware.
Build a useful history
Bring your mileage and available service records. We use that history to separate what is due, what needs diagnosis, and what can remain in service.
I’m not certain which engine or generation I have.
Use “Refine your year, model & engine” above, browse another generation, or ask us to identify the installed engine. Transition years, imports, and swaps can need a closer look before parts are selected.
Do I need every component in a package?
No. The package builder lets you select what you want to discuss. We then check condition, compatibility, and your goals. An upgrade, additive, fluid flush, or replacement is recommended only when there is a reason for it.
Can I buy parts only, or have them installed?
Both options are available by fitment quote. We confirm the exact part before special ordering it, then arrange shop pickup, installation by appointment, or a shipping quote when appropriate.
What about emissions or competition work?
Emissions services focus on diagnosis, cleaning, restoration, and compliant upgrades. Performance and competition inquiries are reviewed for the exact vehicle and permitted use. See our competition policy before requesting restricted-use work.
Engine / product reference: View the manufacturer’s guide ↗. Exact vehicle fitment and applicable approvals are confirmed before a quote.
