Custom Solutions

Service Scope

We specialize in solving mechanical problems where off-the-shelf parts are either insufficient or non-existent, bridging the gap between a repair shop and an engineering firm.

• Welding & Structural Fabrication: Custom mounts, brackets, and housing reinforcements designed for high-stress environments.

• Axle Trussing & Strengthening: Structural reinforcement of axle housings to prevent bending or failure in heavy-duty or off-road applications.

• Performance Re-gearing: Custom ring and pinion installations to optimize torque and power delivery for specific tire sizes or tow loads.

• Driveline Modifications: Component adaptation and driveline shortening or lengthening for non-standard equipment configurations.

• Obsolete Component Restoration: Recreating or repairing discontinued parts for legacy industrial and agricultural machinery.

• System Adaptations: Custom PTO and power transmission setups for specialized vocational equipment.

Common Use Cases

Custom solutions are typically required when equipment has been modified, discontinued, or pushed beyond its original design limitations.

• Repeated Structural Failure: Standard housings or mounts that continue to crack or bend under your specific duty cycle.

• Legacy Equipment Support: Drivetrains where the OEM no longer provides replacement parts or technical support.

• Performance Optimization: The need for custom gear ratios, lockers, or trusses for high-performance off-road or towing builds.

• Mismatched Components: Integrating modern drivetrain components into older frames or industrial systems.

• Extreme Operating Conditions: Equipment requiring specialized hardening to survive in high-vibration or high-impact environments.

Our Process

Every custom project begins with a forensic assessment of load requirements and environmental stress to ensure the final build is fit for purpose.

• Application Assessment: Evaluating the mechanical constraints and performance goals of the specific project.

• Engineering & Design: Planning the structural modifications, material selection, and drivetrain integration.

• Precision Fabrication: Executing custom welding, machining, and component adaptation in our Jacksonville facility.

• Alignment & Assembly: Ensuring that custom-fabricated parts maintain perfect mechanical geometry with existing drivetrain systems.

• Validation Testing: Verifying structural integrity and load-bearing capacity under real-world operating conditions.

Why Us?

We focus on long-term durability and mechanical logic, providing solutions that prioritize functionality over temporary fixes.

• Cross-Discipline Expertise: A unique combination of master-level drivetrain knowledge and professional fabrication skills.

• Problem-Solving Mindset: We specialize in the "unrepairable" jobs that other shops turn away.

• Industrial-Grade Standards: Our custom work is built to withstand the same rigors as the Class 8 and construction equipment we service daily.

• Innovation Where Parts Don’t Exist: The capability to design and build one-off solutions for obsolete or specialized machinery.

• Focus on Reliability: Every weld and gear set is executed with a focus on reducing future maintenance cycles.

Frequently Asked Questions

Technical answers regarding custom fabrication, axle strengthening, and performance drivetrain modifications.

• What is axle trussing and do I need it? Trussing involves welding structural reinforcement to the axle housing to prevent it from bending under heavy loads or off-road use. If you are running oversized tires or heavy equipment, it is essential insurance.

• Can you repair a gearbox if the manufacturer is out of business? Yes, we specialize in "obsolete restoration," where we repair or adapt components for legacy industrial systems.

• Do you offer custom welding for aluminum housings? We provide professional-grade welding and fabrication for various metals, tailored to the specific needs of the drivetrain component.

• Can you change my gear ratio for better towing? Absolutely. We can help you select and install a ring and pinion set that optimizes your torque curve for heavy hauling.

• What is a "one-off" build? This refers to a completely custom mechanical solution designed specifically for your unique equipment or application.

• Can you modify a driveline for a custom engine swap? Yes, we handle the component adaptation and alignment required to integrate mismatched drivetrain parts.

• Do you work on performance 4x4s? We provide a range of performance services including lockers, custom gearing, and structural hardening for off-road vehicles.

• How do you ensure a custom part won't fail? We evaluate the load requirements and use over-engineered materials and precision welding techniques to ensure the part exceeds its expected stress levels.

• Do you provide drawings or specs for your custom work? We provide documented build summaries for custom projects so you have a record of the modifications made.

• Can I bring in a sketch of a part I need made? Yes, we can work from your designs or help you engineer a solution from scratch based on the mechanical problem you are trying to solve.
