What Is the Driveline — and Why Does It Matter?

The driveline is the collection of components that transmits power from a vehicle's transmission to its drive wheels. Every rotation of the engine that actually moves a vehicle passes through the driveline — making it one of the most mechanically demanding systems on any car, truck, or powersports machine. Driveshafts, axles, flywheels, ring gears, bellhousings, clutch hardware, and the fasteners and tools that service them all fall under this broad umbrella. Whether you're building a high-horsepower street machine, prepping a race car, maintaining a daily driver, or servicing a UTV, driveline integrity is non-negotiable.

Driveline Components & Subcategories

This category spans a range of parts and service tools. The core Driveline subcategory covers rotating assemblies like driveshafts and axles — the backbone of power delivery. Removing stubborn rotating components often requires dedicated pullers: the Flywheel Puller subcategory covers tools engineered specifically to safely extract flywheels without damaging the crankshaft, while Gear Pullers tackle gears, bearings, and other pressed-on driveline components. For shops and track crews that need quick wheel changes, a Wheel Chock Quick Release Kit keeps things efficient and safe. Precision installations also call for proper alignment — that's where a Drive Shaft Centering Tool becomes essential for ensuring vibration-free assembly.

Top Brands in Driveline

ARP (Automotive Racing Products) is the undisputed standard-bearer for driveline fasteners. Their product line covers virtually every critical fastening point in an engine and driveline, from flywheel bolt kits and ring gear hardware to bellhousing and carrier fasteners. ARP's chromoly fasteners are used by championship-winning teams across NASCAR, IndyCar, Formula 1, and NHRA, making them equally trusted in street builds and professional racing.

DSS Racing (The Driveshaft Shop) has spent over 30 years engineering innovative drivetrain solutions for Sport Compact, European, and Modern Muscle platforms. Their 1-piece aluminum and carbon fiber driveshafts are precision-built and dynamically balanced at over 9,000 RPM, with axle ratings reaching up to 2,000 HP — covering everything from a weekend track car to an all-out drag build.

OTC Tools brings a century of tool-making expertise to driveline service. Founded in 1925, OTC actually pioneered the universal gear puller — a tool so well-designed it remains nearly unchanged today. Their driveline and drivetrain tool lineup includes flywheel pullers, gear pullers, and specialty service tools trusted by professional technicians worldwide.

EPI is a respected name in powersports driveline, specializing in performance clutch kits, belts, and related components for UTVs and ATVs. EPI products are engineered to handle the torque demands of off-road and work applications where stock driveline parts often fall short.

Tiger Tool rounds out the lineup with heavy-duty specialty pullers and driveline service tools built for commercial and industrial use. Their tools are designed for demanding professional environments where durability and leverage are critical.

What to Consider When Shopping Driveline

• Application: Street, strip, off-road, and powersports each have different driveline demands — match the part or tool to your specific use case.
• Material: Aluminum and carbon fiber driveshafts reduce rotating mass for performance gains; steel remains the workhorse for heavy-duty durability.
• Fastener grade: Driveline fasteners must withstand sustained torque and vibration — never substitute standard hardware where high-strength fasteners are specified.
• Tooling: Many driveline service jobs require dedicated pullers or centering tools; using the wrong tool risks damage to precision components.
