Terry Components Battery Cables: Engineering That Starts Every Ride

When it comes to getting maximum cranking power from your battery to your starter, few names in the powersports world carry as much credibility as Terry Components. Specializing in starting system components for Harley-Davidson Big Twin and Sportster motorcycles, Terry Components has built a devoted following among riders who refuse to compromise on electrical reliability. Their battery cables represent one of the clearest expressions of that engineering philosophy — products designed not just to meet the factory standard, but to surpass it.

Super Flexible Construction Built for Real-World Demands

At the heart of Terry Components' battery cable lineup is their proprietary multi-strand copper core. These cables are made from 1,650 strands of 44-gauge super flexible tinned copper wire, covered with an equally flexible black silicone jacket. The result is a cable that resists cracking, kinking, and heat degradation — all common failure points on standard OEM cables. They are designed to deliver all available amperage from your battery to the starter without voltage drop.

Terry Components also offers their premium Mega Cable line, which pushes strand count even further. These 1,666-strand Super Flexible Battery Cables are engineered to exceed all OEM standards. The unique terminal design and construction provides positive connections for trouble-free installation and dependable service.

Mega-Lugs: Where the Connection Is Made

A battery cable is only as good as its terminal connections, and this is where Terry Components truly differentiates itself. Their Mega-Lugs have at least twice as much copper weight as standard lugs, are manufactured of 99% pure electrolytic copper, and are 24k gold plated for greater conductivity. They are the heaviest starter ground lugs in the industry and will deliver more cranking power with less voltage drop than any other battery cable. For riders who have experienced hard-starts or voltage drop under load, this level of terminal engineering makes a noticeable real-world difference.

Complete Kits and Custom Wiring Solutions

Terry Components understands that not every installation is the same. Their product range spans both model-specific cable kits and individual cables for custom applications. Complete battery cable kits are available for a wide range of model years, including fitments such as the '84–'88 Softail and '65–'79 FLH. For those doing custom electrical work, auxiliary-wire cables are designed to eliminate stacking cables on the battery and are perfect for wiring directly to the terminal block, regulator, or any accessory. These cables feature 18K gold-plated and tinned copper 1,666-strand Mega Cable construction.

Whether you are restoring a classic FLH to factory-spec or wiring a custom build from scratch, Terry Components offers the right cable for the job — in individual lengths ranging from 5 inches to 32 inches or as complete application-specific kits.
