Shop Quality

Hydraulic Crimp + Seal

Every cable is crimped and finished for durability, conductivity, and long-term reliability.

How Ordering Works

Step 1

Bring Specs

Share cable length, wire gauge, terminal hole size, and any heat-shrink color preference.

Step 2

We Build It

We cut, crimp, and seal the cable using hydraulic tooling and marine-grade heat shrink.

Step 3

Install With Confidence

Take home a cable that fits the first time and is ready for high-current use in the real world.

What Makes a Great Cable

We build cables with the materials and methods that hold up to vibration, weather, and high-current use.

Pure Copper Conductors

High-quality copper and welding cable options for dependable current delivery.

Proper Terminal Lugs

Pure copper and tinned copper lug options chosen for fit, corrosion resistance, and lifespan.

15-Ton Hydraulic Crimp

Cold-weld style crimping creates a tight mechanical and electrical bond at the terminal.

Marine-Grade Heat Shrink

Glue-lined 3:1 shrink seals the joint against moisture and vibration in harsh environments.

Pro Tip

Bring your old cable if possible

Using the old cable as a template speeds up build time and helps avoid fitment issues.
