SMG 20" 2/0 Engine to Chassis Ground Strap Fits 2010+ Camaro and more

SMG 20” Auxiliary Ground Strap – 2/0 OFC Power Cable

If your 5th or 6th Gen Camaro, CTS-V, or other late model GM performance car is cranking slow after long tube headers or other mods… you’re not alone.

New battery didn’t fix it?
New starter didn’t fix it either?

Here’s why 👇

Over time, the undersized OEM ground cable degrades from heat, resistance, and corrosion. Add headers (more heat), higher compression, or increased cylinder pressure—and now your factory ground simply can’t pass the amperage your starter demands. The result? Slow crank. Heat soak. That dreaded “won’t fire when hot” moment.

The Fix: Real Current Capacity

Our 20” Auxiliary Ground Strap is built the way it should’ve been from the factory.

• 100% USA-Made
• 100% Oxygen-Free Copper (OFC)
• Massive 2/0 Gauge cable – capable of carrying full starter cranking amperage without voltage drop
• Machine-terminated in-house using our 80,000 PSI hydraulic crimper
• Ultra-high-quality copper lugs for maximum conductivity
• Adhesive-lined heavy-duty heat shrink for a sealed, clean, professional finish

This isn’t a generic parts-store cable. This is a purpose-built, high-current solution designed for real performance cars.

Why 2/0 Gauge Matters

When cranking amps spike—especially on cammed, boosted, or high-compression setups—voltage drop is your enemy. The larger the cable, the less resistance. The less resistance, the faster and stronger your starter spins.

Simple physics. No gimmicks.

The Best Hot-Start Solution for the Money

No other hot-start “fix” for your platform offers this level of material quality, current capacity, and build integrity at this price point.

If you’re tired of embarrassing slow cranks in the staging lanes or after a quick fuel stop… this is the upgrade your car actually needs.

Bolt it on. Restore proper current flow. Crank like it should.
