Easily upgrade your BMW's main ground cable with our direct replacement ground cables! As your vehicle ages and is exposed to the elements, the factory unshielded ground cables become corroded and often lead to electrical issues, such as the . Our upgraded ground cables are made from 2 AWG sealed copper welding cable with tin-plated copper lugs and sealed with high temperature and high-wear resistant heat shrink to keep water out of the cable. Our cables are designed to withstand all types of weather and environments while resisting corrosion for years to come.
If you do not see a ground cable for your chassis, please reach out to us via our Contact Us page and we will be happy to make one for you.
Note: The E36 and E46 Ground cables come in a length of either 270mm or 380mm. The 270mm cables are direct replacements for part # 12421724740. The 380mm cables are direct replacements for part # 12421737755. Although they are different lengths and part #'s, they should be interchangeable for most E36 and E46 models. However, we recommend that you verify which cable length is suitable for your needs prior to purchasing.
The installation required to install most cables is very straightforward and involves unbolting the factory-installed cable and directly replacing it with our upgraded cable. Below is an install video for an RWD F10 535i provided by Turbo Spool on YouTube:

Customer Reviews
Bought both the stock length and the extended version. I have two e36’s, one is mostly stock, so I replaced the stock cable with the stock length Arc Terminator cable. Other e36 has a bmw v8 swap, and I bought the extended cable as a shot in the dark. It ended up being the perfect length! Very very pleased with my order, both cables are well built with nice terminals and nice heat shrink! I think these cables will easily hold up just as long, if not longer than the stock cables did!
I am blown away on the quality of the ground wires that I ordered from Arc! They took their time constructing this upgrade. Will order from them again for sure!
As a N54 owner and builder, it’s very common for the OEM Ground Strap to fail. ArcTerminator products absolutely exceed expectations and their customer service is absolutely next level! I replaced the ground strap on my car as preventative maintenance and have no doubt that I will never have to worry about it again! The new one is fully insulated and sealed from moisture and other harmful road contaminants and the wire is heavy duty (I want to say 4 gauge). I also ordered a set of the cowl covers they offer which they made for me in a custom color and the fitment was absolutely amazing! A few months back I also ordered an ekpm cooler which I now believe is necessary for every E9X especially in California summers where I live! Thank you Arc Terminator you guys are awesome!
Direct replacement, fast shipping, high quality! Def recommend.
Had no electrical issue to begin with but for the price definitely worth installing proactively.
Very simple install, took me 10 minutes. Would not recommend going with the OEM as this is so much more durable. 10/10 recommended
