- This is a big three upgrade kit that I can custom make for you using 4awg EB Flex copper cable that is made in the USA.
- You choose the length of wire you want for each of the three wires.
- Wires #1 and #2 will not be covered in flex loom, they will just be black cable. **This is different than what is pictured**
- Wire #3 you can choose your color of flex loom: Blue/Black, Red/Black, Green/Black, or Neon Green. I will install the loom and heatshrink the ends on all three wires.
- You will get all 6 wire ends complete with crimped TINNED COPPER ring terminals and heat shrink (again different than what is pictured, those are copper but this kit comes with one step better: tinned copper rings). These ring terminals can be any combination of sizes 1/4", 5/16", 3/8", or 1/2". I make these kits custom per order so I can make them specially for your build, if you need a special variation on the ring terminals, or even wire ferrules, feel free to request during checkout in the special comments section. I default make these to have 1/4" ring on the alternator charging post, and 5/16" ring on all other ends which seems to fit 95% of cars and can be drilled out to larger sizes if it doesnt. If you need something special, please let me know!
- I also include some premium zip ties with these kits to help you complete your install. Please make sure to keep the cables zip tied up off of the engine which can get very hot.
The 5/16" tinned copper lugs also fit my zinc grounding bolts perfectly which can be purchased separately if needed to complete your big three.
I also sell battery terminals, fuse holders, and circuit breakers to complete your kit. This 4AWG OFC kit I would use for 150a or smaller alternators.
