Jeep Wrangler TJ I-4 4 Cyl DOHC 2.4L 2003-2006 Standard Kit #4423S

Upgrade the electrical system on your Jeep Wrangler TJ with this heavy-duty 2-gauge standard battery cable kit, built specifically for 2003–2006 models with the 2.4L Power Tech inline-four.

Factory cables on these TJs commonly develop corrosion and voltage drop over time. This kit replaces the main positive, negative, and alternator cables with larger-gauge pure copper cable for stronger cranking power and improved charging reliability.

• 2-gauge positive battery cable with 4-gauge fuse block lead
• 2-gauge negative battery cable with 6-gauge chassis ground
• 6-gauge alternator cable with fuse link
• Starter lug cover
• Anti-corrosion battery washers
• Anti-corrosion bolts

Optional Add-On: Terminal Covers – recommended for added protection against accidental shorts and a cleaner finished look.

Fitment: 2003, 2004, 2005, 2006 Jeep Wrangler TJ with 2.4L I-4

Hand-built in the USA. A straightforward, durable replacement that restores solid starting and charging performance.
