Big Battery Kit

[J33ps]

I'm running through Cruiser's tips.  This truck is still new to me, and just recently the AW4 transmission has been stuck in 1st gear.  I tested it manually by removing the TCU fuse and driving and it does shift fine.  So now I'm starting with cruiser's tips and knocking out all the basic grounding and little upgrades before I start putting meters on the TPS and such.

 

He suggests the big battery kit.  It's a bone stock truck with no plans to offroad or run auxiliary equipment.  Would I really benefit from this big battery kit upgrade (from jeepcables.com)?  I looked at the addition of the grounding cables and for 20 bucks in NAPA parts I thought I could probably accomplish enough improvement.  Any thoughts?

In my opinion, not necessary if you’re not running a lot of accessaries, lights, stereo, winch, etc. I’ve been using cables from NAPA on my stock ones for years, work perfectly.

That's what I figured too, good to hear some comments to be sure. Thanks for the advice!

I have the jeepcables kit all my jeeps. MJ will only see pavement and has a tiny amp, but I like the kit and figured for the extra cash I'd rather have some proper cables.

I'm in the same boat as you, goal-wise. I'm not doing anything beyond practical, mine isn't even 4x4 anyway. 

 

I did the upgrade kit from Jeepcables on both the MJ and ZJ, and they are stellar kits. On the flip side, I've done similar work on my Landrover and my Bronco II, but I had to buy the cables separately and measure, etc.

 

If you want to take out all of the guess work and upgrade the major cables, get the kit, full stop. 

 

If you aren't seeking a total upgrade or you don't mind doing this job bit by bit, but all means you may be able to save $$$ acquiring the cables to yourself. That is my 2 cents. To be honest, I really wish there was a Jeepcables or KSuspension kit for both my 88 Ranger and 84 BII. Sometimes it's worth it just to buy an extra half hour of your precious time. And I'm still a little bitter that my 51" cable is like 2" too shot for the BII Starter relay to motor...

I built the battery and starter cables for some of my XJs. I do like the design of the Jeep Calbes. More strands is better. Some say better electrical flow. It does bend better. I have use marine grade cables, ie tin coated. I haven't upgraded the alternator cable yet.
