Any 34/78 battery should drop right in. I've got an Odyssey 1000CA/850CCA in my red truck, and two DieHard 900 CA/800CCA batteries in my crew; they fit in the battery trays just fine.

How do you like the Super Starts? I've been having a hell of a time with the DieHards in my 6.5.

The larger battery is normal for my truck. I think the smaller one is listed as an alternate size, when I put my truck into the computer at Walmart. The vans get an even larger battery, but I don't think our battery trays are big enough for it.

I've always ran a 34/78 in every truck; I've never really looked at what the alternate battery options are.
My coworker has a set of big ass marine deep cycles in his GMT800 Suburban, he said he had to flatten out the ends on his battery trays in order to fit them, so I assume with a little bit of effort one could probably mount a set of comically large batteries in our trucks.

I've got a monster battery in the 1500, forget which size. I had to cut the side of the tray and beat it flat for it to fit. You can get a few pieces of paper between it and the overflow nipple on the radiator. I want to say Crown Vic cop cars used it?

Would've been a good time to go top post. Side post have given me trouble on multiple vehicles, and always solved it by making the switch.

I hadn't had any issues with side posts....yet

Yes, the specs call for a 78 series battery, the old battery looked like a lawnmower battery in my battery tray lol

Don't really know yet, I'll get back to you on that, this is the first one I've had

In highschool me and a buddy made a huge battery out of a dozer fit in my 81 F150, that thing outlasted the truck

I put Whamalart's cheapest top-post 850 CCA battery in WCJr. It's a 65 series, and I had to flatten the end of the battery tray to fit it. Works like a champ.

I realized I never mentioned that I “upgraded” the radio. I kinda prefer the OEM look, but after trying 3 different junk yard radios that each had different issues, I added this to my Christmas wish list since my wife was out of ideas. It’s a $40 Amazon special, but it works pretty good surprisingly. I just didn’t feel like any OEM radio was truly worth repairing
