Whats the biggest size battery you guys have fit under your hood? I have my agm that I had in the trunk of my charger and about a foot long and ten inches tall, I fit it in the stock space but it definitely wasn't stable in there and was crammed up against the air filter

A D3400 or D3100 fits I believe.

Group 34 is stock replacement size for 99-06, I don't believe a group 31 will fit, it will hit the fan shroud. Group 48 is stock replacement for 07+, same deal with group 31 I think.
