410s would certainly help. It'd be nice if I had them to judge the difference but I think I'd still regear. The power isn't the problem, it's the transmission. Chrysler has been known for **** transmissions for years, they just can't take heat well. Maybe a better torque converter would help but ultimately regearing is the right step when going with bigger tires. I'm sure if I had 410s I'd probably wait longer but I've now got two connections to get gears done and relatively speaking their prices aren't terrible just have to wait a bit.
Appreciate the comments I'm super happy with the results and glad I jumped for 37s over 35s.
