At what rwhp level do you need to uprade rear end parts? I am at 540 rwhp an want to do either 3.90 or 4.10 rear gears. I will do the occasional 1/4 mile at a track with 18x11 inch wheels with 305 Mickey Thompson DRs. I know I can throw $$$ at it but at what levels does stuff really start to break?

I donít think youíre anywhere near needing to worry about man. Especially if dead hook drag runs arenít what you do with the car regularly or isnít the cars main use.

Iím also a bit curious as to what number the forum brain trust provides though🤔 you may get more input in the F/I section though. Iím making 840whp with the stock rear end, lots of guys in that range running the factory set up. I pretty much only do rolls for a few reasons at the moment but Iím not worried about the rear end with that kind of power and not consistently dead hooking digs.....thatís really when **** gives up.

Local guy has somewhere north 700 and broke some stuff a year or two ago running drag radials at a sticky track...

So at 540 I wouldnt worry about it.

NOW if you are in there to do gears, I would probably do a few things anyway(hardened output shafts, new clutches), but I wouldnt open up a good rear end at 540whp...
