When do I need to regear?

[scottyperry]

I know with my Jeep that the need to regear came early when upgrading to bigger tires but Im not sure if the same rules apply with 4runners ::enter a newb::

Im currently running 265s on my V8 4Runner but plan on making a (large) jump to 315s (eeeek!) at the same time I do a 3" lift. I only assume I will need to get at least 4:10s but is that too low?

4:88?
Bigger?

I made a thread about this a while back with some decent http://www.toyota-4runner.org/4th-gen-t4rs/112905-regearing-v8-3.html


I would say the 315's may need some regaring, the 33"s I have now actually make the truck a hair more sluggish (closer to 8 seconds to 60mph vs. the 7.4 stock). I know when I get around to doing 35"s it'll need some regearing to keep up with the added weight.

Contact ECGS. They can go over your regear options. They actually do a assembled third program. Makes it super easy. With 34 or 35's you will want to regear. I have 33's and pondering regearing.

You will have major rubbing issues unless you are doing some extreme trimming.

You'll also need a body lift. If the 35s are just for looks and street use you should be ok but if you'll be off road and fully flexing you have to do the body mount chop and major trimming to the bumper, etc. There's a lot of extremely capable rigs here running 33s and they handle some pretty gnarly stuff.

When you go 35s it becomes much more expensive, adds more stress to all the IFS components, decreases acceleration AND stopping power. Seems like you've been down this road with a jeep before but be prepared for a bit more work to make them fit on the 4Runner.

I'm sure you did your homework before deciding this route so just playing devils advocate for all the folks contemplating 35s. The larger footprint, sidewall, and ground clearance the 35s provide are nice....but definitely come at high cost. Good luck and post it up when you get it all added.

You need to regear when you get tired of the constant downshifting on hills, poor gas mileage and poor acceleration with big tires.

35s scare me. more so with the 4Runner than with the Jeep. With more and more research my bank account is getting smaller and smaller. :/ It may be a end of all projects kind of projects the way it's looking. Ideally id like to do an axel swap anyway but with this being my DD I'm trying to be practical as well for the road.

Many of run 32 & 33's with good results Offroad. I just mounted 33's but I have run trails in Moab and NM/AZ with few issues on 32's. Quality suspension & skid plates help a ton too.

it depends on wat size 315 u go with. because i looked at a 2 different ones but one size 315 is still a 33 and another bumps it up to a 35. i have a 285/70r17 with stock gears and im thinkin bout going with 4.56 gears jus to help with the down low accerlation and grunt

No need to regear, just add a supercharger!

I'd like to bump this and add some more information on inquiring when to regear. When I bought my 4R it had mud tires on it (it was awful) and I switched them to K02s with ProComp steelies 17s. Then I added maybe 80lbs in the back for my drawer/sleeping platform. Later this year I'm going to be adding another 1xx pounds for a new rear bumper. When I did the switch of the tires and went to Moab I had some issues getting uphill on the freeway. Would adding all this extra weight constitute for a regear? It was suggested to me by friends to run 4.56, I don't know what I'm running now (failure on my part). halp lol

Steel wheels are heavy. You don’t say what size tire you went to. That matters a lot.

Maybe you’re expecting too much out of the 4Runner. These are light vehicles, and the V6 is great stock, but bigger tires and lots of weight will tax it.

4.56 is pretty low for highway cruising if you're running 32-33 inch tires.

Get on Grimm Jeeper, put in your info and see where you want to be. I do a lot of highway driving as my 4Runner is only used to go out west from Pennsylvania and do mild off roading. However, I’m bumping up to a 285/70R17 and looking to swap 3rds for 4.10’s, which will get me back to stock.

For what I do off road, the stock transfer case 2.57 low range is absolutely fine. If you need slower crawling 4.56-4.88 might suit you well. Again, build it for what YOU need. Only you know what that is.

Thanks for the info, right now I'm running 285/70/17 and I know the steelies are heavy af. I don't do anything too nuts when offroading so it isn't a serious crawler and what it has done for me it's been great. I think with all this my fear is something seriously going wrong with all the weight I've added and am going to add; the rear bumper being the last big weighted item. Thanks again
