I'm in the market for a new clutch. The truck is currently stock with 31's but am planning to build up and run 33's sooner than later. I've had great experience with a Dual friction center force clutch on my Honda civic but am open to suggestions.

 

People seem to think the put together clutch kit by Marlin Crawler is a hot set up.

I might try that next time.

I am running a Luk clutch in my Tacoma and I hope a Aisin Clutch in my 92 4Runner both with the 3.4

Difference between a truck and 4Runner but I can`t tell much difference then very little places the clutch gets used hard enough to get hot.

That is what makes a good clutch being able to get hot with out being killed in a short time period.

 

Yah all the research I've done points towards Marlins, good price too!

 

Ive had good luck with Luk clutches. Seems Marlins are never in stock. Can be had at any parts store, seems to be around $130.

 

I have had a few of the Marlin HD clutches and would recommend them if you can get one...

 

I got my last Aisin clutch from Rockauto and liked it. I just run 31s and like it real well. Not sure what 33s would do for it.

 

Running 32's with stock clutch and zero problems

 

The stress on a clutch is generally unrelated to gearing and tire size. The clutch has to handle max engine torque, which doesn't change regardless of whether you're running 29" tires or 40" ones, or 4.10 gears vs. 5.29's.

What does matter is your use model in terms of how much you slip the clutch. Slipping the clutch generates heat, and some designs are better at dealing with that than others. If you're starting heavy trailers on hills, or doing a lot of rock-crawling that requires clutch slipping, you probably will want a heavy-duty clutch. Otherwise, the stock Aisin will do you just fine.

 

Sorry, but that's wrong. Big tires and/or high gear ratios will wear out a clutch disc faster.

 

Only because you tend to slip it more. The torque on the clutch is exactly the same unless you modify the engine. It's driving habits that change with gearing and tire size that make the difference.

 

I just installed a LCE 2100# clutch on my 3.4 s/c swapped 4Runner. I initially wanted Marlin but they were out of stock. They said 2 weeks, was more like a month.

I was worried about the clutch pedal being more difficult but it isn't. I have about 1k miles on it so far and I highly recommend the LCE clutch.

 

In that case he is right bigger tires and higher gears cause most to slip the clutch more.

It all comes down to your driving habits .

I knew one person drove with his foot on the clutch pedal never could figure out why he had a clutch release bearing problem no matter how often something was said .
