Topic: Clutch Crawler vs Racing

[climber87]

For a daily driver and a casual offroad truck...most likely a lift, etc later should I go with the crawler or racing clutch. Will the crawler work alright for long distance trips 1000+ miles?
I've got a 87 4runner.

HUH??  you mean ceramic or semi metalic??

[climber87 [OP]]

Yeah probably...I was looking at the Marlin clutch kits and they are distinguished by crawling and racing?

Yeah thats what I've been looking at. Now i'd be buying for a 22re 87 and im thinking the crawling (non-ceramic) because the other one sounds like it doesn't have much give to it.

the ceramic clutches  GRAB,  sucks when at a red light

[climber87 [OP]]

gotcha...and the non-ceramic will work just fine with any kind of driving?

[79coyotefrg]

ive had mine 6 years, almost 7 years and still does great

hard wheeling,  muddin, towing daily driving, ive done it all

I have the heavy duty non-ceramic and it works fine.  I have a very sloppy clutch habit/skill, and it's still working fine, despite abuse that would have roasted a stock OEM clutch in under a year.  Best was hammering it up a steep hill in the rain that I was forced to stop on with 4 people in the truck.  Actually slid backwards about a yard due to my tires sliding it was so steep.(ie - tires spinning before grabbing).  Clutch was unfazed. Couldn't care what I was doing to it, near as I could tell. 
(guy behind me, though, was probably needing new shorts by the look on his face)

Stock on a 4 cylinder is/was 900lbs, IIRC.  That's way way too low - basically the same as a stock 2wd pickup/donor of the same year. (oversight, IMO, on Toyota's part)

Note - this is a 1600lb clutch kit on an 87 4Runner at about 4200lbs with the extras I have on it.  Lovely, really.  So far I've heard nobody ever complain about it here.(opposite, really - loads of love for it)

The ceramic will probably be my next one, though, since I personally like a ceramic's feel.  But it really IS on/off - there is an actual slight jerk most of the time when it's put in gear from idle.   95% of people don't seem to like this - go figure - heh.

Oh, ceramics are great off-road, but they also are stupidly easy to stall with stock gearing in first gear in heavy traffic.  There IS no creep or feathering of the clutch in and out.  It's 5mph or neutral, nothing in between.

what about centerforce I , II , or dual frick

[climber87 [OP]]

Plekto thanks a lot...that reasoning makes sense. I think Ill probably go with the 1600 non ceramic. Its only a bit more than the 1200 and i figure I'll appreciate that later.

[Cheesemaker]

Get the 1600 non-ceramic and be done with it!  And don't forget to have the flywheel surfaced, and with the 0.026" (?) step.  Marlin has spendt time figuring out the best step for clutches.  I've got the 1200 and it's nice!    Don't forget to order new flywheel bolts when you order the clutch, just good added ins. 

[climber87 [OP]]

Anything else I should order that doesn't come in the kit?

[Cheesemaker]

Hows the rubber boot look that goes around the clutch fork?  If it's gotten oily the rubber will degrade and get all  and since your there!?!?  I didn't get one, and I wish I did. 

And since your ordering things, don't forget a new shirt, some stickers, a hoodie, a beanie! 



Oh!  How's your gear shift feel?  Is it sloppy?  They got the spacers for that too!  Since you got to take the gear shift out to move the tranny.
