4Runner 2 Report post Posted February 16, 2014 I don't really know where to put this so I'll just put it here. I have a question. I don't know if anyone will know this but it's worth a shot. I am building a LT1383 backed up to a 60E. I don't know what kind of power I'm going to be making but it's more then stock and I'll be spinning 42" tall tires. It is rebuilt and has a shift kit. Do you think that this will hold up to rock crawling?? Thanks in advance Share this post Link to post Share on other sites

4Runner 2 Report post Posted February 20, 2014 Back when I worked on this I didn't know any better. And it may be. Had a shop do it. Told him what I wanted it for and handed it to him. I put 13,000 on it and now it's been sitting with the motor for 4+ years. Just getting ready to finish it finally 1 Share this post Link to post Share on other sites
zippy 15 Report post Posted March 16, 2014 If the 60E has any decent parts in it and has a good cooler it should be fine. The 3.06 first gear in the 60E make it a decent crawler as long as the diff's and t-case have gearing to back your 42's. I would assume you're up in the 5.38 range for gear ratio?

4Runner 2 Report post Posted May 1, 2014 No. I'm running 4:88's and if I need more torque/power I'll do what's called a doubler kit and do 4:10's. I have heard problems more about cases breaking. I don't know Share this post Link to post Share on other sites
zippy 15 Report post Posted June 16, 2014 Running a 4.88 gear and a 42" tire is quite conservative. The case should be able to handle it, but if you're concerned step up to the newer style case with the removable bell housing which is alot stronger.
