meh, ok.
1) set the diff the best you can with your hands. I can feel once its close and back off 1/8-1/4 turn.
2) start with the slipper too loose. then keep doing the throttle test until you achieve 2 inches. 2 inches should prevent the diff from barking on landings.


So start with the diff first, then slowly adjust the slipper until 2 inches. "if" it barks before 2 inches, just tighten it a little. your just giving a short burst to check the bark. Not punching and hold it. You may need to tighten it a 1/16 as it breaks in a little.

lower gearing punch, higher gearing top speed. just like a 5 speed tranny, but you only get one gear, lol.

How are you guys running your slipper in stock buggy? I heard some say to lock it but when I do the motor stalls out when I hold the tires and blip the throttle. Is that normal? I set it a little loose and it seems fine but its barely pulling the tires off the ground.

for 17.5 that can happen. you can put a smaller pinion in for the 2 inches to give it more torque. then once you set it, put your pinion for racing back in. The slipper is there to save your diff. its not traction control.

Yea just a little different then setting it with my 8.5. I havent ran 17.5 in a while. I am going to set it as tight as I can without stalling the motor.

I've been running 1.6's/27.5,30AE/black fr,grn rear springs for a while with decent results. I run on a hard packed clay track with high traction and minimal dust and small jumps. I dont want to spend the dough on tapered pistons so would going to the 1.7's with a little thicker oil give me better low speed dampening (Stop the pogoing)?

is where im at right now. pretty close to due's

It will make the car more reactive and could be ideal in a lower traction or smooth track, but it feels inconsistent and worse than 1.6 at a track like Newreds where it's somewhat rutted up. You might want to give the green fronts a shot as well with 32.5/30 and 1.6's

The track i was taking about is FZRC(You are familiar with that one). I guess I will try the tapered pistons,why not?Lol!

really?

I'm giving the 1.4 tapered pistons a try this weekend. A lot of it is just preference and not necessarily faster or slower. We have a lot of room for error in offroad, lol.

The tappered 1.4s help the rebound immensely, ran them a week ago and felt good. Just been trying a lot of suspension stuff lately

that was my next question, what is the difference with the same ratios but different size pinions and spurs. bigger spur smaller pinion is more torque, so bigger pinion smaller spur is less torque more horsepower, high speed?

correct

spur divided by pinion
smaller number=more top speed and heat/load on motor
bigger number=more torque and less heat/load on motor.

ex. 81/16=5.063, 81/14=5.786

with my experience in my 4.2 when you build a diff the most critical part is the break-in, after about 4 diffs that didnt last more than 2 race days i finally figured out how to build one, break-in, and setting to make it last.
