Three points:
1. Yes it will help.
2. No, your slipper is not locked down even if the spring is totally collapsed, even though you think it is.
3. DO NOT RUN THE SLIPPER LOCKED DOWN with the pin mod unless you have a bunch of extra idler gears on hand and desire changing them out on a regular basis. You need the slipper to take shock away from the driveline.
Have fun, be prepared to spend 10 or 15 laps re-learning how to drive your truck after the modification. It's totally different, but it's faster.
Well I am stoked if it helps. As for my slipper, yes it is locked down. I have added washers and after running all the packs through it there is zero wear on the pads. None at all. I run all my trucks like this. I just never understood the point of letting it slip. Well I mean I understand it helping with the driveline and those moments I don't let off the throttle fast enough but for general racing around my track I like it locked. Now this is coming from someone who doesn't race that often but I do have a track in my backyard which I drive almost daily with my wife and friends. It's about a 30 second track so it's a decent size. So when i do the pin mod how much slip should I do. The way I know of it is to take it on the street and punch it, if it slips for a couple feet it's good. I guess I will learn when I do the mod. Also what size pin is this. I have about a million different sizes.
Thanks for your help.
Sounds like your belt may be a little tight. Try this simple fix first to see if that helps by adjusting the tension in the front and rear one notch; and/or raise the ride height in the front or lower the rear ride height.
I thought the same as well when I changed the front from position 3 to 1. The rear is at 3. I will try to loosen it one position at a time and see if it helps. I am running the overdrive gear as well.
Thanks
