    i alredy have a slp clutch kit with both spring helix and ramps but i dont know if it will be sutable for the upgrade i. I know that they are hard on cranks i just rebuilt mine 610$ to fix my crank but i think if i can manage to keep the rpm low i should be fine . Plus i run real good oil

    if you haven't done so already,go to the slp website and download the instructions.that will tell you what they require for rpms and what they will start you off with for jetting,clutching etc.i found a few different things have worked better for my applications but it's a good place to start.

    hummm acording to them peek is 8900 to 9100. i know all about the crank problem on my sled but i did drill out the pto oil hole and im just thinking now. I know if i do this i can fail my crank. witch is not that bad i can fix it. and i dont drive that much . but i would love to see the boy's faces when i blow by them with that roring sound . il sleep on it.

    Trust me man the HP number SLP gives I believe are pretty accurate. Those sleds absolutely rip after you add pipes. Be careful, do it right, run some good oil and hopefully it will run great for you.

    Zeg my XLT 600 runs at 8500 and will smoke a stock xlt bad with only half throttle so get the SLP pipes and run it at 8500. Since youve got a rebuilt crank the pipes shouldont blow it. Also I would reccomend the slp billet heads as well. You will see a big power difference. But dont go near 9200 or yer cranks hours will be numbered. I have the updated crank but I still wont run her at 9200.

    The 23hp gain SLP claims is accurate when setup to their specs. Xlt's rip with triple pipes.
    If I was to put on triple pipes, I would also run EGT gauges to be safe.

    i can see a 23hp gain at the peak but theres no way that those pipes give a 23hp gain right across the powerband...

    Cripes what do you want, no pipe can make consistent hp across the entire powerband. It's just not feasible. Pipe building is all about getting alittle and giving a little. So consistent power isn't going to happen.

    Here's the stock powerband off a 94'...


    I garauntee 23 hp anywhere is a big plus for this sled!

    Stick with the slp pipes, They are the best choice for your setup. I put an ultra motor in my xlt. Its not that simple a job if you want to do it right. $$$$$
