    walker evans velocity/ fox internal bypass/king internal bypass/elka 2.5

    What's with the KOH trophy? That's just a participation one. Another food for thought is having shock service done. If you buy shocks that no one has, then most likely no one will have parts or great valving available for them.

    Rear Trailing Arms - Cognito, Racer Tech, Holz, HCR, Lone Star...

    Holz trailing arms are 8 pounds lighter total. As long as you have a 5" back space wheel or less you will be fine. But you cannot run a stock rear wheel. They also have a mud guard that bolt to their arm.

    There is no such product that can work for all UTVs. They are all built for each model's particular suspension design.

    Build For Race Without Buying A UTV

    For how much time you have researched part numbers and looked at parts diagrams, you could have stripped a complete car down to the frame. Also, what dealer has all of those parts in stock?

    Official UTVUnderground 2013 Baja 1000 UPDATES

    Around 4 or 5am 1934 was only 10-15 miles back from 1932. Both cars were updated close. So if 1934 kept that pace, they should be second on the road.

    Video of XP1000 vs XP900.. Drag Race

    This is as real as it gets. Give the XP1000 6 months to a years and let people start making race cars out of them. Then you will see some more real world facts that a Maverick is not going to be as fast as a Polaris.

    Video of XP1000 vs XP900.. Drag Race

    So all but the Kroyer powered XP900 were COMPLETELY STOCK with close to the same gas, driving on the same road, in 4wd so that there would be no tire spin, and with the same driver from a dead stop until he let off. If you look at the top speed and the distance you can see that our driver just...

    Video of XP1000 vs XP900.. Drag Race

    Real world? So your saying that both drivers weighed the same, had close to the same gas in the tank, same traction, and both have perfect timing when to hit the gas? You must be a MTV reality star if that's real world. And again...300 feet is not that far. Also how many belts have you melted...

    Video of XP1000 vs XP900.. Drag Race

    Run all three on a radar gun that can track acceleration, speed, and distance. Then you will see that stock for stock the XP1000 is way faster than the XP900, and the XP900 is faster than the than the Maverick. And this is from 0 mph to 70 mph. Not 150 yards.

    Shock revalving for dummies....

    I would not go from 12 to 8 or 12 to 20. Go 12 to 10 or 12 to 15. Small adjustments do a lot. Also if you are not far off on set up you don't want to make such a big change.

    2013 BITD VEGAS to RENO

    To bad the 1000cc engine is not OEM to the 900 chassis. It will be interesting to find out how much power can be made without being able to bore or stroke the motor.

    Shock revalving for dummies....

    Both Walker Evans and Fox sell shims. Im not sure if it is only to dealers though. But Getting a whole stack like from Fox would be fine, I just would not swap the complete stack at once. Lets just say this is your stack and you are having problems with bucking very badly; 1.42x.010x.504 Low...

    Shock revalving for dummies....

    The Fox valving chart is very basic and does not come close to what racers have in their shocks for valving. First identify what your problem is.(too soft rear rebound) Second take apart your shock and measure the diameter and thickness of every shim in the problem stack. Third would be to...

    BITD weight and teardown

    You should not need to know what anyone else weighs to build a car. Your goal should be to build a LEGAL car that is lightest you can.

    BITD weight and teardown

    I do not understand why would they separate a class because of weight. That goes back to who can build a LEGAL but light car. These UTVs are not much different in weight from the factory. Yes the 4 seaters weight more but the wheel base you gain is the advantage they are looking for and if they...

    BITD weight and teardown

    Lets settle down a bit... Lets not speculate why Sappington wanted to weight the cars. If saftey is the main reason to start checking material thickness, then so be it. But I think it (how ever they want to check for it)should be done at the first race that the vehicle is entered in and then...

    Fox Shox dilemma

    XP900 shocks will work but will need to be completely re-tuned for the XP4. The Walker Evans shocks are great reliable shocks. The fronts are 2.0 bodies which saves weight on the front end. The Podium X shocks only advantage over the WER shocks are that you can fine tune them with the DSC and...
