    Completely satisfied. Holding up well.
    I love this Axel. Lighter than stock and he held up well to extremely fast trail punishment. On a 660 Raptor with long travel setup. I will absolutely consider for any future builds.

    I read in the reviews this axle has. Lifetime warranty. I also read the splines for the hubs and the sprocket wear out quickly. Are the splines covered in this warranty?
    A shopper on Apr 1, 2017
    BEST ANSWER: I checked into this with our Warranty Department and they said that the limited lifetime warranty is only against bending and breaking. Spline wear is not covered. I'm sorry for any inconvenience this may cause.
    How do you adjust the axle?
    A shopper on Sep 5, 2016
    BEST ANSWER: The axle is already wider than the factory but it has a small and a large adapter on each side that you can adjust the width even wider. I personally used the larger spacer adapters then installed my new Tusk billet hubs and used the smaller on the outside of the hubs which is also explained in the paperwork that comes with the axle. Be prepared to widen the from wheels because it causes the atv to turn completely different if only the rear is widened.

    Does this axle give u the option to still keep the stock width?
    A shopper on Apr 11, 2017
    BEST ANSWER: Yes. Purchased one for my LTZ400. It gives you spacers. Depending on what side of the hub you put the spacers depends on the overall width. You will be able to make it stock or add an inch or two of width.
    Would this work well with +3 a arms?
    Adrian G on Mar 21, 2017
    BEST ANSWER: Yes it will work. Depending on which Rims and offset you're using as to how the wheels will be staggered front and rear combo.
    Does the axle come with a new sprocket hub? If not where did you guys who needed to replace your hubs purchase ones that fit this axle? Will a new/used yamaha sprocket hub fit? Thanks!

    Can I buy just the hub castle nuts and washers separately?
    Zack R on Apr 23, 2017
    BEST ANSWER: factory castle nuts are used on these through oem rocky Mountain section or used old nuts of your old axle
    Can this axle be set to stock width? For example if I didn't want to use the spacers to extend it could I simply run it at stock width?
    A shopper on Apr 6, 2017
    BEST ANSWER: The actual width is dependent on the machine. For example, the TRX400EX axle starts out at 2-5/8" wider than stock. After you select your machine in the drop down menu, you can look in the product description and it will have the adjustment range.
    How does the sprocket hub stay on the splines are they pressed on or can they be removed?
    A shopper on Sep 11, 2018
    BEST ANSWER: It has a locking nut, slide the hub onto the spline and then fit the lock nut
    Will the stock hubs, sprocket and brake hub work on this axle?
    DENIS S on Jul 24, 2018
    BEST ANSWER: Yes,Yes and Yes for my 2008 TRX450ER. What makes it adjustable is the spacers that either go on the inside or outside the hubs.
    I just received my new tusk axle and the sprocket hub is loose on the axle. The sprocket hub moves side to side on the axle about 5/16". Is this normal? I have never had an axle with the sprocket hub this loose.
    DOUG H on Mar 22, 2018
    BEST ANSWER: When I ordered a new axle I installed it along a new sprocket hub due my old set up having play side to side and forward and backward, but with the new Tusk axle and new sprocket hub I have no movement in either direction. Wish I could offer more assistance.
    Is this a plus one and a half axle without spacers ?
    John L on Jan 4, 2017
    BEST ANSWER: The Tusk axle is fully adjustable width. The adjustability comes from the spacers they provide you. you simply choose which spacers and how much you would like to add. Go to the max width for dune riding or even off-set one side wider for flat track racing. You get to choose and custom tune your ATV
