*Why Titanium: There is a myth in our industry that Chromoly is the best material to make fasteners from.  It is just that – a myth.   But isn’t Titanium more brittle than Chromoly?  Yes, but that doesn’t mean Titanium is “brittle”, or isn’t the strongest common use material known to man.  It is just more brittle in one aspect than Chromoly, but not by much.  There are several factors to consider when determining the strength of a material, and in most of those respects Ti is better.  Titanium has a higher tensile strength than Chromoly, it is also FAR MORE resistant to heat and corrosion than Chromoly, and it is HALF THE WEIGHT of Chromoly.  Even better, our Titanium fasteners COST THE SAME OR LESS THAN CHROMOLY.  The simple truth is that both materials are more than strong enough to withstand the heat and tension any powersports vehicle generates.  In one or two areas Chromoly may be stronger, but overall the Ti fastener is a better-quality product.  We back up these statements by being the only company that offers a LIFETIME WARRANTY* on all of our Titanium fasteners.   

**Warranty: Unless otherwise stated, we stand behind all parts we sell 100%.  This product is NOT DIY.  Over 99% of people in the world are not qualified to build an engine.  We ALWAYS STRONGLY recommend this be done by a qualified, experienced mechanic.  STUD WARRANTY: If for any reason a stud fails during use, not installation, we will send an entire new stud kit.  No other parts or any labor are included, and it cannot be converted to a refund or discount on any order.  For any warranty to be considered the part(s) in question must first be sent back to us for inspection.  We do not warranty parts based on phone calls, photos, emails, what you read online, or another mechanic's assessment alone.

Feedback: Positive reviews and feedback are greatly appreciated.  We have changed the way we do business in response to customer concerns and receiving positive feedback / reviews when an order goes the way it is supposed to is a huge help.  Also, we will give you a discount on your next order if you take the 2-3 minutes required to leave us a good review!  But we want to know the good and the bad.  We just ask that if you have an issue with your order please contact us first.  If an order is sent incomplete or incorrect we correct it IMMEDIATELY.  Work with us and we will always work with you.
