We stand behind our Sixity-branded products. To prove it we offer a FREE one-year limited warranty on all Sixity products, from axles and brake pads to nerf bars and wheel spacers. Your purchase is automatically protected for one year. You won't find this kind of coverage anywhere else! Warranty terms and exclusions apply. Please read the following important details regarding the Sixity Warranty Policy.

  • Warranty excludes normal product lifetime wear-out, wear and tear or abuse, such as worn brake pads or spark plugs, or a headlight which goes out after its useful life.
  • Warranty does not apply to conditions resulting from misuse, abuse, negligence, accident, improper application, improper installation or alteration.
  • Warranty is void on any vehicle that has been altered from the OEM specifications such as performance enhancements to the engine, lowering kits, tires, wheel or suspension components.
  • Just as is the case when you send a product to a manufacturer for repair, you will be responsible for paying all shipping costs - both the cost of shipping your items to Sixity and the cost of Sixity shipping them back to you.
