What is your average transit time?

  • Average transit time is 2-3 days on most orders, but we’ll be happy to give you an ETA if you give us a call.

Will you ship out the item the same day that it is ordered?

  • Most items will ship same day if we receive the order by 3PM EST. This does not include custom orders or items that need further fabrication (ie welding up a battery box.)

Otherwise, feel free to shoot us an email and we’ll get back to you that day or the next. It won’t bother us if you call back either.


Warranty and Returns:

Do you charge a restocking fee on returns?

  • There are NO RESTOCKING FEES on returned items that have not been used and are returned with all of the original packaging. You will however have to get the item to us.

Can I return a custom part?

  • We do not accept returns on custom parts or special order items.

What if Billet Proof sends me the wrong part? Do I still pay return shipping?

  • Absolutely not. We will handle all return shipping if an item is sent out in error or if the part is damaged.

What is your warranty policy?

  • Most items have a hassle-free 30-day return policy.

  • Some warranties are brand specific, but we’ll work alongside you to make sure that your claim is dealt with in a timely manner.

Can I return a used battery or tuner?

  • We do not accept returns on used batteries (unless they are proven to be defective) or used tuners/electronics.


Custom Parts:

Do you make custom Motorcycle Parts?

  • Yes, we do. However, we are not set-up for sheet metal work for projects like custom gas tanks and fenders. We can customize a gas tank for you or add one of our custom fuel gauge kits, but it would far too time consuming/expensive to fabricate a gas tank or fender from scratch. Contact us directly for shops that we recommend for sheet metal work.

  • We are a full service machine shop otherwise.

How do I get my idea to you?

  • If you already have a drawing please send in a vector file for a quote to If you do not have access to CAD or any other design programs, please send us a detailed drawing with all necessary measurements and we’ll do our best to provide a quote. Please note that if you send in a hand drawing or non-vector file, we are going to have to “draw” or design the part first, which will add to the final cost of the part.

What is the typical lead-time on a custom order?

  • Our typical lead-time is 2-3 weeks, however, that is after you have approved the drawing and that does not include any kind of finishing or coating after the part is machined.

  • Please note that custom parts cannot be returned. All sales are final.

  • Coupon codes cannot be applied to custom orders.

Can you install one of your custom fuel gauges on my tank?

  • Yes, we can. If you aren't local and cannot drop the tank off at our shop, you can either ship the tank to us and we'll give you a price for return shipping once we receive it. Or we can provide you with a quote for shipping both ways if we are provided with the weight and dimensions of the tank (with ample padding.) Once the funds are received, we will send you a pre-paid shipping label, so that all you have to do is hand the package over to a UPS driver or drop it off at a nearby UPS Store.
  • Keep in mind that we will need to grind off any finish or filler etc that is near the location of the installation, which may cost more depending on what is required to prep the area. Grinding off a coat of paint in the location of the installation will not cost anything additional.
  • Please make sure to thoroughly clean the entire tank inside and out to rid it of any gas or other flammable liquids and fumes prior to shipping the tank to us. There will be an additional “fuel prep” charge of $30 to further prep a used tank ie a tank that has had fuel in it at one point in its life. There will be no “fuel prep” charge on new tanks.
  • Prices for a fuel gauge installation on a new steel tank: Does NOT include the cost of the part.
    • Fuel Hose Kit = $60
    • 12 Gauge Sight Glass = $60
    • 12 Gauge Sight Glass with "Flush/Frenched" Bung = $100 (the installation location will have to be relatively flat surface)
    • "FU" Gauge (Aluminum of Brass) = $80
    • Brass Barrel Gauge = $50
  • Note: There is an additional charge of $25 if the tank is Aluminum.

Can you make a custom tank for my bike?

  • Although we are capable of making custom tanks, we are not properly set-up to do so, which would result in a lengthy and therefore very expensive process. Somewhere in the neighborhood of $2,000. Again, this is strictly based on the fact that it would take us much longer to make a tank than a shop that focuses on sheet metal work on a daily basis.
  • We recommend two shops for taking on a job like this:
  • Nichols Paint and Fab (815)432-1717
  • Voodoo Choppers (248) 299-8200)


Coupon Codes:

Do you have a coupon code for my order?

  • Please look at our most recent social media posts on Facebook or Instagram to see if we have any codes running.

  • Please note that coupon codes cannot be applied to custom orders.


Dealer Inquiries:

Can I become a dealer for Billet Proof and/or Aeromach?

  • All dealers are welcome to offer Aeromach brand parts. Please send us an email at for all dealer inquiries.

  • We are not accepting dealer inquiries for Billet Proof Designs at this time.



Can I have some stickers?

  • Sure. All orders come with stickers. Otherwise, just send us an envelope with an addressed and pre-paid return envelope and we’ll hook you up.
