Please Read Before Contacting

Have questions on the weekends or nights? Feel free to send us an or e-mail, text message, (please save calls for during hours) and we'll do our best to answer. Worst case; we won't get back to you until Monday(or the following day if on a weeknight).

Urgent contacting: If you have something that needs immediate attention try and call if it's during business hours.  If you don't get an answer or it's after business hours, send us an e-mail with ****URGENT**** in the title.  This will be your best shot at getting in touch with us and letting us know it can't wait.

Some days and especially early week can be extremely busy for us.  No matter how you get ahold of us, we will get back to you. We work like crazy to try and keep in contact with everyone, and at times this can be a struggle.  Your patience is greatly appreciated as we try to help customers in the order they contacted us.  

We have great service, not to be confused with fast service!  Although many times we are fast as well.


E-mail is the best way to reach us.  This gives us the ability to keep things organized and reach back to customers in the order they contacted us, speeding up our contact time. This also allows us to easily attach links or files that are needed to help you.  Feel free to send an e-mail using the contact form above or by sending one to

Text Messages

Text message is another great way to reach us.  While typing on the phone is a bit harder than on the computer(e-mail), quick to average length questions are encouraged to send via text.  This can work easily for sending picture of something you need help with as well.

Phone Calls

Phones are a great way to contact us if you have lengthy questions. Being a small shop, most the time it's just 1 person answering the phone at a time. In this industry questions are great, but that means our conversations can be lengthy.  This can make us hard to reach in the busy times.  Until we catch up with previous callers, we do not answer new calls as we believe this is unfair to those that contacted us first.  In the busiest of times we can be out as far as 48 hours on call backs.  Hold out for us you'll get the most knowledgable person possible on the line, not someone who just walked into the industry.  Remember we have great service, not fast service.... sometimes though we are fast as well!

Web Orders: Ordering online is by far the easiest way to purchase our products and have them shipped quickly.  Online orders are streamlined into our shipping system which makes the process extremely easy on both of us.

E-Mail Order: We can also take your order over e-mail.  If you have a custom order or questions about what to order just send us an e-mail and we can help.  When you decide what you want (or if you already know) send us the final parts you'd like, your shipping address, full name, and phone number.  We can then send an e-mail invoice with pay link in our quickbooks system for those that want to pay via credit card, or send a paypal invoice.

Phone Orders:  We can easily take your order over the phone if you know what you want, or we can help you figure out the best parts and then get the order placed.  Like said previously, please be patient with us on the phones as we can be anywhere from 0-36 hours out on answering/calling you back.

Return Policy

We are easy people to deal with, and we ask the same of you.  If you have any issues, let us know and we'll work to find a solution and compromise.  We do our best to have quality parts but keep in mind all aftermarket parts can take a bit of customization to make work as we push the limits to perform better.  If a part is needed to be returned for any reason, please make sure you okay it with us first, and always have your name and phone number inside the box.  Returns for a refund are only available for new parts, and are subject for a 15% restocking fee to recoup costs(order processing, shipping, receiving, and repackaging).  We cannot accept returns on electrical parts or items have have been used.

USPS (United States Postal Service)

Aftermarket Assassins ships out daily using USPS.  This shipping method is our standard because it's quick and cheap! Normally, domestic orders go out Priority mail which is a 2-3 day service including Saturday(bonus day compared to other carriers). Shipping cutoff time is 1pm CST for USPS shipping.  If your order was placed before this time, your order is still not guaranteed to go out the same day.  If you need something sent out right away, please contact us.  


We also ship out UPS daily.  Most of our larger packages go this route, or express packages.  Exhausts and other large shipments will go out UPS ground(they are too big for USPS). 

International shipping

International shipments will normally use USPS Priority Mail International (5-10 day service), but we can also ship via DHL express or UPS Express if you call or e-mail.
