I am very disappointed with my experience from ordering from them. I selected to buy from them based on the prices and positive reviews in regard to shipping, however, I placed an order over the phone on 3/31/26 and was told that my order was to ship from Indiana to SC and that it would ship that same day and that I should receive it by Friday 3/3 and that I would receive a tracking number when it shipped. I called them today, 3/2, to see if it shipped as I did not receive a tracking number. They informed me that it is shipping from CA and gave to me a tracking number that has an ETA of 4/7. What I am disappointed about is that #1 I would really like to get the parts on my car, and #2 it is really interfering either way my schedule planning around installation at a shop. They may very well be a middle man operation brokering and outsourcing parts for sales. If they were accurate from the beginning with reliable information from first contact I would have been able prepared for delivery. I don’t think that I will trust them to order from again, I would rather pay a little bit more for reliability.

Unbelievable super fast shipping.

It fit very tight, like I had hoped for.

Ordered a T56 magnum and got the wrong gear ratio. The site lists 2.97 and 2.66 but doesn't show the ratios for 2.97 or say that it's a wide ratio. I began an exchange and was told to figure out how to get it back to their supplier on my own. No help with setting up shipping even though I offered to pay for it. Then I was told they asked the supplier to arrange shipping and they said no. The supplier told me they never asked so I was lied to. Really not much was done to help with the exchange at all other than issue an RMA number. I contacted the supplier directly and they setup shipping and exchange no problem at all. All lethal did was place an order on my behalf to some other company, like an Amazon store.

I ordered a AFE cold air intake for my 2009 cts v. The price was low and quality was great with free shipping. My order was processed shipped and delivered in less than 24 hrs!

Yes to order the people over at lethal performance are very helpful. They got back to me really fast and I got everything I needed thank you

Very impressed with the outstanding customer service that I received. There was an issue with my order, which was my fault, to confirm which parts I actually needed. This level of service does not happen everywhere. I will definitely be returning in the future.

I purchased a set of head gaskets that said online in stock called a week later to find out that it wasn’t in stock and would have to wait a couple weeks for them to ship So I tried to. Cancel and couldn’t cancel till I got the gaskets and then have to fill out a return form to send them back They said they were customer made is why I couldn’t just cancel them But I called COMETIC gaskets and ordered a set that they had and received them in 3 days So now I’m out 400 bucks till they decide they can refund my money And probably will charge me a restocking fee Won’t never buy there again
