Company History

Speed Unlimited Performance has been serving the high performance automotive industry since 1967, we're well known as the "In Stock Speed Shop". We have seen trends come and go and we have changed with them. Our passion is providing you with the high quality parts you need, at the low prices you want, with the great service you deserve. 

We are not just a small office or internet only company, we stock the parts we sell in our huge warehouse and retail showroom. We purchase directly from the most recognized manufacturers so we can offer you the best prices.

For over 47 years, Speed Unlimited Performance has been a leader in high performance, offering a huge selection of parts for virtually everyone from racers to street rodders, musclecars, off-roaders, and sport compact fans. We service our local customers from Maryland, Virginia, Washington DC, Delaware, Pennsylvania, and even West Virginia.
Our 5,000 square foot showroom is packed with today's hottest brands and accessories. If you ever thought reading about the newest parts in the magazines is nice but actually being able to touch and see them first hand would be great, then you need to stop by and visit our showroom.
