Speed Unlimited started from humble beginnings and grew into one of the largest and well know "Speed Shops" on the east coast. In 1967 Speed Unlimited was founded as a one-person business in Suitland, Maryland. Word of the company's large in-stock inventory and good prices quickly spread. More room for inventory and display space was needed so a move to our current 5,000 square foot Retail Superstore was made. Speed Unlimited continued over the years to add more product lines, a very knowledgeable sales staff. Today Speed Unlimited ships high performance parts worldwide.
