Top Street Performance is a privately-owned company based in Southern California. We have a respectable history in the automotive aftermarket industry, cultivating relationships with a network of quality parts manufacturers along the way. This means that we are able to provide premium parts and bargain pricing, all guaranteed by our one-year warranty.

Thanks to our hard work and dedication, we have been fortunate enough to enjoy steady growth over the past several years. We recently moved from an 18,000 sq ft warehouse in Downey, CA to a 52,000 sq ft facility in Santa Fe Springs, CA. This has allowed us to stock more products, ship orders more quickly and efficiently, and increase our sales and support teams to accommodate more customers.

Customer service is at the center of everything we do at Top Street Performance. Whether you're looking for a part or two for your resto-mod or performance upgrade, or whether you're a shop or distributor looking to add TSP's high-quality performance parts to your product line, we've got you covered. Our friendly and knowledgeable staff is ready to assist you in anything you may need.

TSP has been a proud member of the Specialty Equipment Market Association (SEMA) for over a decade, and we are an authorized retailer of premium products from industry-leading manufacturers.
