A glimpse of Stellar Automotive Group
Stellar Automotive Group began the journey in the transmission aftermarket in 1990 by making custom ring kits. Since then, many other product lines were added. Stellar has recently relocated to Seville, Ohio and added a warehouse in Santa Ana, California. Stellar continues to find more ways to better service its customers, including the addition of more product lines … inside and outside the automatic transmission.

Think you’re out of options? Think Stellar Automotive Group.
Most companies only offer one kit for each application, even though there are dozens of possibilities. With 20 years of kit-making experience, we will customize the right bill
of materials to suit your needs.

We customize all kits: bushing kits, washer kits, ring kits, ring and seal kits, hard part kits, and piston kits. Best of all, our options do not stop with kits. When available, Stellar offers both an OE version as well as a quality aftermarket version on bulk parts.

Advertise your company with Stellar’s custom kits.
We can print your company logo on each and every custom kit that you order. By printing your logo, contact information, part number, website address, or other information on our custom kits, Stellar will help you promote your company.

Anything custom-made costs more and takes longer to get, right?

With updated equipment and a new database, Stellar is streamlined and more efficient than ever before, resulting in shorter lead times — regardless of the size of your order. Need only one piece? No problem! At Stellar, we make it convenient and simple to give our customers what they want when they want it.
