TEIN USA (TUSA) was first established in August 2001 to meet the demands of North and South American consumers. Our original location was in Paramount, California, which is about 25mins outside of Los Angeles. This office handled all US operations including product testing. By 2003 we had outgrown our building, and moved to our current facility in Downey, California. From this location we perform all sales, operations, marketing, repair/ revalving, new product testing, demo vehicle preparation, and West Coast warehousing. TEIN USA is dedicated to providing high quality products at reasonable prices.
