Using the DC Sports Front Strut Bar on your 89 - 93 Nissan 240sx is simple. Just mount it between the strut towers. Make sure to check that all the connections are secure before you start driving. When it comes to maintenance, there's not much to do. Every few months, give it a visual inspection. Look for any signs of rust or damage. If you spot any issues, contact our customer service. Also, avoid driving through extremely harsh conditions as this could potentially affect the strut bar's performance.
