These tie rod radius arms (or radius tubes) are made from high quality billet steel and are as tough as you can find on the market today. These are BRAND NEW surplus from a top NASCAR team. These are a very high dollar part that can be very hard to come by unless you have the deep pockets of a NASCAR race team. These tie rod sleeves have 3/4-16 RH male threads on one end and 3/4-16 RH female threads and they measure 8.75" in length. They are gun drilled to reduce weight without reducing durability. These are the best that money can buy and they will not last long at our low prices. You will get two tie rod sleeves for the list price! This is a full set to do one vehicle. They are in perfect shape and ready to install. If you want suspension parts that can hold up to 200 mile an hour speeds in the turns, look no further! Please take minute to see our other items.
