So as a Diesel enthusiasts and helicopter mechanic the drive for precision and excellence is high. HSP goes above and beyond that! The attention to detail, the costumer service is off the charts. I being military and working Aviation am very meticulous about everything! While assembling my track bar kit found 2 rolled threads. Likely from welding the bungs in. HSP went above and beyond to answer my questions and there willingness to replace the product and offer gear or discounts though not needed was very impressive and appreciated! Im sold if they make the product or sell the product i will be buying from HSP! Outstanding job all around!!
