The single shot suspension found in 2016-18 Apex and Vector are hard on relay rod bushings. The stock rods are made from aluminum and can stretch. They also will wear out to the point of failure once bushings disintegrate. These HD rods are constructed from stainless steel to better resist stretch and will also wear much better if bushings do disintegrate. The rods ship with brand new bushings installed in them.

Retail price per set is $110
