Yellow Speed Racing's Dynamic Pro Gravel Rally Coilover Kits are an affordable coilover option for driver's that prefer the adrenaline of off road racing over normal track racing. Dynamic Pro Gravel Rally Features: Long shock travel (similar length to OEM travel) (varies by application) Allow vehicle to be raised higher than factory suspension (depending on application) Lower bracket is designed for additional rigidity and strength. For suspension systems utilizing a MacPherson strut type, a inverted monotube design is utilized to reduce excessive heat transfer from the brake system to the damping oil and shock piston. This suspension system comes standard with pillow ball upper mounts (where applicable). For some race regulations, we also offer R/U (hardened rubber upper mount) as an alternative for customers. Front upper mount is 4mm thicker than the standard upper mount (depending on applications). 55mm shock bodies with monotube inverted shock insert are utilized to ensure maximum durability and strength.
