This extreme racing valve spring kit from Kelford Cams is made for the BMW B58 and S58 3.0L inline-six engines. The springs are progressively wound PACALOY beehive units with titanium retainers, and a precision machined spring seat raises the seat pressure for builds running high boost and high horsepower. Kelford says the kit is designed for its Stage 2 and Stage 3 camshafts in engines making over 1000HP. Kelford quotes 105lb of seat pressure at a 35mm installed height and 210lb at 10.8mm of valve lift, with a coil bind height of 23.6mm.
