A Midwest Bayless exclusive!
This is a set of racing quality double-spring valve springs made specifically for SOHC and DOHC Fiat or Lancia engines; including those fitted to X19, 128, 124, 131, Lancia Beta, Lancia Scorpion and Yugo.
Excellent choice for high-revving performance street, auto-x or race engines.
Narrow wire double-spring designs work extremely well with conventional and higher-lift cams up to .430" without coil binding.
We use these in ALL our race cars with working RPMs to 9500 (and the occasional missed shift over 10K) without valve float.
These are cheap insurance on a trick engine build.
