Coil Savers are a unique design to protect your shock seals. They are designed to protect the inner shaft from rocks and debris, preventing divots and pits in the shaft bringing dust and mud into the seals. Coil Savers feature quick and easy installation without the hassle of removing your shocks from your car. Simply wrap around and velcro together. You want to make sure they are snug on the coil and covering the shaft. Do not get them too tight to where they are squeezed in between the spring, but snug enough so they do not move. They will compress and rebound with the coil, staying in place, keeping that inner shaft protected from the elements flying at it. The ProSeries line features the same design and fit but are now made out of our NEW FlexPower material which is more durable than the original Coil Savers. The NEW FlexPower material will also tolerate the weather a little better as well as has increased flexibility preventing cracks in the material. We have added 2 new sizes to our ProSeries Coil Saver line allowing for a wider range of vehicles we can protect. The new sizes are ‘1.5 to 2.0' and ‘3.0 to 3.5'. ProSeries Coil Savers are available in 4 sizes: ‘1.5 to 2.0', '2.0 to 2.5', ‘2.5 to 3.0' and ‘3.0 to 3.5'. There is 4 inches of heavy duty Velcro that allows you to go smaller or larger based on the coil diameter. They are designed to protect the inner shaft from rocks and debris, preventing divots and pits in the shaft .You can run them with only using an inch or two of the Velcro and not have any concern with the Coil Saver coming off. They are only available in black and come as a set of two starting at $34.95.
