Ridetech Coilover preload???

[WallaceMFG]

I can second the recommendation from ridetech not to worry about the preload. My 69 Chevelle was too low after tightening 1.5" from zero preload and I was worried about going more. They told me not to worry about it because the Hyperco springs were very hard to get into coil bind.

As for tightening the spring my shocks came with a spanner wrench specifically for the ridetech shocks. Just take the weight off the shock and it should turn without too much difficulty. Some dry graphite lube will help as well.
