Early LAKOTAs made prior to 2006 had standard coil springs but in early 2005 some were shipped with springs that were about 18-22% stronger than specification.

You can identify these “too-strong” springs because the loops at either end are off-set by 90 degrees instead of being “in-line”.
These springs should not be used, especially in high wind sites. The stronger springs tend make the turbine furl late in high winds and can shortening the life of your turbine. Also, the softer spring material was prone to breaking off at the upper spring hook or loop. Both spring and upper stud should be replaced with an available kit as soon as practical.
