My assumption as well - and there is no way that slight additional length will counteract the forces causing spring windup. That's why people control the windup with traction bars (or by adding extra leaves to the spring pack).

My last truck had Leafs that were fairly flat. In fact the bottom spring was actually bent backwards. I can see perches like these being a problem in that situation.

Again - that additional length is so insignificant as to have no measureable affect. The perches will cause the same amount of stress as the production versions; only in a slightly different spot on the spring.
