Ive been messaging ihparts folks about getting some bilstien shocks and having to measure the distance from the top shock mount to the bottom one im only getting 21 inches in the front with a 3 inch lift. The current 16 year old shocks have a spec of 24.7" extended, and was expecting to get a measurement closer to that. 21" is whats to be expected from stock springs...the ride is very stiff. Any ideas?
