First of all, sorry if the question is too basic, but I'm just starting on it. I have my KRX for about 3 months and my back suspension sagged about 1 1/2". I read the manual and saw that the adjustment measuring from bottom to the top of the spring should be between 28.96 and 29.09 in. I lifted my back tire from the floor and measured the spring length from bottom to top and it is at 24 in. How can that be possible? Should I move it up almost 5 in?
Any help will be greatly appreciated.

here is not the best copy of the shock section in the manual that gives you the idea of where to measure from and what the stock specs are.. start with tires aired the same on level ground and roll your Car back and fourth so it settles level.. take the measurement while on the ground all of them and write it down.. raising your car takes the tension off the springs to make adjustments easier but all measurements must start on the ground.. most guys on here have posted as well as myself that there near the end being able to adjust anymore to still have the crossovers work with out spring lock and can't get near 12" of ground clearance.. So I gave in and just ordered up a new set of springs from Shock Therapy.. If you do a search there are a few postings on the subject.. hope this helps

Thank you. I looked at the manual and my rear shocks wee at 24 in. I tied a little more, but only got to 13" clearance. I'll probably need to work on new springs too.

If you are measuring the rear shock per the Manual I just sent than 24" is simply not possible.. the max spring pack measurement is 28.5" this spec is given to avoid spring lock... if you have some how ran the adjuster down an additional 4" beyond this .. you may cause some damage to some suspension attachment points.. Adjust the shock springs to the given measurement spec's if you do not get the right ground clearance... then get rid of the over load if that is not the problem then new springs maybe needed...

How do you like the Shock Therapy springs? Did you get their crossover rings also? My front springs are noisey, not talking about hitting the crossover rings, just a spring noise if you rock it back and forth. I hear the same on the new one on the showroom floor, but my buddies does not do it. Did your have this noise and do the ST springs make the noise?

I'm waiting for shock therapy spring kit to arrive should be here in a few days.. I also ordered there crossovers that have an o ring in them to stop the slapping sound some hear..

Just my opinion but the way the manual says to measure for shock adjustment seems confusing and makes a simple job a pita. Ride height should be set by measuring from lowest point on front and rear of skid plate to the ground. I run 14.5" in front 14" in rear. I set my crossovers by measuring the gaps in the top/small spring, add them together, subtract 1/8" and set crossovers to that measurement by measuring from bottom of crossover to top of spring spacer. I have seen many KRXs on the trail and not one has has the crossovers set correctly from dealer. They only use about 40% of the top spring. Just my 2 cents.

Agree one would think the top spring would be of the right spring psi and size to utilize all of the travel.. I found out one of the reasons to adjust this out is to eliminate excessive body roll.. by using the factory measuring technique gives a base line starting point to which one can make measurable change.
