That's what's great about Denny's system you can set your ride height dead on to where you want it to be from low to high Spindle height isn't the only deciding factor on ride height between the 3 shocks Denny suggest using there is 3" difference in ride height QA1 DS401 - DS403 and DS501 one of the problems I had to overcome on the HDK was to stop thinking STOCK because it's not your getting into "HOT RODDING" and there is no cut and dry answer when doing that because every body want's a different result you have to rely on experience and trial and error all anybody can do on advice is to get you in the ballpark be it right or wrong that's up to what you want your not turning a bolt to raise and lower the front there's a lot more to it than that but if your a true "HOT RODDER" the fun part is doing something different and figuring it out then standing back and say look what I did anybody can do "STOCK"
