rear spring rates
Hey all, does anyone know the factory spring rates for the rear springs on an 05 softail deluxe? has anyone tried the springs from LA Choppers to beef up the rear suspension? how does it affect ride and height if you have? Ralph

Can't answer your specific question but I can share my personal experience with the Deluxe. A riding buddy gave me his 08 Deluxe to repair and make modifications. One of his complaints was that the bike sat to low for our riding terrain. He consistently scrapped the floorboards or bottomed out and wanted to raise the height of the bike.
After much research, I determined that the only difference in the height of the Deluxe as compared to the Heritage or Fatboy were the rear shocks. The front forks and fork springs were identical on all three models. The shock canisters on the Deluxe are a different length which provide the lower rear stance. As an experiment I installed a set of (stock) shocks from an 02 Fatboy. The Fatboy shocks raised the rear of his Deluxe roughly 1.5 inches. After a few road test to dial-in the spring preload, he stated that the bike rode and handled better than with the stock Deluxe shocks.
If your suspension is not providing the ride comfort or handling control you desire first try re-adjusting the shock spring preload. However, due to the design of the Deluxe shocks I believe your best solution would be to install a set of Progressive 422's which would give you the ability to adjust both height and preload.

i like the way it handles i just want a bit more spring rate in the rear to help when shes loaded up and when i really get on it. 422's be nice but not in my budget this year because i really need a set of rims.
