I have been looking for a more versatile spring that will perform the ability to have a plush ride while empty, but have firm stability when loaded down on family trips. The OME 860 coils I had gave a big stinkbug while DDing around town empty then when loaded with only kids, Ice chest & misc. items it would start to squat.
After doing a lot of research I learned of springs that have two spring ratings rather than one, they call them dual rate. It turns out Old Man Emu has two to that will fit the 80 series. The 866 would be way to firm for my needs having a rating of 240/300 lbs. The other is the 862 with a rating of 170/260. 170lb. is the factory spec for the 80 series & 250lb. rate is what OME uses for the heavy 863 spring.
What does this mean?
A 170/260 lb. rating means plush/firm.
Now that I have broke them in a bit loaded & empty, they are just what I wanted. They have helped Lexi450 have even better turning manners. I can feel the plush 170lb. rate while empty, they feel very nice. When I make fast hard turns I can feel them set into the firmer 260lb. rate & it turns like it's on rails. I can't be happer.
To note: these are considered to be stock height replacement springs that gives approximately 1" lift over stock. To achieve a 2" lift I added 40mm to them giving a final center hub to bottom of flare of 22" after minus of 1" for my body lift (Stock is approx. 20").
If only OME would only add one more turn & .5mm thicker wire to the 862 it would increase lift by 1" like they do to the 850 & 850J. They could call it an 862J.... Hmmmm, just having fun.
