My father in law has a honda 400 foreman that serves as his legs, he is a disabled firefighter and needs to get around his farm to chore. He weighs in at just under 300 lbs, and the rear wants to bottom on him at any kind of speed when he hits a bump. he was wondering if there is a heavier spring available, or what the factory spring rate and length was on the rear sping as I can get eibach springs at a good rate (I am into rock crawlers, have a coilover supplier). If I knew the factory length and rate, I could bump the rate up a bit and install for a little bit of nothing.
thank you in advance for all you help

a high lifter spring increases weight capisity an extra 100 pounds.( more than NEW stock springs). i think ther only a round 30$$ a piece! order one for the rear or three for all the way around! it should help a lot! they also sell the tool to put the springs on! i think you can get the whole kit for 125$$. i think!
