thought i would add that the rear springs are too weak and sag so i use air shocks to help the back out when i am loaded down with supplies (they also leak if you are hauling ass down a bumpy steep downhill but it lowers your center of gravity in a pinch so i like it that way) but for the front the calmini shackle reversal springs are great and can land fine from 3 feet in the air with the exception of the axle many many times over without loosing their arch or eveness from left to right.
calmini on the other hand, thats another story. those spua skid plate thingies are complete crap and when i bought my kit one had the holes crooked but calmini wouldnt replace it unless i sent it in, they evaluated it and then if they determined it was bad they would send me a new one. the turnaround estimate was 3-4 weeks for this process so i just threw them away and put the stock ones back on. i also bought their 4.5? to 1 gears for the t case and they got chipped up after 100 miles. yes i ahd new bearings and yes i know what i am doing, i am a mechanical engineer and work often in our machine shop so i know their tolerances were sloppy on the set (granted its been a few years since this happened, hopefully they have gotten better) i called them to talk about it and eventually talked to one of their engineers there and he was very defiant that their part could have failed and was a real cock about it so i do not buy anything from them any more, i like trail tough and their service dept, theyre the most friendly people around for sammi parts.
