Hi I have done a little bit of stress testing to make sure it will hold up. at both ends of the travel the rack ether hits the casing or the spring comes under full compression, as well as that if you look closely at the pinion you will see it has little lumps on the side of the rounds, this is to stop the end of travel causing extra stress on the last tooth on each end. I have tested it with about 5-600 full movements but i have also done some testing with extream forces, eg i got a 6lb hammer and hit the crap out of the end of the trailing arms, this bent the trailing arms but the R&P teeth held up fine. :) At the end of the day if they do fail its only 1 min of cutting to make a new pinion out of 10mm Aluminium and about 2.3mins to make it from 10mm Stainless Steel or the like :) Grant
