I have had nothing but good luck with downey springs..I have beat the piss out of the old ones I had..Good ride,good flex and seem to be with in budget range..I used my old downey springs to aide in the build up of my front hybrid packs and I am very happy with the out come..I don't think allpor rear springs are that great..I have seen them flex and on a truck I think a better pack can be built and for alot less money..The allpro pack seems to do pretty good on a 4runner though..The added weight makes a big difference I think..A truck with flatbed and some gear just does not have enough weight to make them work I think..As for the rear I have seen ranger,mazda and 89-95 toy rear springs do the best on lighter weight trucks..
