YES. I bought my deavers new and initially they were a bit stiff actually. Then I put my toolbox and fullsize spare in the bed and they ride great. Couldn't ask for better. Just don't expect super flex outta them. They are nice but the 63" chevy springs will still out do the deavers.
deavers are awesome, period. find out if they are the prerunner pack or the race pack. The prerun pack is a softer rate than the race pack. The race pack is designed for the weight dual spares, fuel, tools, and what not.
