This last Saturday I helped install some Ladder Bars from Glacier Diesel and boy are they slick. The Truck is a 05 with Scheid Twins, TST, SMARTY, a bunch of other stuff and talk about pin you in the seat. It did it before, but now, it's crazy... There super easy to install, took all of about 40 mins taking our time. There super heavy duty and ya'll know the saying, you pay for what you get and these are awesome. I have rode in this truck for many miles going places and even up to VA for the East Coast Truck Nationals and the ride quality is 100 times better... For anyone looking to save their drive train some wear and tear and get a really nice ride, no hopin up and down in your seat goin down the road over un even pavement, these are the way to go... I'll be ordering mine after the Holidays... :-laf
