Henderson Lineup was recommended by Tiffin Motorhomes. My 2018 Tiffin 36LA 24k Ford chassis had a lot of sway left to right and bounce forward when braking. Also, the steering wheel had 3 inches of play each direction. Henderson Lineup removed old shocks (4) and added 8 Koni shocks, two per wheel. They removed the Sumo Springs that Tiffin had originally installed. Next, they fine tuned the steering linkage, centered the steering wheel and installed a safe steer shock on the steering rod. When I left the store and headed home that included driving down a 5 degree descent for 8 miles, the motorhome hugged the road and the sway was gone. Breaking didn’t send things sliding forward or falling off the dinette. I am amazed how much safer I feel driving my Tiffin and enjoying the drive. The steering wheel has no play so my hand and arm are steering like a SUV. Matt, the technician, was very helping in explaining where the parts were to be installed and had me join him in the pit to see for myself. Matt and I went on a pre and post test drive to compare the drives. I highly recommend Henderson Lineup and glad I drove the 5 hour drive to get the work done. David C Happy Valley Oregon
