Most of the load carrying strength of these frames is in the lower flanges. I don't like the way significant size holes are drilled in the lower flange of the trailer frame I beams. This is the motion direction that (theoretically) needs to be damped. Of all the kits, I do like the way the Joyrider product gets the damper as vertical as possible. I was surprised to learn from Sonny that the exact same damper is used on all Joyrider kits, regardless of sprung weight, unsprung weight or damping expectation. Corvette on one end of the scale and (old) Cadillac on the other end of the scale.
On a car/truck, both jounce and rebound rates are tuned to the specific expectations of the vehicle. I had the opportunity to discuss the Joyrider system with Sonny Dismuke (designer of the Joyrider product) at a Grand Design Rally, a few years ago.Īs you mention, I have some experience in damper tuning. This was high on my suspension "wish list" until I researched it a bit. I didn't chime in on this because you were specifically looking for feedback from those who had installed dampers (shocks). What do you think about Lippert's mounting strategy?Hi Jim, I'm sure lots of folks are going to be interested in your I know you have done some shock tuning work in the past. My 315's 10,995 is probably the lowest GVWR for something as robust as the IS, especially considering the cost.īottom line: you'll be the shock pioneer for the Imagine crowd. JimAs I was doing chores it dawned on me that you had an Imagine-the IS would be overkill for that trailer (7850 GVWR). My rig rides great but on those sinusoidal roads, this vertical motion of the trailer can be a PITA. For my Imagine, I have a fairly soft suspension and rather than move to heavier springs as in the new models, I'm thinking of adding the shocks to help stabilize that vertical motion. This damping can smooth things out as the coach moves in the vertical direction. This also applies with wheel balancing, but I do it. Rarely do the wheels leave the ground on a trailer as in a auto or truck due to such heavy loading. For these heavy rigs, the issues of not having shocks differs from autos. I'm sure the use of shock on the IS helps a great deal. From your pics I see MORryde uses shocks with their IS system.
