The additional down travel provided by an ICON Vehicle Dynamics 2020-Up GM HD 2500/3500 suspension system can cause clearance issues between the sway bar and the stock splash guard as the suspension approaches full extension. Upon identifying the weakness with the OEM splash guard, ICON's engineers developed a heavy-duty unit to replace it with and eliminate the need for trimming the OEM unit. ICON's splash guard kit is constructed from 1/8" thick CNC laser cut aluminum and features a durable semi-gloss black powder coat finish.
