FAQ
Will this require tuning or emissions deletion?No. This is a DPF/Filter-back system. It installs after the emissions equipment and does not require tuning.
Does S6168AL fit coil-spring rear suspensions?
No. S6168AL is specified for leaf-spring rear suspensions. Verify your truck’s rear suspension before purchase.
Is this system stainless steel?
No. S6168AL is the Installer Series (aluminized steel). If you want stainless, look for the Armor series part numbers.
