Gunnar Offroad products are for off-road use only. Our warranty covers manufacturing defects only. We do not warranty anything installed by an outside company or person. Not all welders are created equal and everyone has "a friend who knows a guy who welds." Don't use him to install your suspension. With that said, we do stand behind our products 100% when installed by us or an approved company. No returns will be accepted once a part is installed on a truck. We will accept returns that have not been installed for a 25% restocking fee. Cancellations will also incur a 25% restocking fee, unless the cancellation is initiated by us. The warranty only applies to hard parts, meaning parts welded by us. Warranties do not apply to wear parts, meaning parts intended to be periodically replaced due to wear, moisture damage, or off road damage, such as (but not limited to) bushings, uniballs, uniball pins, heim joints, rod ends, snap rings, bolts, nuts, washers, etc.
