i tow a 6000 lb boat on a very regular basis over the summer. the truck performs beautifully. it does as well as the 2002 V8 sequoia my parents drive, except the taco feels more stable while towing. so i know that the truck can tow great, but my question is...i want to put a set of spidertrax wheel spacers on it, but i'm worried that the extra length will put too much force on the ends of the axles when i'm towing such a heavy load. the last thing i want is for my wheels to break off when i'm towing a boat down the road at 70 mph. would wheel spacers compromise the trucks axles/other wheel related components, or compromise my safety?
i appreciate any input
