What lift required for wheel spacers?

Finally put a set of 265/70/17 tires on the truck this past weekend (Terra Grapplers). They're mounted on the stock 17" sport rims but can't believe what a difference this makes to truck, it actually looks like a truck! The stock Dueler HT's look like slicks in comparison to these tires!

My truck is on the stock TRD sport suspension and I'm interested in a set of Spidertrax spacers but I understand that without a lift this will cause the tires to rub. My question is whether a 5100 leveling (i.e. set to 1.75") would be enough of a lift or whether I'd need to go 3" + to avoid the rubbing issue?

I was considering a pair of adjustable 5100's but not looking to do a full lift kit b/c I park underground during the workday and the truck wouldn't fit.

 

honestly if you are set on getting the wheel spaces i would just buy them and test fit them. then move into the adjustable shocks if needed or wanted

 

You don't "need " a lift...they might rub a little plastic...easily trimmed...I'd look into 5100 shocks for the front

 

Great, thanks guys. After going back and forth on various lift options I think I'll stick with the 5100's upfront @ 1.75" then think about spacers after.
