Default Just put on 275/65R20 K02's on my +12mm wheels and they rub badly on the bumper crash

bar and on the felt liner at the rear of the wheel well. Does anyone else have this size tire and this offset wheel? Will a 2" spacer fix my issue? Will I need a larger block for the rear to keep some rake?

I placed a floor jack underneath where the control arm attaches to the frame and jacked up 2 inches and the tires barely touch the front. At 2.5 inches it clears it. Can anyone tell me if this is a reasonable way to determine the amount by which I need to lift the front end?

Also, I've never had a leveling kit. Does it hurt the ride? Should I go with a coilover instead? A gentlemen over at Stage3 suggested I consider the Fox 2.0 kit, but I'm worried that I need that extra 1/2 inch. However, I don't know that my testing method equates to what will happen when I add the spacer or coilover.

Sorry for all of the questions, I'm a suspension mod noob.

Thanks in advance for the help! I need to order parts soon as the rubbing is unacceptable.

No spacer, I think you meant lift

Spacer will make it worse

2" lift should be fine

Thank you, yes I am referring to a lift.

Anyone else with thoughts on this? I'm trying to avoid wasting valuable install $ on something that won't clear, but also not overspend on parts I don't need.

I'd also appreciate some input on my other questions.

I might have some answers for you next Friday. I have a KO2 275/65/20 tires on stock rims but I'm adding 1.5" wheel adapters along with a 2.5" front spacer and 2.25" rear block (currently has no rear block-4x2). As of right now I have no rub with the tires and stock wheels. I'm curious as to whether or not the 1.5" adapters will change the geometry enough to rub.

I hope to have my own answers by then. I'm going to suck it up and likely do coilovers, rear shocks and taller block...just have to decide which kit.

My truck is a 3.5L eco Lariat Sport. I'm glad to hear that the level allows for that size! Thank you for the reply! Now I'm wondering if 2" is enough because I'm thinking coilovers rather than a level. The FOX 2.0 kit only goes to 2"....

The problem is the +12.

I put 275/65s on my truck with a 2.5" level kit and they fit just fine. I added some 1.5" spacers to get some poke with the wheels and now it rubs, but only on counterclockwise reverse and just barely on the crash bars.

I think you'll be fine with that offset it you level the front 2.5". It won't matter if you use a coil over or a strut "spacer" to get the height.

Yup, that's what I've noticed/thought. In your opinion, do you think it would rub more with a 2" lift or would a 2" suffice?

I think I would go 2.5" but there's still no guarantee. I don't know the math on the offset. My stock platinum rims are a +44 and I have 1.5" spacers on the rims. I'm sure there's a way to calculate a +44 with a 1.5" spacer is a xyz offset.
