Default "I need one more inch"

And it ain't no "that's what she said" joke.

My 2019 extended length passenger van is sitting about 1 inch higher than my garage door header. I originally wanted to park it in the garage during winter. Thinking about it over the last week, I thought there could be something done to the rear leaf springs to help lower it that inch. Stopped by a spring shop near me yesterday and the tech said he could "de-arch both rear springs" with option of adding in 1 additional leaf in order to prevent a "sag" when towing. He said de-arching won't reduce the spring capacity, it will just flatten out the arch, so a loss of 1 inch of suspension travel. Adding in another leaf will strengthen the spring pack in order for the van to be level while towing. The shop has done it many times as many owners request it for the same reason: garage clearance.

Anyone have thoughts or done this? Would loose about 1" of the rake while empty.

Smaller tires? Other then raising your garage roof or course. That would not be cheap unless you are good at carpentry.

Let a bit of air out the tires, reinflate when ready to drive again.

id say problem solved with this one lol. Won’t cost you anything but an air compressor or tire inflator if you don’t have one already.

As an added bonus it will force you to make sure you have the right amount of air in the tires before you drive it.

LOL! It's funny as I once said I thought tire pressure monitors were as waste of time. I'd still use the feature. Then a few weeks back I used it, and had a small leak going
on in my left rear tire. It was 26 PSI and I always run 35-36 PSI. Sure enough I had a small nail in the tire. Needless to say I will keep the TPS system going in my 2015
Malibu..

It's only your rear that's too high? Yall are only talking about leaf springs. If everything else is good drill another hole in your shackles or have machine shop make you shorter ones
