Can damage occur installing heavyweight coils before adding front & rear bumpers?
 
Hello all,

Probably a stupid question, but I was reading something on a vendor website I bought my OME coils from and it mentioned not to install if you didn't have extra weight or damage could occur.

I ordered bilstein 5100's for front and back a diff drop, and OME 2883 & 2891 springs for heavy weight as I will be installing a front and rear bumper.

Thing is, my bumper isn't set to ship until April. I wanted to go ahead and install my lift/wheels/tires but it sounds like maybe I shouldn't before getting my front and rear bumpers on? Any truth to that?

Thanks for your input.

Not really, it will ride a little stiffer until the heavy bumpers are installed, but watch your tire pressure and you should be fine.

This is a nonissue. You’ll be fine.

I hope the 2891s treat you well. I ran them for several years and just added a swingout; I can already tell they will sag when I load up with gear for an outing.

I’m probably going to add airbags to them because I don’t want any more lift on my truck.

The only way I see damage occurring is if you shock coil plate is about rusted through. The extra heavier coils could bend those. However, 6 months or a year later they would have bent anyhow. Its probably why there is a disclaimer on them. Someone's frame was rotted and blamed the newer springs. No way could stiffer springs do any damage under normal conditions. Just a stiffer ride like the other users suggested. :)

The bilstein and heavy spring combo will ride stiff with no weight but will be perfectly functional. You'll need to make sure you don't over-extend the front suspension, and the perches on the front shocks may need moved up once you get weight on the front end.
