Hi there Bob Dirt! Just bought a new Sunseeker 2400W and getting ready to install front and rear SumoSprings. I see where you just used your rear stabilizer jacks and a 4x4 block to lift the back end enough to slide the rear blocks into place, is that true? Doesn't look like it needs to come up much, but figured I'd have to lift using a small bottle jack. Don't want to risk damaging the rear stab jacks, but if they're strong enough to do the job, I can see where it'd save a lot of time. Can you pls confirm? Thanks!
