Nice! I'll pass this along to Tanner. I wish this wasn't how you had to work the system, but these days, you just have to get it wherever you can find inventory. We're doing our best to keep up with demand and get you guys product as quickly as possible. We are looking at this DAILY and doing our best to provide answers and customer support wherever we can.
The 250lb rear spring is a great balance of rate and comfort with a range of adjustment that works in your weight range. You're on the right track.
The load leveling system in the rear uses a different spring, but the same rear shock. So you could remove all the front and sell that and the rear lift spring separately, or remove the entire kit and do the Stage 2 with Load Leveling which includes rear shocks. My thought is that you'll get the most back in the used market with a complete kit rather than a kit missing the rear shocks. If you can wait until the end of the year, our Resi rear shocks will be available.
