I'm not planning on towing, but I'd just like to keep the option of being able to toss things in the bed when I'm in town, which these 2+1's should be perfect for. Still planning on Caltrac's with these however.

Rick, what size rear tires are you running with your setup?

P295/50R16s, on 9.5 x 16" Centerline "Fluted Telstars". The backspacing wasn't great till I traded my one side shortened 8.8 housing and axles to a customer I had done another 8.8 for, for a Toyota Cressida, which was shortened on both sides, making it like 53.5" instead of 54.75". He didn't measure correctly and it would up too short, but perfect for my truck with these particular wheels.....the only way they could be better would be if they were 15"s instead of 16"s, 16" P295s are HARD to find.

I can imagine. I will have a 53.5” 8.8 under my truck as well, but I’ll be running 17x8 rim at all for corners. I think the most I’ll be able to get away with is 275/40r17s. Apparantly guys have gone as far as 315! But that’s a little ridiculous for an 8” rim IMO.

The results are in! I got a chance to throw these Astro springs under the S10 tonight. They fit perfectly and do indeed give it a drop, but the result was a little underwhelming. Comparing the springs side to side on the floor, there was an easy 2-3" height difference between the spring pad areas on both sets. But once they're on and the truck is sitting on the ground, it only gave it slightly more than a 1" overall drop. I think if I would've started with the 3+1 or 4+1 spring pack, I probably would've seen a greater difference. I might also see a bit more with the engine and transmission installed, but I'd bet it wouldn't be more than 1/4-1/2". Oh well, at least they were free and now everything is nice and freed up to installed a set of real 3" springs! :thumbup:

You can always relocate some weight too. My Optima battery is at the right rear, under the bed, bolted TO the bed, upside down. Got a spare and a jack? Bolt them on back there too, :thumbup:

Do not measure to the ground. Measure to the bottom of the wheel, this eliminates the tire. Pressure and wear can make a difference.

Drive it a little bit and see if the springs settle

I’m just going to go straight for the Belltech springs. I think that between those and the larger 8.8 rear end, I should probably end up where I want to be height wise. If not, I can always add in the 1” block.
