question on lift
I put the springtech lift on my son's truck and he is running 35s on stock rims. Also I did not use a spring compressor to get the old springs out and the new ones in. I just pried the lower control are down and pulled the spring out. Then pried it down again when putting in the new lift spring. No problems at all.
I have 35s with the springtech and only minor rubbing on the passenger side frame rail at full lock, but my frames also a little bent so it had to rub there some to be aligned correctly.
What Motor and gears do you have. If you have 355s you will not want to go to 37s without regearing. My kid's truck lost a lot of power going to 35s. I could not imagine going to 37 with 355s. Also think about the wear on the transmission.
If you go with 4.88s your highway mileage is gonna suck until you get something bigger than 35's. Cause right now with the stock 3.55's im pulling about 12 to 14 highway and averaging about 13 overall. Your gonna be worse than that with 35's and 4.88s until you go bigger most likely.
