So I'm trying to install some aftermarket bumpstops that fit between my axle and frame but I need about another inch of clearance to squeeze them in as suspension is too compressed right now. I don't have a jack but I need to unweight the suspension on the rear just enough to get one more inch of clearance. I guess I could run my tank dry and take everything out of the van and maybe get that but I was wondering if there was an easier way to maybe just get another measly one inch of clearance. One side at a time is fine. Any ideas?
