Hi Neil, I am pleased to assist you. These SumoSprings are primarily designed to assist with squatting when towing a load rather than significantly lifting the trailer's ventricle. While they can provide some lift—typically around 1/4" to 1/2" when installed with the proper preload—their main function is to support the trailer and prevent excessive squatting when carrying heavy loads. If you're interested, you can use the link below to order while the part is in stock. Your order will come with a 30-day post-purchase price match guarantee. I hope this helps, and enjoy shopping! https://www.carparts.com/helper-spring/supersprings/s99tss10647?can=CPGG4850_CSQA_20241203
