Product Questions & Answers

Q:Do these lift the ventricle any or just assist with squatting when towing a load? Show Less
Neil D.
A:BEST ANSWERHi 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 Show less

Q:lift kit for 2003 Toyota RAV4 4x4 ?
woodz07
A:BEST ANSWERHi Joseph, thank you for reaching out. This set of helper springs is incompatible with the 2003 Toyota RAV4. This item is designed for trailer frames. Per checking, we don't have a suspension lift kit for your vehicle. Thank you for inquiring. Have a nice day. Show less
