Question:

Hello, I’m noticing my trailer is leaning towards the driver side and after measuring is about an inch and 1/4 lower than the higher side. I’m thinking it’s time to replace/upgrade the leaf springs. Question is can I replace the leaf springs with 2 different weight capacity’s? Like put a stiffer spring on the heavy side of the trailer? Or is it better to keep the two sides identical? 2018 coachman clipper 17bhs

You definitely want to keep the same weight capacity leaf springs on both sides; having different capacities will cause uneven wear on the tires and other suspension components. Your 2018 Coachmen Clipper 17BHS will have a 3,500 lb axles, so to determine the correct replacement leaf springs you'll need to measure your current leaf springs from center-to-center of the spring eyes.

Leaf springs also flatten a bit over time, so you should go with ones that measure a bit shorter than what you currently have. For example, if they measured 26-1/2" go with the 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 27" Long # e97SR.
