Question:
Hello! I have a 2018 Venture RV Sonic Lite 167VMS travel trailer and am looking for leaf spring replacements. Im looking for a small weight rating increase from stock on the 4,000lb axle. Wondering if youd be able to point me to the right parts needed. I would like to replace the U bolts as well. Thanks in advance!

Hello Cody, I can definitely point you in the right direction. When replacing leaf springs, the replacement springs must be identical in length to the current springs. So the best way to determine the correct replacement will be to jack up one side of the trailer and measure the center-eye to center-eye measurement of the leaf spring when not under a load. It may be possible to go with a higher rated spring, but it will all depend on what options are available in that specific length. If you want to take that measurement and post it in the comments below I am happy to make a recommendation.
For a U-bolt kit I suggest going with the CE Smith U-Bolt Kit # CE23002.
