Redline Trailer Suspension - Leaf Spring Suspension - APUBR-9 Review Video

Each of the leaves on the Leaf Spring #e47SR are 3/8" so this will give the spring pack a height of 1-1/2". Here is a list of our U-Bolt Kits for a 3" axle. Redline #APUBR-9 Dexter #APUBR-8 CE Smith #CE23003

The 7 leaf spring part #DX74XR that you referenced can be used in under or over slung axle configurations. Leaf springs aren't made for either style and can easily fit both. It would be just a matter of going with correct u-bolt kit for the axle…

I can help you determine the right replacement double-eye leaf springs for your 2019 Grand Design Reflection 230RL, though we don't have any way of knowing what specific ones you need. It's pretty easy though, as all you need to do is measure…

Hey Doug, the #8-213-5UC1 hub that you mentioned uses only the #25580 inner and #LM67048 outer bearings. The #25580 bearing has a 1.75" ID and roughly 3-1/4" OD. The #L68149 bearing has a 1.378" ID and roughly 2-3/8" OD. So, there…

I checked with CE Smith and you will want to torque the 1/2" bolts of the U-Bolt Kit item #CE23003 to 65 ft lbs.

You will have to do some measuring. Take a look at our Double-Eye Trailer Suspension article (see link). I have also linked a picture of a shackle link showing where to measure. Measurements for replacement 1) Measure current shackle from center of…

The best way to measure a trailer spring for purposes of selecting a replacement is to remove it completely from the suspension. It is also important to note that leaf springs will tend to elongate over time as they wear. You might pull a well-worn…

The 6-Leaf Double-Eye Spring for 4,500-lb Trailer Axles #e27SR are going to be the closest leaf springs we have for your 2012 Jayco 23.5 travel trailer. These springs have the same 26" measurement. While these will help to raise the height lost…

The arms on your Fastway e2 Weight Distribution System #FA94-00-0800 can be removed by either pulling on the keeper tab to release them, or by swinging them outward to be perpendicular to the tow vehicle. At this point, the arm should drop freely…
