Review of Redline Trailer Leaf Spring Suspension - Hangers - Suspension Kits - HAP-105-205-01 Video

There isn't a specific distance the hangers have to be for hanger kit #AP216-H238. A good place to start is 30-1/2 inches on center but you would only really know by mocking it up on the trailer before permanently installing the hangers. To…

Yes, going from a 4 leaf to a 6 leaf spring would add slightly to your ride height. For example, if the current 4 leaf spring has 3/8" thick leaves, and you go to a 6 leaf spring with 3/8" thick leaves, you would be adding 3/4" of…

The Easy Grease Trailer Idler Hub Assembly for 3.5K Axles part #AKIHUB-545-35-G-EZ-K is a direct replacement for a UFP H-1377.

If your trailer has torsion axles, no worries but it it's a leaf spring suspension you really should have equalizers. Without the equalizer, the trailer will have a rougher ride and the weight won't be balanced across both axles when going…

The UFP H-1377 correlates to a Dexter #84 spindle, which is for a 3,500 pound axle. This will utilize an inner bearing #L68149 and an outer bearing #L44649. As this is being used on a boat trailer, I highly suggest going with the etrailer.com…

We don't carry the 2x2 inch square axle in that length. We carry the Dexter Trailer Axle Beam with EZ-Lube Spindles - 89" Long - 3,500 lbs #T3584F-EZ-8974 which is the comparable round axle which will work just fine. You simply will use the…

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.

Do you by any chance mean 235/80-16 and 235/85-16? Because there isn't a 275 trailer tire size that I have seen. If so then the widths are the same between the two 235 sizes. The difference is overall diameter. The 235/80-16 is 30.9 inches in…

I checked with Dexter, manufacturer of many trailer parts, and according to them there should be at least 1 inch of space between the tires when under load. So once your trailer is loaded and ready to tow, if you have more than 1 inch of space…

The difference in tire diameter will be an additional 2-1/2 inches going from the 225/75-15 which measure 28.4 to the 235/80-16 which measure 30.9 inches. As a general rule of thumb the minimum safe distance between front and rear tires on the same…

Thanks for that excellent info, and we do have an option for you, though the Dexter E-Z Flex #K71-656-00 actually has two different size equalizers, one that is 7-1/4" long and the other that is 5-3/4" long (from bolt hole to bolt hole) so…

The Lippert Components Center Point by Trailair Air-Ride Suspension Upgrade #LC1565391 referenced in your question will work very well on your tandem axle Forest River Surveyor Trailer. This will provide you with an extremely smooth ride and improved…
