Review of a Trailer Suspension Enhancement System - TASR35HDS07 Video

I have another option for you, but the only hub and drum assemblies available with the 6 on 5-1/2" bolt pattern are only rated for wheels up to 16-1/2" diameter and are not designed to work with 17" wheels. Starting with…

I'm assuming you're speaking of the clearance between the top of the tire and the fender/wheel well. Four inches of clearance between the tire/fender and two inches clearance to the inside is what we typically want to see, but 3…

It is best to measure your leaf springs with the trailer weight off the spring. As you mentioned you have a measurement of 26.5" from eye center to eye center you more likely have the 25-1/8" Spring #e54SR. If this spring was…

We actually have a version of the Timbren Axle Less kit for 3,500 lb axle replacements that has a 4 inch lift built into it with the part #ASR3500S06 which would work great for you. It does not have hubs or brake assemblies though so you'd…

When you say Timbren 3,500 setup I believe you are referring to the Timbren Axle-less system part #ASR3500S06. The mounting bracket is 4-3/4" wide. I have attached a couple of diagrams of the Timbren system for your reference.

The only real difference between the Timbren Heavy-Duty Axle-Less Trailer Suspension with 4" Lift Spindle - 3,500 #ASR35HDS05 and the standard Timbren #ASR3500S06 is that the Heavy-Duty model features a larger spindle that would…

We have versions of the Timbren Axle Less systems like what you referenced for a 3,500 lb axle that have 4 inch lifts built into them like the #ASR3500S06.

The Timbren axle-less suspension kits are offered in either 4-on-4 or 5-on-4-1/2 bolt patterns; none is available with a 8-on-6-1/2 pattern idler hubs. All such kits are shown on the linked page. Several of these 3500-lb kits, parts #ASR3500S06,…

Your trailer is equipped with a Lippert 3,500 pound axle that has a 95 inch hub face length and a 76 inch spring seat length. The closest replacement axle we have available to these specs is the Dexter Trailer Axle #7359765-EB that features a 95…

Looking up the information for your 2021 KZ Sportsman 301BHKSE I see that they use axles rated for 4,000lbs. For this we have either the 26" #e48SR or 25-1/4" #e93SR leaf springs. You will need to measure the springs on your KZ to…

There will be no performance issues whatsoever going from leaf springs with 4 leaves to leaf springs with 3 leaves. So long as you have the correct length, the springs are going to work superbly. The 3-leaf, 4,000 lb leaf springs we have measure…

The 3500 lb Timbren Axle-Less suspension kit #ASR3500S05 would be a good choice. The spindles provided with the #ASR3500S05 would indeed be compatible with the bearing set provided with the #AKIHUB-550-35-K idler hub, but since the Timbren…
