Mossey No, the only spring they make for these axles is the 2750 pound version. I changed out our original 5-leaf springs for the Alcans and I honestly can not tell any difference in the ride or the handling. Tali did most of the towing during our recent 5000 mile trip up to Maine and she said she could not tell any difference either. 2 4 Steve, Tali and our dog Rocky plus our beloved Storm, Lucy, Maggie and Reacher (all waiting at the Rainbow Bridge) 2008 Legacy Elite I - Outlaw Oliver, Hull #026 | 2014 Legacy Elite II - Outlaw Oliver, Hull #050 | 2022 Silverado High Country 3500HD SRW Diesel 4x4 Link to comment Share on other sites More sharing options...

I suspect that they could. But as you noted, I too am wondering. Their, and about all 5 leaf springs are made for stiffness by the extra leaf. The weight of the steel is a good indicator of the weight bearing capacity. The initial ALCANers were asking for a 2,000 pounder and were mis-informed as to the true capacity and stiffness of their product. When I saw the ratings jump of almost a thousand pounds per leaf (1750 to 2700) my red flags went up. That's how I got to the Dexter capacity upgrade of the PB4 from the PB4B. One thing to keep in mind is that ALCAN's speciality is off road applications. Their focus is not on an easy ride for the load, but surviving punishing situtations encounted by the Baja and Mountain Racers and those inspiring to be. Hence their recommendation. Per several experts that I trust, this is way over-sprung for general use for the majority of the OE2 Fleet. But on the other side of the coin, it may be a good choice for those super heavy or more serious off road users, Expecially if they have experienced whitness marks from banging of the axle U-bolts against the subframe. Those owners need a 5 leaf. Point is this is not a good/bad discussion. It is all about each owner's trailer weight and use.

Moderator+ ScubaRx Posted July 21 Moderator+ Share Posted July 21 (edited) 20 hours ago, John Dorrer said: So would the 9/16 equate to 3" axel? All the U-Bolts supplied by Alcan have been 9/16". The OEM's (at least on mine) were 1/2". It is very important, if you buy the Alcans, to know before placing your order the diameter of the axles on your trailer. Most will be 3". Some of the earlier builds will have 2-1/2". One owner told me his (used) trailer had one of each. This, most likely, was from one having been replaced prior to his acquiring it. I'm not totally confident in the report that one owner said his axles were 2-3/8", but who knows? Measure them to know for sure. If you don't have a caliper or a micrometer or don't know what these are then you may have to result to the string method (but this does require some math.) You could use a C-Clamp as a poor man's micrometer. Just tighten it up on the axle just loose enough so it slides off, then measure between the jaw faces of the clamp.

Lew just sent me out U-bolts that were 1/2 in. for my 3500 lb axles with 3in tubes. The only problem for me is if the replacement U-bolts are 9/16, I will have to drill out the U-bolt plate so they fit. Easy to modify. Bottom line and the reason I first posted about the U-bolts is to point out to be sure you measure your axle diameter or get your spec sheet from Dexter before ordering.

rideadeuce Posted July 24 Share Posted July 24 (edited) So got the new U-bolts from ALCAN and put the new leaf springs on only to find out the HD 1/2 in. OEM shackles were too short. They are the HD 1/2 in width but 2 in long measured zerk to zerk. The 2nd leaf rides on the suspension arm. Talked with Lew, figured out the problem and he is sending out new 2 1/4in HD shackles to resolve the problem. Confirmed Key points: 3500 lb axles use 4 bolts on the backside of the hub and 1/2 in. U-bolts. They can have tube diameters of 2 1/2 or 3 in. Make sure to measure. 5200 lb axles use 5 bolts on the backside of the hub and 9/16 in U-bolts. They typically have tube diameters of 3 in. Make sure to measure. If you don't upgrade to the shackles Lew sells, make sure even if you have upgraded HD 1/2 in. shackles to measure the length. If it is 2 in they will not work, must be 2 1/4 in. Make sure to measure. Lew was great to deal with as always. @ScubaRx I did confirm that he does not want his 2/12 in U-bolts back. Hopefully, this adds to the conversation since both of these issues came up for me.

They may not both break at the same time as they tend to flatten prior to actually failing. Correct, Last season, We arrived in Inuvik, NWT where we discovered that one of the rears snapped (same area as most previous pics). We were able to replace it (similar, but not exact) and we continued onto Tuktoyaktuk. On the return to Inuvik and the same mechanics shop, I thanked them for their help, but noticed the other 'rear' had snapped (same area as most previous pics) sometime between Inuvik to Tuk & back to Inuvik. Note: I drove to Inuvik on the way up the Dumpster, and Maggie drove from Inuvik onto Tuk and back to Inuvik. While waiting for the 2nd replacement leaf spring, we found that all four shocks were blown, (this may have been before the trip), we just did not check them before we left for the trip and that probably contributed to LS failure. We had 4 new Monroe 555001 brought in and installed. a couple days later the leaf spring arrived and we were on our way to Whitehorse for 4 new/matching leaf springs. In Whitehorse, they installed 'UNA-212' rated Capacity: 1,830 lbs. each, the 4-leaf measurements were close enough for us... Oliver uses the MPN: UNA-210 rated at 1,750 ea. We made it home no issues, and back up to AK and around this season, no issues. Just not the NWT. So we are running with something a bit different than most of you. We will keep an eye on our shocks. I see some pics of something different than the High Gloss Black 555001 Monroe's on other trailers I am not going to make any changes until I see what OTTO’s comments are after this camping season.
