I have D52s rated 3500, the guy at Alcan claimed these were somewhat different than D52s rated 5200 - the brakes when I questioned him. Not sure I believe it.

Not, something miscommunicated! Your D52 axles are labeled 3500 only due to the OEM installation of 1750 LB springs. They are the same D52 axles. With an Alcan upgrade you’ll have a 10K LB suspension, but 3500 axle labels and 7,000 GVWR legally per the DOT sticker on the body.

Awesome, now 37 pages in a dead heat with “Where’s Ollie!” 🤣

He seemed unsure about it when I pushed on the point. I think he was thinking about the difference between a true D35 and D52. It would be very unusual for Dexter to gimp the brakes specially I think as it would complicate inventory. Easier/cheaper to take a stock D52, ship it with the stock 1750’s and just print a new label. 

OK so with this new 2026 axels I’ve got, I’m having them just upgrade the springs, and I’m bringing Bulldogs with me to replace the stock shocks. They mentioned D rings, those will get replaced it sounds like, but the EZ flex and the rest of it will get reused as-is

Wow, all day long and no replies here on our 36-page Alcan thread! 🤣

Robert, you have a newer hull, so I assume you have D52 axles. Those with D35 axles should upgrade at the same time (my build thread below). You want to install everything NEW; D52 axles, Alcan 5-pack leaf springs, a new EZ Flex kit and new shocks.

I had installed new shocks the year before, so after they tested good, I reinstalled them. I wish somebody would come up with a HD replacement shock (I've looked)! The Bulldog shocks are likely better than the OEM Monroe 555001 shocks, but they are both light duty shocks designed for 1750 LB springs. I wonder if the Oliver would tow any different without these shocks, given the HD Alcan springs. I'd like new HD shocks with similar min/max length specs but heavier, larger diameter shaft, piston and casing.

Do differently? I would purchase the full Dexter EZ-Flex kit with HD shackles and wet bolts. I purchased the wet bolts from Alcan and new EZ-Flex center links only. I do love Alcan Springs, but their shackles and wet bolts are not splined so do slip, so not as good as the Dexter wet-bolts that come with the EZ Flex kit. Another route would be to look at a MORryde substitute for the entire EZ Flex kit. That's all I see, more info here =>

 

Thank you for this detailed information 

we are roaming around Colorado and I was thinking about contacting Alcan to check on appointment availability for the upgrade.

Maybe we will just pick up the springs and haul them home to complete the job after we gather all the other parts , shocks, EZ Flex, Shackle U Bolts and wet bolts 

 

Thanks a million

You're welcome, Robert. That's great that you are in Colorado! You should definitely visit Alcan like I did on our trip, purchase parts at a minimum, get the Alcan Leaf Springs and get their U-bolts also to mount the springs.

Your Oliver is a 2022, mine a 2016 needed everything. I'm assuming you have the HD EZ Flex kit installed from new. For example, if you have towed 50K miles in 4 years, your EZ Flex equalizers are likely shot. There is a section in my post about the equalizers. They wear cock-eyed inherent to their design. If your mileage in 4 years is much lower say 20K miles, they may be OK to be reused.

Shocks don't matter much. If you had Alcan work the spring install, you could ask them to test the shocks. If bad they could replace them if available, or just reinstall them as-is and you could DIY new shocks at anytime, a simple task.

Many on this forum and elsewhere are adamant about the wet-bolts installed in a certain 3 or 9 o'clock position. I'm not sure that matters, I worry less about some things. Since the Alcan wet-bolts were not splined, I just mounted ours in random positions. When I grease, I usually get one Zerk per side that will not take grease (yes wheels and load OFF). I just loosen that bolt, give it a 1/4 turn, apply grease and retorque.

To date, only one Oliver owner had issue with the Alcan shackles, where they got buggered with use. The same owner went with an extremely light torque setting, hence the damage. No other complaints from what, 200 Oliver owners with Alcan Springs!

If you believe in the 3-9 positioning get a HD splined set instead. I also thought afterwards, I could have bought the full HD EZ Flex set saving money. If needed when there, purchasing Alcan wet-bolts would be fine. One thing I can tell you is they will reuse everything good and are not the kind of outfit to upsell their customers.

Another thing I would have done differently? If Alcan had in stock the axles I needed, in hindsight, I would have had them do the whole job when I was there. They charged others a very reasonable $600 for labor, and got the job done in a half day. I enjoy DIY on my vehicles, always pay for parts only, dislike paying for contract labor! But to install axles and springs was a long hard job for one old guy at home (my son helped when asked), pacing myself I spent a few days!

They certainly would have fit me in vs. allowing me to drive off that day! They measured our Oliver and spent so much time with me. Our Oliver is one of the few with the 50" axles, while Alcan had a whole pallet of 50.50" axles for their Oliver customers. My axles had to be custom ordered, so having them do the work while we were in CO was not in the cards.

You have a lot to consider. I suggest you keep the installation option open. Call them and talk to Lew or Tim. Let us know how it turns out for you!
