Shocks for Duff long arms
IΓÇÖm having Duffs long arms installed and the shop called to tell me that I need longer shocks as the current ones are limiting maximum droop.
I forgot I would need longer shocks.
I have 4-1/2ΓÇ¥ WH springs up front and went from stock radius arms to the Duff long arms.
1) anybody happen to know how much longer of a shock I would need ?
2) any input about Duffs new MS2020 Eibach shocks ?

Re: Shocks for Duff long arms
IΓÇÖd recommend the ones you can get delivered and installed in the next 10 days...
Seriously though, try the Duff Eibachs and let all of us know how they work.

Re: Shocks for Duff long arms
So the springs arenΓÇÖt limiting the travel but the shocks are? Can the shop measure the length at full droop and then also measure the length at full stuff? You could then find your shocks based on those numbers.

Re: Shocks for Duff long arms
What I would do is bring it home. Jack it up and support by the frame. pull the front springs out of it. articulate the front axle (mostly for full stuff). Get front axle at full stuff. Measure collapsed length of shock needed. Find the longest shock that can fit in that collapsed spot. Since you are not running tall shock towers you will be limited.
As for shocks I'd get something custom to finalize the ride. Go for a ride in Chris' red bronco and see for yourself. But to do that it would be best with a new shock tower and rear shock mounts. Allows you to run a 14in shock up front and a 12 or 10 in the back.

Re: Shocks for Duff long arms
If I get a chance IΓÇÖll take one off of mine and measure. I have 4.5ΓÇ¥ springs on mine with cage arms. Seems to do really well.

thank you Bob
not sure where the shock mounting location on the cage arms are compared to duff.
I have a call in to Michael Duff to see if he happens to know based on experience

Re: Shocks for Duff long arms
Glad the shop owner is helping out. IΓÇÖd think you could take your measurements and get some Bilstein 5100s for under $200/pair and then after SuperCel decide what the long term solution is. Probably sell the Bilsteins for close to what you paid.
Duff might be able to also tell you what works since you have a standard lift and didnΓÇÖt change the shock towers.

Re: Shocks for Duff long arms
Duffs got em packaged up and on the way
I gave him current spring and shock details and he selected the right ones with the "you didn't give the measurements so it's on you" disclaimer so I have my fingers crossed that it works out
If they are right and I like them, may keep the current set up for a bit before diving in further
thanks for the help so far guys

Re: Shocks for Duff long arms
If there not to your liking, Have Duffs bring you another set to swap at SC and have landsharks pit crew change them out Baja style.

Will the landshark team do that there? Trail repairs too? Better plan my runs with them

Isn't 27 years classic?

So sorry. The non-compete clause of our contracts don't allow us to work on other Broncos.
