After speaking with engineers at Timbren and Sumo, I went with Sumo. I added Icon rear leaf springs in stage 2. Used the Sumo mount and spacer. I did not add the FO Spacer. The Sumo are quite a bit larger diameter than the Timbren and have a more progressive impact resistance with a softer start point and the impact area is spread with far more surface area. As directed from Sumo, I allow them to impact the axle. Mind you, there’s quite a bit of space between the Sumo and the impact point, so they really serve more as a real Bump Stop and the Icon springs can be used as designed. I’d need to add another spacer or two to use them as you do. I have Geiser springs up front. I think they’re a softer ride than the Eibach’s at the start, but they’re definitely progressive in that regard. They get stiffer quickly. Where I live, I tend to do more trail riding. No open desert in Tennessee. Icon makes a spacer as well, probably similar (but definitely not identical) to the one you installed.
A quick follow up. Over the last weekend, given some recommendations, I’ve added (took 20 minutes), an SDHQ BumpStop Pad to the truck. That reduced by 1 3/8” the gap between the bottom of the Sumo Spring and the impact area on the axle. Was it necessary? I don’t know. While doing street driving, I wouldn’t notice given the still pretty large gap. I didn’t measure, but I’m going to guess that the gap between the Sumo bump stop and the impact area on the Sumo is probably 3-4”, maybe a bit more.I can measure if anyone would like that info. Bottom line, the new spring can move and act as designed, and the bump stop will impact early enough to protect the truck offroad.
@@sethrad8626 did you have any issues running the sumos with out the bump stop pad?
@@Ellacost831 The stock bump stop pad is ridiculous.
I'm doing the Deaver +3 and looking for a sumo setup that will work as a bump stop only. Don't need for towing. What sumo setup did you get? When you're talking about spacers, are you referring to the standard mount from sumo? And I'm assuming FO spacer is frame only?
@@629jhughes I went with the Raptor specific Sumo and used two of the Sumo provided plastic spacers between the frame and the Sumo)…and eventually added a SVR bump stop pad on the axle (takes up more of the gap between the axle and the Sumo, and offers a wider pad for contact with the Sumo). I have to admit…the setup works great! Key is to figure out how much space you want between the axle and the Sumo. Sumo engineers told me their thoughts…and Icon had their thoughts. The greater that space, the more work your springs do before the Sumo kicks in. If you just want to use the Sumo as a replacement bump stop pad, consider using one spacer. A lot might depend upon how aggressive you’re riding. Where I live, there is no high speed offroad like in the desert. It’s not hard to add a second spacer. Try one, see how you like it, then consider the second. The SVR bump stop pad seemed like a great idea to make impact with the Sumo…but that’s just my thinking on the issue.
Thanks for the video. I have Deaver +2HDs on order and am actually looking at bump stop and strike plate options right now.
I have the Timbren SES which are slightly different than your Active Off-Road kit but they both seem to mount offset. I didn't realize that so thanks for pointing that out.
Did you notice you had more space between your bump stops and bump stop pad with your lift?
I’m maintaining stock height and am trying to decide between the flat or raised bump stop strike plates.
Off-Road Alliance carries them both.
TIA
Great vid. I carrry some weight on mine too and am upgrading to ICON's on stage 2. I contemplated the Timbrens for the similar reasons as you, but decided to go to SVC hydraulic and Fox 2.0 IFP's. Agree completely about Offroad Alliance. I've also had great service from a couple of the other vendors who also support the Rap community and don't do business with those who don't.
I am going to do drop shackles with the Icon's on stage 2 to decrease the rake. I am 200lbs on the daily and maybe 450 on trips. Did you do stage 2 and stock shackles?
I am currently sitting with the Icon Option 3 and stock shackles, so with the standard set and the add-a-leaf. The springs showed up with option 1 and I swapped to option 2 (swapping a leaf) and did the eibach springs up front at the same time, but ended up with negative rake any time I carried a small amount of weight. I then had to source some new pins to swap everything again to option 3. If you lift the front at all then don't do drop shackles. If you decide you want to change it down the road you can get new pins here: www.summitracing.com/parts/TFY-92012
@@ruffwrenchn2235 great info. I'm 200 lbs EDC and maybe 450 on trips. I've seen some guys that regretted going stage 3 with that little weight. I might do FRS 3's live valve all around and would maybe add an inch in the front...don't want too much. I guess I can swap the drop shackles in or out as needed without too much work. I bought spare pins already...just in case I go with stage 3 at some point.
How are you liking this setup? I have 2017 raptor with eibach up front and am installing the icon rear springs this week, option 1. I bought the timbren off-road pads also, then came across your video.
Great video man. Do you think you might be limiting your travel by having both the RPG and forged Offroad spacer? Seems to me like you’d only need one or the other.
This can be confusing. The Timbren bump stops are made to be used with the stock block/bump stop pad. They come with the "active" bump stop and a mounting bracket. The bracket height was nearly that of the RPG spacers so there was minimal difference when I added the RPG spacers and removed the bracket. The Forged off-road bump stop pad replaced the stock block so everything should be in place the way it is supposed to be. The reason it seems odd is because the "active" bump stop is meant to be significantly compressed when used to reduce that shock and momentum over time/travel. That is why they are ridiculously long; they act kind of like a hydraulic bump stop by absorbing the impact using rubber instead of compressed gas/oil.
Do you have the Geiser or Eibachs on the truck? All the shops say that geiser are way to harsh. What are your thoughts? I did see your note in the description can you go into more detail or maybe make a video on that topic? Thank you
I have Eibach on the truck. The Geisers are usually a better route since they are progressive and not linear like the Eibachs. I usually hear people say that the Eibachs are harsh and primarily for on road driving. The reason I went with Eibachs was cost, my comfort with the brand, and the fact that they have a smaller lift than the Geisers. Since springs produce a lift using preload, the Geisers might inherently be harsher (Since they "lift" more), but their progressive spring rate is desirable.
hi. thanks for great detailed video .
may i ask what was the stuck payload and how much you did increase the payload capacity by upgrading spring and spacer ?
Option 2 is about 20% more payload.
Is that contact pad something you put on with the upgraded leaf springs? Or is that the stock contact pad?
Forged off road bump stop pads. Link in the description. Unfortunately the stock 2” lift block has the impact pad built in. When you install the new leaf springs you have to remove the block and then replace it with something else unless you do a long spacer and have the bumpstop impact the axle.
How’s the timbrens holding up at high speed ?
Looking to do the same for my raptor
I haven't had any issues, but can't say that I'm taking anything hard either.
