Bump Stop Recommendations

Any recommendations for bump stops for my 2017? Just changed out my Bilstein 5100’s for Kings 2.5 coil overs with stage 3 Deavers. Anyone?

Exceptionally satisfied with my Durobumps, full air and bottom out, didn't even know it.

+1 for Durobumps

Sumo Springs here, front and rear. Research them, they are nice but expensive.

 

These are on my list. Green springs, blue bump stops. Gonna add some red tow hooks and call it good

 

I did the blue, riding on some 5100s and a rear block. They soak up some serious bumps, rides even better than ever.

 

Sumo was recommended by a buddy as well. Seems to be the favorite of a few guys I’ve talked to. Thanks for the quick replies everyone. Keep sending em.

 

i have Timbrens with the flip kit and they function very nicely. if i was to do it again i would get the Archive stuff since i have quite a bit of his stuff on my truck and it's top quality.

FYI, unless they are talking about a different product from the regular Sumosprings, then they are not actual bump stops but rather like helper springs to support weight and protect bottoming. that's these: SuperSprings SSR-612-40 | SumoSprings Rear for Toyota Tacoma, blue

$280 SuperSprings SSR-612-40 | SumoSprings Rear for Toyota Tacoma, blue

if there's any actual bump stop option from them then disregard.

i had Sumos on my truck for some time and used them kinda like a bump stop with no significant weight in the bed. that made my truck buck like crazy on the highway. after pulling those off and getting the Timbrens on, my rear shocks actually started working, and the Sumos were trashed, lost about 30% right off the top of them. the Sumos kept my rear suspension from compressing when the bed only had a spare and 40lb of sand.

 

oof. How much of a lift?

 

5/8" only in the rear.

 

This, option 3

 

Same 612-40s working well for me. I’ve been riding literally on them for a long time (installed after cap sag). They’ll be my bump stops once by Deaver expos are installed in a month or so.

 

Locked offroad

 

Sumo's front and rear. I'd buy them again without hesitation.

 

They are awesome, read up on how they are made, pretty impressive.

 

They break-in pretty well. Since I have been riding on them since I installed them, initially they felt bouncy when I’d hit bumps, but they either lost some of that rebound feeling or I got used to it. They seem to work with my suspension now, but looking forward to installing my Deavers and probably having a much better ride overall.

 

I wanted some of the fancy bump stops but I have a hard time spending $250 on bump stops, especially when my type of off roading is slower more technical stuff.

I ended up going with GM bump stops (PN 15712438) and they have been great for me. I just don't feel the need to spend an extra $200 on bump stops for my truck when I'm not trying to through high speed sections. They are a progressive load bump stop similar to the others out there and were made for 1/2t and 3/4t pickups, so our little yota's won't bother them. I know it sound like I'm talking trash about the other bump stops but I don't mean to come off that way. Some things just aren't worth overcomplicating or over spending.

Best picture I have on my truck. I have 6112's, B110's rear and OME med leafs FWIW.



Here is a thread going over it a little more as well.

I think I am going to follow your footsteps here.

 

Let us know what you think of the GM bump stops and how it goes for ya. Sorry, this reply got more wordy than I was expecting... I'm not good at explaining things short and simple. lol

Just incase you missed it in the research. The washers/spacer length for the bump stop mounting is going to be based on the collapsed stroke of your shocks that you end up buying. My setup with the B110's (16.34" to 27.28") I needed a little more of a spacer than a standard 5100/5160 (13.84" to 22.4"/14.22" to 24.06") as they are pretty much the same stock, if I recall the OEM TRD OR Bilsteins are 13.98" to 22.94" for 2nd gens. Oddly enough the 5100's for 2" lifts are roughly the same or even slightly shorter, so your droop won't change and if lift it 2" you'll be that much closer to the extended travel at all times instead of the piston resting closer towards the center position. Many other "2 inch" lift shocks are similar to the 5100/5160 length, FYI. There are also 5165 non reservoir and 7100 with reservoir options that come in many different lengths/travel and valving options if you want to go with Bilstein.

How to measure the amount of spacer you need. The GM bump stop is apx 4" in length with about 3" of usable compression, see link below.

- With everything installed and wheels off both sides jack up one side of the axle as far as you can to try to collapse the shock fully. If it doesn't reach fully collapsed, take your measurement and subtract the difference from the manufactures collapsed length. IE (B110 ref) 17.5" measured, known 16.4", you'll have a 1.1" difference to add to the next measurement. Measured from the center of the eyelet hole or bolt and the bottom of the washer closest to the body of the shock. See below.

- While it is still in that position. Measure the distance between the upper mount (where the bump stop mounts) and the top of the leaf spring or plate if doing a U-bolt flip. Then add the .9" difference to get the total length needed.
- So lets assume some measurements. Again, using the B110 reference above..this is just for numbers, not actual measurements made by anyone. Ref pic below.
Actual top of leaf spring/U-bolt flip to mount - 4.5" (BSC to bottom of mount/top of BSH)
Collapsed length of shock as far as you are able to - 17.5" (IL)
Fully collapsed length (per manufacture) - 16.4" (rounded up since tenths of an inch will make this hard to measure in reality)
Usable compression of bump stop - 3"
-THE MATH-
Compression and fully collapsed difference - 17.5"-16.4"= 1.1"
BSC to frame - 4.5"-1.1"= 3.4"
Since the known usable compression of the bump stop is 3", the amount of spacer required would be .4" or 3/8"-1/2" would likely be fine because there is always a little wiggle room since it is squishy. Make it slightly longer if you want to err on the side of caution.



I am not a suspension expert, nor do I doubt your abilities/level of education (this is to help anyone looking, hopefully) but this is just basic math that is comparable to making up any distance in carpentry or other home projects. We're not designing suspension dynamics for professional level performance in a dedicated driving situation, OEM and suspension manufactures already did that homework for us. All we are doing in this specific situation is stopping the shock from bottoming out to prevent damage and increase the shock's longevity. Besides, you likely aren't slamming your truck through high speed baja sections otherwise you wouldn't be asking these questions and a shop would likely be doing $10k+ of suspension and chassis work. The GM bump stops are more than enough for the majority of Tacoma owners (except they give you Instagram points, lol just playing) that do "normal" slower paced trails, realistic camping trips (not the over the top overlanders) and normal truck stuff like towing or loading the bed reasonably. Most Tacoma owners don't overly abuse their trucks since most drive to the trails, camp, have to drive back home sometimes 8+ hours and its their daily driven vehicle. The GM bump stops work for idiodic drivers heavily abused 1/2t and 3/4t chevy's, so they are more than adequate for what our trucks can handle by comparison. Sumo and Super Bumps are made from microcellular polyurethane elastomer, just like the Gm ones. But they differ in density, we'll never know by how much likely.

Now I'm not knocking the other bump stop products. They are great! But reasonably speaking, most of us will never use the capability of Sumo Spring, Super Bumps, etc. I'm a gluten for overbuilding everything, but I have to reel myself in sometimes. Saving $200 on something simple like bump stops is huge!! You could throw on a set of DD SS3 Fog lights for that, a new AGM battery, a better jack, other maintenance items, ect. Remember the age old KISS concept: Keep It Simple, Stupid
