How Coilovers Work 101

So someone tried to jump speed bumps with a 3" spacer lift?

 

Your explanation of the Bilstein makes sense to me. However, why do many people say you need to run bump stop extensions with them?

 

Bump stop extensions make it so you dont be come one of the people in the picture's @T-Rex266 posted. You want to contact the bump stop before the shock bottoms out to prevent damage to the shock (hint: your shock shaft should not be an L shape)

 

Great post, but for the rookie like myself it means jack shit. Are you telling me if I want to level my truck just get the Bilstein 6112's at 1.9" and be done or what?

 

He said you don't need them with Bilstein's. Only with shims/spacers

 

Basically if you want to use CB shims, get bumpstop extensions which CB sells too or buy SuperBumps, both increase where the height of the stock bumpstop would be, and keep it on the street.

 

So I have installed the 5100s with 1/2 shim on top and 5100s on rear also with 1 inch lift so should i replace the front bump stops

 

Good stuff man ... Do you do online courses? lol .I love learning this stuff! Thanks for sharing.

 

I know first hand..... on a 7in bds lift New Kings are on their way!

 

On the front, there are 4 rock hard stock bumpstops, I replaced the ones behind the axle with SuperBumps and when I smack them, it's a whole lot less jolting. I imagine if you didn't add extensions, there's more space before you hit them and probably not good for the shock if you fly into an unexpected deep pothole.

In action on a Taco:

 

Thanks. My plan was to use 6112's on the front and go on with life. I'm 99% street driving anyway.

 

I can't wait to get rid of my stupid spacer lift! Elka needs to speed it up with their Tundra stuff

 

It could be Bold, Underlined, and in Italics and people would still miss it. At least that's the way it seems

 

I've heard about them for a while. I looked under a few of @TOTAL CHAOS rides and started asking a million questions. They are currently testing on a Tundra and GX470.

Elka is going to give King and Fox a run for their money... especially in cold weather climates

 

IDK, im a bit skeptical. Are two quarter inch spacers really going to lead to this type of damage off road? Maybe at very high speeds, but even yes, i still doubt it.

But hey.. im wrong a lot, so if i am , let me know

 

Thanks for sharing that video. One thing I noticed with the Superbumps is how much they compressed. In a few instances, it almost appeared as if they flattened out. I can see how that may soften the ride a bit by preventing a hard jarring when smacking into stock bumpstops with a presumably harder compound. But I’m wondering if they may compress too much to the point where they may not prevent the shock bottoming out? I remember reading old posts from several years ago on an FJ forum that surmised how the softer bumpstops flattened out so much they failed to prevent damage resulting from bottoming out. I haven’t found anything else on that, though, much less concerning Tundras, so maybe it’s not a concern.

The Bilstein 6112s I got came with some wide washers, which I assume are intended to be added to the stock bumpstops. The original post is an excellent reminder to be sure I don’t forget to install them when I get around to bolt on the 6112s.

 

I’m thinking the same, it be a dampening effect if any. I think the moral is risk of shock breakage if using a top-plate spacer off-roading. Definite street improvement using those, I totally recommend Superbumps like a RSB.

 

Sorry for the dumb question, but what is “RSB?”

 

I hate reading

 

No worries, rear sway bar.

Articulators will take those off but easily the biggest noticeable improvement in street handling.

 

Elka is some quality stuff. Although it is Canadian so you should probably avoid buying it, got to keep America great and all.

 

Thanks for the insight re coilovers, knowledge is always good when it is accurate. My last set of warranty replacement Bilstein 5100's came with new bump stops which I installed. However, it seems like I have to warranty these shocks every 1-2 years due to seal leakage. I have it set on the 2nd notch from the bottom so it is not like I am over extending them and I wonder if Bilstein sent me the bumpstops because of the frequent warranty replacements? 1.5 years now and no leakage and I use my truck off road regularly, maybe the bumpstops fixed it???

 

The spacers are better than no spacers, if your shocks bottom out before hitting the stock bumpstops.

 

Hey now! I bought Superbumps and was charged an atrocious shipping fee, which I was assured in writing it covered customs only to be charged another $43 at the border. I basically paid more than double to support a US company. And you still see me promoting them.
