Hydro bump stops (1 Viewer)

Also, I'm still looking into the front bumpstops since moving to 37's. The taller frame mounted rear bumpstop that is part of the Slinky kit should be the correct size (1" taller) than the stock frame mounted front bumpstop. That' probably what I'll end up doing in the front since I'm not sure if there is room for Timbrens up front. I should be getting some of the taller "slinky" bumpstops this week and can compare and check clearances.

@Box Rocket - did you order from Timbren direct, or from Nitro Gear? Nitro has the "special" bump that is Toyota/80 specific, unsure what you would get ordering direct from Timbren.

Visually, those look the same as mine....roughly 4-3/4" tall, 3" diameter, double bellows

Mine came directly from Timbren. I didn’t just order from the site but was emailing back and forth with one of heir guys. He said they’d find me the “right” thing for the 80.

The visual difference I am seeing between what I got and the photos I’ve seen from you guys is that the beveled part of the bumpstop is probably twice as tall as the ones on mine. Mine seem more compact overall.

The ones you pictured look like what I’m using up front. If I have time today I’ll try to post some pictures. Currently I’ve got over a foot of heavy new snow and it’s supposed to continue through Friday. I’ve got a date with the snowblower after a cup of joe.

Otherwise I responded to your PM already.

From what I've been able to find the taller ones are what are included in the Timbren SES kits (Suspension Enhancement System) and are designed to work more like a helper spring and be in constant contact with the axle housing to provide extra support. The shorter ones are for the Active Offroad Bumpstop kits. Whether or not there is really that much difference between the two I have no idea.

All "real" hydraulic bumps will compress easily on slow speed stuff and will not effect articulation. With no nitrogen pressure you can kinda feel how the valving works by hand, just push down on them and you can feel the oil pushing around the shim stack. I have ran many brands and types of bumps over the years, including timbren, lightracing, and traditional hydraulic bumps from king, fox, and radflo. Timbrens are just rubber springs, and by increasing the spring rate on hard hits causes a lot of bouncing. They are great for street/pulling a heavy trailer, not great offroad. The lightracing jounce shocks were amazing while they worked, however they are nearly impossible to rebuild at home and only lasted me about a year before puking oil out. I sent them off for a rebuild and sold them for Radflo's. Those have been on my taco for almost five years, probably 30K dirt miles. No leaks or issues at all. Once a year, I pull them off, clean them, have a look at the oil, reassemble, charge to 130psi and forget about them for another year. The wear pad on the contact foot needs replaced, other than that they work as well as the day they were installed. I wonder if the 4runner kit from Icon would work for us?

I have the LX570 and I was wondering if anyone has developed these for that rig? We have the rubber factory cone and the small rectangle rubber block for when the axle hits (to the left in the pic but smaller). It has very soft springs and I end up on the rubber bumps a lot. I'd love to have a smoother bottom out with the factory suspension.

I'm considering hydraulic bump stops. Wondering if any of y'all have had good luck with a particular product. I see readily available aftermarket from icon and King, what's been working for you?

I hear the ride quality with hydraulic bump stops is amazing.

Hydraulic bumps are only going to affect the ride when you bottom out the suspension. They will soften the harshness of bottoming out. If you're driving style has you bottoming out your truck in pretty rough ways then the Hydro bumps would be a nice upgrade. If your driving style has you occasionally bottoming out the truck but they aren't really harsh hits like coming back to the ground after getting 5' of air then you could also do something like Timbren bumpstops. I've had Timbrens for the past few years and they've done a great job smoothing out those hits when the suspension just runs out of compression. I have been known to get the truck in the air from time to time (not 5' of air LOL) and the timbrens have handled that pretty well too.

The earlier comment about Timbrens just being rubber springs and increasing spring rates is not exactly correct for 80 series applications. For leaf sprung trucks like Tacomas the Timbrens are more like a helper spring that acts as a bumpstop when it cant compress any more. On an 80 they aren't in contact with the axle until you're nearing full compression (like a real bumpstop or hyrdro bump). So they won't cause the "bouncing" etc that were described in an earlier post. Timbren has products called SES (suspension enhancement system) which is like the helper spring. This is what is often used on trucks like Tacomas. What you want is their AO (Active offroad) bumpstops. Those are the progressive bumpstops that increase stiffness as they compress, similar to what a hydro bump does. There's no way to tune Timbrens like you can a hydro bump (or air bump) but they are a nice upgrade on an 80 IMO.
