DIY Bump Stops

Bump stops are way overpriced. $300+ for four chunks of rubber? Not for me!

After some searching, it appears Jeep people have been known to use hockey pucks, which are much more reasonably priced pieces of rubber.

Anybody have any thoughts on good sources for 2-4" tall chunks of rubber? I'm quite certain there are better options that will require minimal modification and save hundreds of dollars. Even willing to raid a you-pull-it to source these.

 

Friday comes fast these days.



I think you are misinformed, old school jeepers used hockey pucks for body lift, they would make horrible bump stops.

The reason bump stops are expensive is the R&D to get the durometer just perfect for the application and to provide progressive dampening, a hockey puck provides no progressiveness.

Buy once cry once there's a reason people pay $300 for them.

That said check out wheeler's super bumps they're not that expensive (I assume you saw the Timbren kit and baulked.) Or the DuroBumps both good products purpose build and engineered vs something that won't work properly or will be potentially dangerous like a hockey puck or some repurposed stock part from another vehicle that would be even worse than factory.

 

Hockey pucks are made of vulcanized rubber. They will break before they compress. Bad idea for a bump stop.

 

Energy suspension or other companies make various universal bump stops that can be made to work at around $25 a pair.

Edit: maybe a little bit more $ than what I said. Prices have went up in the last couple years. Also, full disclosure: I have superbumps front and rear.

 

Prothane is another company. I had their body mounts and Energy bump stops on my old Suburban.

 

Right, I was thinking that vulcanized rubber like a hockey puck would be too hard so I'm looking at any and all rubber chunks for random applications.

For example, these bumpers are extremely cheap and are in the neighborhood of dimensions needed, while still providing some flexibility:

Hmmm

It looks like Prothane and Energy Suspension have exactly the price range I'm looking for, for essentially the same form factor as the overpriced Duro/Wheelers/Timbren parts. As long as I roughly match the shape and size, I can't imagine the performance difference would matter enough to justify the extra $250-300 price tag.

As posted above, McMaster has plenty of good options too.

 

Plenty of cheap ones out there if you're willing to make them fit

Not technically a bump stop (or rubber)but could be used as such:

Coil Design Helper Spring

Had a pair of these on an old sagging dodge in the early 90s. Mounting hardware was junk but once that was sorted they worked fine. Too tall? use a grinder and cut to fit.

 

These are drop in replacements for the front bump stops on the 2nd gen Tacoma, along with a M10x1.25x40mm bolt. $25 for the pair:

Working on a solution for the rears now.

 

Alright I figured out a solution - for the rears, using these:

Rear Jounce Bumper 15712438 523-049 Compatible with Select Chevrolet/GMC Models, Rear Axle Rubber Bumpers (2pack)

https://www.amazon.com/15712438-523-049-Compatible-Chevrolet-Bumpers/dp/B08MQGR3V3?ie=UTF8

I will use the Wheelers U-bolt Flip Kit, and then fabricate an adaptor bracket to mount from the Wheelers plate to the bump stops. I have a full machine shop at work, so the brackets will basically be free and cost no time.

So I'm at about $60 for the bump stops and hardware, saving me about $230 compared to the cheapest commercially available kit.

 

Who's paying $230+ for non air bumps?

 

Not me! Got a link for anything cheaper? Looks like Wheelers, Timbren, and Durobump are all in the >$200-300 range for just the front and rear bumps.
