Alright boys I'm too broke for air bumps and have been running 3" of hockey pucks in front springs along with my acos spring adjusters with the stop on it. I'm at 3.5" lift with 31" tires. I'm pretty sure our front spring I'd is 4 inches and I've been eyeing a cheap alternative to the hockey pucks that's a Lil softer of a hit if and when I whack them. I noticed the Tacoma has some cheap options that are 3" diameter and about 3-4" tall that are listed as polyurethane "air springs" look similar to sumo springs if your familiar. Even have bolt on bottom so I can bolt to spring perch. Anyone ran something similar? For 40 bucks I'm gonna try um out.

Those hockey pucks are notoriously harsh — a lot of guys hate the stiff hit on a 3.5" lifted XJ.The Tacoma poly “air springs” / Sumo-style bumps you’re looking at for ~$40 are a solid cheap try. They’re softer and more progressive than solid pucks. Just make sure they fit your ~4" spring ID and bolt up cleanly to the perch.

 

That's a good idea. They look exactly like sumo springs. In fact they have the same part number as sumo springs.

I have sumo springs on my motorhome. I found that if the sumo is too tall it can be easily cut to length with a saw or bread knife.

I just installed 2" of hockey pucks in my '98 XJ. They seem to be adequate .

 

I'm in the process of trying new front springs, and I have a set of bump stops similar to those arriving today. The ones you bought appear to be SumoSpring knockoffs. I thought I read some reviews indicating the knockoffs didn't work well, so let us know what you find.

I bought Energy Suspension brand which have a hole in the middle, allowing them to be through-bolted to the bumpstop mounting point like hockey pucks:


The product description indicates they are made from a compressible material, probably polyurethane sponge.
