Thoughts on Rear Suspension Rubber Helper Spring Kit

I have recently noticed these chinese knockoff sumo and timbren rear bump stops on eBay and Amazon.
Thoughts? Has anyone already tried these?

 

Those are aftermarket bump stops. OEM is fine for stock but may help if lifted.

 

Order some up and find out.

My experience with knockoffs is you get what you pay for. In order to meet the low price point, corners have been cut somewhere. Timbrens, Sumo’s, etc, are engineered with a very specific compound, density, and structure to behave as they do; I doubt the same engineering has gone in to these. But that’s just my opinion.

 

I would opt for the Hilux bump stops. p/n 48306-35110 Leaf Spring Bumper stop advice | Toyota Tundra Forum

 

They're helper springs, which are admittedly glorified, oversize bumpstops in the end, but...those are helper springs.

I agree, you get what you pay for. I went with Sumo Springs. They're great, but depending on the weight you plan to carry, may or may not be enough. They were more than enough for the tongue weight of my trailer plus topper plus gear in the back, but nowhere near enough for my slide-in camper.

 

Years ago when i was at a wrecking yard, i saw a full sized truck with a pair of Timbrens under it. I promptly removed them and paid $5 each for them. When i closely looked them over, i was absolutely befuddled on how they could cost so much money. I ended installing them in my trailer. I think both the shape of bumpstop and the rubber durometer could very easily be copied by an overseas company that specializes in copying other people’s overpriced designs. For $60 i would say take a chance.
