Has Anyone Had the Timbren Bump Stops Fixed on Their 4th Gen Toyota Tacoma?: Heard it enhances towing performance

Hey, guys! Been in Rubicon prep mode for the past few weeks... One upgrade that was high on the list was a front locker. I have an Off-Road, so the rear came with the factory locker. For more technical trail rides, I wanted to add something in the front. I looked into a few options, but the Eaton was available the fastest and didn't require additional mods (like an air locker, for example). We dropped the diff in the driveway (definitely harder to do on the ground) and took it to Bent Motorsports to have them install the actual e-locker inside. They got it done quick and we got the diff back home and reinstalled everything. Currently figuring out how to best run the leads and connect power to the locker. I'm thinking we go straight to my switch panel, but we'll see how that goes. Quick FYI... to the best of my knowledge, the new gen Toyotas all use the same 8.0 IFS front diff seen on previous generations. This is great news, because they didn't have to develop an entirely new setup. So if you're looking for lockers... check out Eaton. https://www.eaton.com/us/en-us/catalog/differentials/eaton-elocker-differential.html

Someone told me about Timbren bump stops and how they'd be a valuable upgrade for my truck. What caught my attention was when he explained how it would significantly improve my truck's towing performance.

After hearing what he had to say, I did my own little research and found out that it helps to reduce rear sag, sway, and roll. There's also Timbren's Suspension Enhancement System (SES), which uses Aeon rubber springs to absorb heavy loads; that would help to ensure a more stable and level ride.

Compared to factory bump stops, I think Timbren’s progressive spring rate aids in minimizing bottoming out, which offers more comfort and control during towing.

Can't really say about the installation process, but from what I've read so far, it's quite easy to install, and more interestingly, it requires no maintenance.

Given they're ideal for heavy loads, it means reduced suspension stress and driver fatigue, making towing safer and smoother for owners who carry out lots of towing activities. I'd do well to check it out and potentially have it installed on my truck too.
