When the rear end drops under a heavy load, handling and steering can quickly feel off. The Timbren Rear Suspension Enhancement System adds up to 2,400 lbs of support above the rear axle to keep your vehicle level and steady when towing or hauling gear. The hollow rubber springs replace the factory bump stops and automatically add resistance as weight increases, keeping your ride height even and maintaining proper traction and braking.
Rough pavement and uneven terrain can make a loaded ride harsh. Timbren’s Aeon hollow rubber springs compress progressively to absorb road shock and cushion bumps so the truck feels more controlled over potholes, washboards, or jobsite ruts. With no air lines or compressors needed, these rubber helpers work quietly in the background to smooth out the drive while extending the life of your vehicle’s suspension.
When a trailer starts to sway or a curve pushes your vehicle sideways, each Timbren spring acts on its own to support that side. This independent action cuts down body roll, reduces bounce when turning, and helps off-center loads stay balanced. The result is better stability through mountain passes or when a passing semi sends a gust your way.
Adding load support doesn’t need to be complicated. The Timbren system bolts directly onto the frame rails above the axle using included brackets and hardware—no drilling required. Once installed, there’s nothing to adjust or maintain, just reliable performance every time you hook up a trailer or load the bed.

The bump stops are working great no issues installation was easy. Keeps suspension from bottoming out with heavier loads.

Thanks for taking the time to share such a detailed review and all of the pictures! The unloaded ride is a concern we hear fairly often with SES upgrades, so your experience with the 1" gap and rough-road testing will be really helpful to others considering these for their F-250. We appreciate the kind words about Naomi and our team as well. Looking forward to your update once you get some miles on them with the Rockwood!

Love hearing this! Really appreciate the detailed feedback and photos. That extra stability when you're loaded up can make a huge difference. And installing them at 11 at night—that's commitment. Hope they treat you just as well on those mountain roads. Safe travels and we'll definitely make sure Dee Dee gets the shoutout.

Wow, thank you for sticking with us, Don! That is awesome. I think you made an excellent choice here. Timbrens are tough and the heavy duty are SUPER tough. Glad to hear these were a good fit. Love the photos! Is that your own property?

The TIMBRENs work as stated during when I am pulling anything heavy. However, when the truck is not pulling anything, anyone riding in the rear seat gets a very hard jarring jolt when driving over any roadway repairs, bumps, expansion joints on bridges. I wished that I would have went with the Super Springs, or the Road Active Suspension. I may replace the TIMBRENS later.

That is great to hear! I am glad they made your drive in much smoother. Where do you hunt? I'm guessing way back in the woods if you need a UTV as well.
