When the rear sags under heavy weight, you lose stability and steering control. The Timbren Suspension Enhancement System adds up to 3,000 lbs of load-leveling capacity on the rear axle to keep your vehicle level and steady when hauling or towing. The hollow rubber springs get more rigid as weight increases, balancing the load across the axles so your handling, braking, and visibility stay consistent even when the bed or trailer is packed.
Bumpy roads and uneven terrain can beat up your factory suspension. These Aeon hollow rubber springs act like extra shock absorbers, taking the brunt of bumps and rough surfaces. They reduce body bounce and bottoming out while helping extend the life of your suspension components. The result is a smoother, more stable ride whether you’re hauling gear or towing down rough highways.
When a semi blasts by or a curve pushes you off balance, each Timbren spring works independently to keep its side planted. This design helps reduce body roll and sway when cornering or carrying an off-center load. That means less rocking through turns and better control if wind or uneven pavement tries to throw the truck around.
No air lines, compressors, or manual adjustments required—just bolt the custom-fit brackets directly onto the frame above the rear axle. The included springs and hardware make setup straightforward with no drilling needed. Once installed, the system automatically engages when weight is added and stays out of the way when unloaded for a smooth everyday ride.
The thick rubber construction resists wear far better than typical factory bump stops. To keep them in top shape for years, just rinse them clean once or twice a year to wash away dirt and road salt. Their durable build means you can count on consistent support trip after trip without worrying about deterioration or leaks.

Hello, neighbors and friends, Steven here with etrailer.com. Today we're looking together at this Timbren suspension enhancement system for your rear axle. Now folks, this specifically is gonna work with the 2022 through 2024 Nissan Frontier. That being said, make sure you check the vehicle fit guide here at etrailer.com's website. Top center of the homepage, enter your year, make and model. Make sure you're getting the right parts for your vehicle.
Keep in mind, sometimes videos change and this may fit different years. Now, these will improve your suspension, the overall handling and safety of your vehicle, and they become more rigid as more weight is added to help with the performance when you're hauling those heavy loads. They are gonna increase stability, reduce vehicle sag. They can work independently of each other, so meaning this side here can be compressed down halfway while this side's still up, and maybe it's like an off center load, maybe a camper in the back of the truck, salt spreader, anything like that. Maybe they do also help reduce body roll when you're swerving or turning corners tight, that kind of thing.
They also act as a nice shock absorber, so whenever you're going over bumps, rough roads, those kind of things, potholes, and in turn, they're gonna actually extend the life of your vehicle suspension by taking the brunt of those bumps and rough roads and stuff. Now you're gonna get two bolts here. Those will come from the bottom up and these two plates here, I've got 'em loosely fitting, and you get the two Aeon Hollow Rubber springs. These are a nice heavy duty Aeon rubber, and they're very nice. There is a washer inside of each one of these.
Again, this would go like this. The bolt will come up through the bottom and these plates would go on top, and that bolt is gonna bolt directly into the frame. There's no drilling whatsoever required. It's a very, very truly simple installation. Folks, these do have a nice lifetime warranty.
It's very impressive. You should never have to buy another set again, and they have a capacity rate of 3000 pounds total. So keep in mind, that's just a enhancement. So meaning you're not gonna add 3000 pounds towing capacity to your vehicle. That's just not how it works. These just help assist with up to 3000 pounds of that weight that you're already towing. Well folks, thanks so much for joining while we look at this Timbren Suspension enhancement system for your rear axle on your Nissan Frontier. I'm Steven. Have a great day.

Perfect
Awesome service and fast delivery
Great customer service. The only issue I had was due to my own ignorance. Lift from the frame to relieve any tension on the axels so you can get them correctly. I was able to speak directly to Joshua and the team in Canada, both professional and courteous.
Fast service. Mailed to me the same day I made the order.
Have has Timbren on multiple trucks in the past. It is a must for me. Limits sag when my truck is loaded.
Works great.
It was a perfect fit ! I took the OEM ones off and screwed these on ! Probably 15-20 minutes !
Delivered without all needed parts.
Delivery of missing part was troublesome.
Question, was this a return? Very dirty and some rust all ready on the washers. They look like they will work OK. I know that they will get a lot of road dirt being they will be under the truck and over the springs. I wondered because they came in an etrailer carton and not in a manufacturer's carton.
Well we have the good and the bad, as usual.The good is the wiggle and pressure sway from trucks,busses and other RV's.The bad is as expected,a real loss of the softer suspension that really didn't change without the travel trailer.Although reduced, the wiggle ?sway is still there to a point and now I question the Michelin tires.I have always wanted to try Michelin tires and was one reason for buying the Frontier, but I fear 35psi tires are just a little to soft for the job.So I have to decide whether to keep these tires or move to higher pressure tires for the time we haul the RV.If anyone has any alternate solution please feel free to speak up...
Easy install rides great with truck camper installed
Very quick and easy install. Ride unloaded still
Very pleasant. Haven’t towed my boat yet with this weather we are having. Hope it handles the squat better. Great product!
Finally got them installed and hooked up the trailer. The ride has improved with a load and my daily hasn’t changed a bit. Would recommend it and would buy it again.
A Must-Have Upgrade for Any Load-Hauling Frontier
Item: Timbren SES (Suspension Enhancement System) - Rear Kit Vehicle:2022 Nissan Frontier PRO-4X
I installed the Timbren SES kit on the rear of my 2022 Frontier PRO-4X, and it has completely transformed the truck when carrying a load. I can't recommend this product enough.
Before the Timbrens, my truck would sag noticeably anytime I loaded up with camping gear, a full bed of construction materials, or hooked up my trailer. It gave that uncomfortable, "squatting" look and made the steering feel loose and vague.
The two biggest benefits I've experienced are:
1. Eliminated Sag: The Timbrens completely prevent the rear from squatting under heavy loads. The truck now sits perfectly level, which is not only better for aesthetics but crucial for maintaining proper headlight alignment and overall vehicle balance.
2. Enhanced Handling & Stability: This was the most surprising and welcome improvement. The truck no longer feels wallowy or unstable on the highway when loaded. It handles bumps, curves, and wind gusts with so much more confidence. The ride is firm and controlled, not harsh or bouncy. It feels like how the truck should have come from the factory for someone who uses it as a truck.
Installation was straightforward. It's a simple bolt-on replacement for the factory bump stops. No drilling, cutting, or complex spring compression is needed. I had it done in my driveway in under an hour.
Final Verdict: If you regularly carry heavy loads, tow, or even just want a more planted and stable ride from your Nissan Frontier, stop looking at expensive, complicated suspension overhauls. The Timbren SES is an incredibly effective, simple, and affordable solution. It does exactly what it promises and does it brilliantly.
Highly recommended!
Perfect fit for my 2023 Nissan Frontier. I have a 3" & 6" extension for my ratchet. 6" is way too long. 3" is almost too short. A 4" extension would have worked better.

I took them off. I didnt like them. They made the unloaded ride too harsh.
