An example of sag on a vehicle's rear axle under a heavy load

Whether you're hauling heavy loads in your bed or cargo area or you're towing a trailer, you will often see the rear of your vehicle sag while the front end rises. In these cases, the rear axle is handling not only the weight of the cargo, but also more of the vehicle's weight. Because less weight is on the front axle, the front tires are making less contact with the road. Overall handling - traction, steering, and braking - is negatively affected. But the resistance from Timbren's Suspension Enhancement System works with your factory suspension to keep your vehicle level and improve your driving experience.


Diagram of the Timbren spring installed

The Timbren system comes with custom-fit brackets that are bolted onto each frame rail above the rear axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down to where the bottom of the spring sits, 1" above the axle. The inch of clearance allows the existing factory suspension to operate normally under light loads and standard terrain, ensuring the smooth, comfortable ride that you are used to.


Animation of a standard Timbren rubber spring

Timbren Suspension Enhancement Systems are designed to work progressively. When the hollow rubber springs are compressed, the convoluted design causes them to quickly collapse along the folds. Once the folds are compacted, the stacked barrel shape increases resistance, stiffening the suspension and keeping your vehicle level.


Timbren suspension system works to prevent body roll

Each hollow rubber spring works independently to support the driver's side or passenger's side of your vehicle. This is helpful when you swerve or make sharp turns. Each spring is activated when it is needed, so body roll is greatly reduced. The independent action also works well when you are hauling off-center loads.


An example of a trailers swaying

Because the vehicle handles better with the springs, less turbulence will be passed along to the trailer, and this helps to keep the trailer in line. Your driving comfort is further enhanced if the trailer does begin to sway (from a gust of wind or a passing semi), because the movement from the trailer is not transferred to your vehicle. This also works to make the sway subside more quickly.


An empty truck on a bumpy road without Timbren

Another great feature of the rubber construction is that the springs absorb most of the road shock, creating a smoother, more stable ride overall when loaded. Wear and tear on the factory suspension is also lessened because the rubber springs work to prevent bottoming out on rough roads.


Timbren Suspension Enhancement Compared to the Competition

Timbren's Suspension Enhancement Systems are much easier to install than air springs - there are no air hoses to run, no compressors or gauges to hook up, and no manual adjustments to make. The rubber construction makes Timbren's springs more elastic than similar products constructed of microcellular urethane. And more elasticity allows for a more comfortable ride when loaded or towing because the rubber has more travel.

I actually found that airbags worked better for my truck and trailer. I ordered those from you as well. May I return the Timbrens for at least partial store credit?

Great product, reasonable price, easy to install and great customer service!



by:

So far so good works great, now let's see how long they last?



by:

Installed this on my 2001 Explorer. Install is easy (assemble unit, bolt on in place of existing bump stop). Annoyed to find it doesn't fit. Specs are gap 1/2"-1-1/2"; there was a gap of 2-3/4". Yeah, they sell spacers for $27 each, but it's really annoying to buy a $225 product that says it fits your truck, only to find that you have to spend 50% more to actually adapt it to your truck!



by:

We put theese on all our trucks they work great if you use your truck to carry heavy payloads or pull trailers .

I never received the item so I canceled and ordered through [online store] I got it the following day. Now, months after I canceled my order, I received this empty box with and note from the mail carrier stating that he delivered an empty box.

  • Recommended Suspension Enhancement For A 2005 GMC Yukon XL Denali
    Hi Arman, The Timbren Rear Suspension Enhancement System # TGMRYS4 are rated for 6,000lbs so they'll definitely help with the sagging, but being as high capacity as they are they'll likely also affect your unloaded ride quality in a negative way. Going with a lower capacity like the SumoSprings Solo Custom Helper Springs # SSR-204-40 (1,000lb load leveling capacity) would help with the sagging without giving you a harsh unloaded ride quality.

  • Recommended Timbrens for a 2002 GMC Yukon XL 1500
    Hey Galen! In order to determine if you need spacers, what size, and how many, you will need to take a couple of measurements. The Timbren Rear Suspension Enhancement System item # TGMRYS4 measures 4-3/4" tall including the puck portion that fits into the cup on the frame. You're going to want 1/2" to 1-1/2" above the axle so that your unloaded ride quality is not changed. The Timbren Front Suspension Enhancement System item # TGMFK15A are 3-9/16" tall, but this kit also includes a 1"...

    The two Timbren rear-axle suspension enhancement kits you referenced, part # TGMRYS4 and part # TGMRG25C, are both fits for the 2002 Chevrolet Tahoe, but kit # TGMRYS4 fits the 2-wheel-drive version while kit # TGMRG25C fits the 4-wheel. Both kits fit vehicles that do not have the Police Package and both install without drilling using included hardware. Both offer 6000-lbs of load support.

  • Recommended Suspension Upgrade for a 2005 GMC Yukon XL
    Hey Charlie! The Timbren item # TGMRSB4S isn't going to be a fit because it only works with the 2500 Yukon's. From what my system tells me the 2005 GMC Yukon XL Denali AWD is a 1500 model. In that case you would need the Timbren item # TGMRYS4. The Timbren item # TGMRYS4 do bolt up where the bump stop used to be. I have linked an installation video below along with the instructions so you can see how easy these are to install. To answer your question though. Yes, the Timbren item # TGMRSB4S...

  • Best Rear Suspension Enhancement Option For 2019 Cadillac Escalade
    Hello Sunny, thanks for reaching out. Our best option for supporting the rear suspension on your 2019 Escalade is the Timbren Rear Suspension Enhancement System # TGMRYS4. These are rubber jounce style springs that install above the axle and engage when you are under a load. These will help to reduce sagging and improve stability, handling, and braking while you tow. They are also a fairly easy no-drill add on. The video linked below will show you an example of installation. Let me know...

  • What Holds Spacer and Timbren Spacer to Chevy Tahoe
    Hey Sean, the spacer and the Timbren spring of the # TGMRYS4 are held in with a bolt to the cup that holds the old jounce spring. You wouldn't want the axle to ride on the spring all the time as that would cause a pretty harsh ride. Normally right around an inch is ideal clearance between the Timbren and the axle.

  • Timbren Springs Not Lining Up with Axle Bracket on 2004 GMC Yukon XL
    Is it the additional spacers that are causing the main part of the spring to out of alignment compared to the stock bump stops on your 2004 GMC Yukon XL? Are the Timbren springs fully seated in the bump stop cups? On these vehicles it is hard to manually push them into place. We usually use a block of wood and slowly put weight back on the axle so that the wood and the weight will push the springs into the bump stop cup. And I know you have the Z71 springs but is the Yukon itself 4-wheel...

    Adding any after market bump stop/jounce bumper could potentially raise the vehicle 1" because they are longer than the factory bump stop however, they are compatible with the Magneride system. Adding them can potentially effect how the vehicle rides when not towing and how the vehicles built in sensors for the air springs read the level of the vehicle.

  • Timbren or Air Lift Coil Springs for 2013 Chevy Suburban 1500 4WD
    For your 2013 Chevy Suburban 1500 with 4-wheel drive, between the Air Lift AirLift 1000 Air Helper Springs # AL60769 and Timbren Rear Suspension Enhancement System # TGMRYS4 I highly recommend going with the Timbrens. The coil springs will not give you the amount of support the Timbrens do, and the Timbrens have another huge advantage in being maintenance-free. Once you install the Timbrens you don't have to worry about them again, while the Air Lift springs are going to require consistent...

  • Recommended Helper Spring Solution for 2014 Chevy Suburban
    Although the Timbren # TGMRYS4 would work for you, I'm not certain you'd be happy with the ride quality you'll experience once the suspension of your Suburban compresses and the preload is taken up which is when the helper springs come into play. The Timbrens offer up to 6000 of additional support which is way more than you'll need to offset the tongue weight of your travel trailer. The SumoSprings # SSR-204-40 add 1000 lbs of additional support, and they're made of a more pliable material...

  • What are the Dimensions of the Timbren Spring # TGMRYS4
    I spoke with my contact over at Timbren about helper springs # TGMRYS4. The overall height of the whole assembly is 4-3/4 inches. The spring by itself is 3-3/4 inches. You'll want an inch to an inch and a half of space between the frame/axle and the Timbren to ensure you ride quality isn't too harsh.

    For air springs on your 2007 Chevy Avalanche, the Air Lift 1000 Air Helper Springs # AL60769 will be the most heavy duty option we currently have available. As the Chevy Avalanche in the 2007 model year has a max towing capacity of 7,200 pounds (when properly equipped), the 1,000 pounds of load leveling support will typically get the job done. However, if you need something more, we do also have the Timbren # TGMRYS4. This will not be an air bag though, so you cannot adjust it when you...

  • Can Air Bags and Rubber Helper Springs Be Installed Together on a 2005 GMC Yukon XL
    The stock bump stops on your 2005 GMC Yukon XL should be located outside of the coil springs so they would not interfere with the AirLift system you installed. You could add some different rubber springs such as # TGMRYS4 but since you already have the air bags installed you would not need to upgrade the bump stops. If they are in bad shape you could get some replacements either from a GM dealer or inquire at a local auto parts store. Or if you want bigger ones you could install the Timbren...

  • Is The Spacer Kit # T68MR Compatible With Timbren Springs # TGMRYS4?
    While the spacers included in the Kit # T68MR will work with your Timbren Springs # TGMRYS4 they do not use the same mounting bolts. Your GMC Yukon uses 3/8" hardware while the spacer kit includes M10 hardware so you would still need to source the longer bolts in your 3/8" thread size.

    A properly rated weight distribution that is set up correctly should eliminate the sag you are experiencing on your 2009 Chevy Suburban. It is possible that the spring bars on your EAZ Lift system are rated too low and thus cannot eliminate the sag. If the trailer tongue weight is 1,000 pounds then the spring bars need to be rated higher than that. A system that is rated for 700 to 1,400 pounds tongue weight, such as # RP66561 would be a great option. You could also add rear helper springs...
