  • Sumo Springs Versus Timbren Suspension Enhancement For 2019 Jayco Precept 31UL 22,000#
  • While both the Timbren Suspension Enhancement System # TFFF53B & # TFRF53A and the SumoSprings Rebel Custom Helper Springs # SSF-170-40-2 & # SSR-180-54-1 are both great solutions for your 2019 Jayco Precept 31UL, there are some differences to take note of. Timbren is a bit more renown in this space and while a very solid product, that strength comes with the tradeoff that the ride quality can be stiff. Made from a rigid rubber construction, it can be less forgiving and this has been...

  • TorkLift StableLoad Vs. Timbren for 2020 Ford F-350 Super Duty
  • I talked to some of our guys down in our installation bays and based on the feedback I received, I definitely recommend the Timbren Suspension Enhancement System # TFR350SDJ for your 2020 Ford F-350 Super Duty. The TorkLift StableLoad # TLA7310S work by engaging your factory lower overload springs earlier than they would otherwise, which minimize sway and assist you when hauling heavy loads. However, disengaging this system requires you to get under the truck and use a rachet (not included)...

  • Suspension Enhancement Option For 2017 Ford Expedition
  • I do have an option for you but the Air Lift AirLift 1000 Air Helper Springs for Coil Springs you mentioned are designed for Dodge trucks so they are not compatible with the 2017 Ford Expedition. Instead, I recommend the Coil SumoSprings Custom Helper Springs for Coil Spring Suspension part # CSS-1168 which is a great option to support the coil springs of the Expedition to avoid rear sag that you may be experiencing. There are currently not any other options available for the Expedition...

  • Difference Between Firestone 7500 and Air Lift 7500 for 2020 GMC Sierra 3500
  • The air spring kit I recommend for your 2020 GMC Sierra 3500 is the Firestone Ride-Rite Red Label # F2709. Firestone air bags are less likely to leak and overall more reliable thanks to their rolled crimp seal that keeps the bags securely anchored to the metal end plates. This is superior to the standard band style clamp designed used on the Air Lift bags, like the LoadLifter 7500 XL Air Helper Springs # AL57541. Another advantage of the Firestone kit is that it gives you the option...

  • How do I Pick the Right Roadmaster Active Suspension Enhancement Kit for my 2018 Ford F-150
  • We can get this figured out! The weight capacities stated in the description is the amount of weight that these springs will support. These will not add capacity to your payload or the amount you carry but instead take some of the force off of your factory suspension decreasing wear and tear on the system helping it to last longer. In my experience it also helps the handling characteristics of the vehicle by reducing the body roll of the truck. The Roadmaster Active Suspension Custom...

  • Differences Between AirLift and Firestone Helper Airbags For a 2019 Ram 2500
  • I recommend the Firestone 7,500 lb Ride-Rite Label Air Helper Springs part # F2706 for the 2019 Ram 2500 because of their durability compared to the Air Ride Helper Springs part # AL57589. Both of the brands have a 7,500 lb capacity like you mention however they are constructed differently. The Firestone bags are constructed of 4 layers of rubber compared to the 2 layers of the Air Lift springs. The Firestone bags also use a crimp rolled seal to keep the bags anchored compared to the Air...

  • The Air Lift air bags for the 2019 Thor ACE motorhome 27.2 part # AL88240 for the front axle and part # AL88344 for the rear are a great option for suspension enhancement however they do require some upkeep so they are not easier. I recommend to use the SumoSprings part # SSF-170-40-2 for the front axle and part # SSR-187-40-1 for the rear axle. The SumoSprings are easier to install and do not require any upkeep. They are basically an install it and forget it suspension enhancement....

  • Recommended Jounce Springs for Two-Wheel Drive 2019 Ford F-53 Chassis
  • The jounce springs I recommend for your two wheel drive 2019 Ford F-53 chassis are from SumoSprings, the SumoSprings Rebel for the front axle and SumoSprings Maxim for the rear axle. The reason why the SumoSprings are the best is because they not only work to reduce sway, but also keep your vehicle level and give you a smoother ride. The SumoSprings can do this because they are made of a microcellular urethane which compresses. Each of the springs works independently which is what is...

  • Best Suspension Enhancement for 2017 Ford F-150 to Reduce Towing Suspension Sag
  • The RAS systems are by far the best suspension enhancement kits out there for vehicles like your 2017 Ford F-150 to reduce suspension sag. Main reason is that unlike other system this does not make your ride quality when loaded or unloaded (many state that the ride quality improves greatly) and also does not require the maintenance that air bags do as well. For as much as you plan on towing I'd go with the HD model part # RAS3611-YHD which gives 3,000 lbs of suspension support over the...

  • How to Choose the Correct Timbren Rear Suspension Enhancement for a 2019 Ram 1500
  • If you have a 2019 Ram 1500 that is the standard pick-up truck, the correct Timbren system is the Timbren Rear Suspension Enhancement System # TDR1500DQ, which were designed for standard trucks. The difference between these and the Timbren System # TDRTT1500 is that the latter is made for service trucks, like a tow truck. The reason for this is the design of the springs; if you take a look at the accompanying photo a customer sent in, you can see they are double convoluted, which means...

  • Comparing the Timbren SES Part TFR350SDJ and Part TFR250SDJ for a Ford F-250/F-250
  • The Timbren Suspension Enhancement System part # TFR350SDJ is correct for your 2017 Ford F-350 whereas the Timbren Suspension Enhancement System part # TFR250SDJ is for a 2017-2019 Ford F-250. The brackets on both of these systems are the same so you can use one on the other but the F-250 kit has a 4-1/2" tall spring whereas the F-350 kit has a 5-3/16" tall spring. Therefore, the F-250 kit will not engage as soon as the F-350 kit when used on a F-350. The later engagement will equate to...

  • Which Will Have Better Ride Quality for 2020 Chevy Silverado 1500 the RAS Standard Duty or HD
  • If you are worried about ride quality I would go with the lower rated # RAS4611 over the higher rated # RAS54FR for your 2020 Chevy Silverado 1500 4x4. Both will work great but the lower rated one will be easier to fine tune the amount of support and ride quality you want without having to give up too much on either end.

  • Is Weight Distribution Needed With Suspension Enhancement on 2018 Toyota Tacoma?
  • Those are very good questions and let's start with the capacities of both systems. The SumoSprings Solo Custom Helper Springs # SSR-612-40 has a 500 lb capacity and SumoSprings # SSR-612-47 has a 1,000 lb capacity, which means that is the highest amount of weight that the springs will actively still help your 2018 Toyota Tacoma's suspension. Anything over that and you won't see the benefits of the system. If 3,500 lbs is the max weight of your enclosed trailer when it is loaded then...

The first reason is that the Air Lift kit requires drilling into the frame (minimal) whereas the Firestone kit is completely drill free. The second reason is in regards to the construction of the airbags. The Firestone airbags use a crimp rolled design which is...

For your 2020 GMC Sierra 2500 HD I recommend the Air Lift LoadLifter 5000 Ultimate Air Helper Springs with Internal Jounce Bumpers # AL88341.

  • Axle Bracket Extension Kit for Lifted 2012 Toyota Tacoma
  • The correct spacer you will need for the Firestone Ride-Rite Air Helper Springs part # F2407 on your 2012 Toyota Tacoma is actually going to be the Firestone Axle Bracket Extension Kit part # F2506. These will then bolt to the side of the vertical support on the lower bracket. If they are too long then you can just trim them but the Firestone Ride-Rite Axle Spacer Brackets for Lifted Vehicles part # F5557 and part # F5558 won't be your best options.

  • Is a Lift Spacer Required for Air Lift Airbags on a Lifted 2017 Ford F-250

In your case, you are correct in that you will not need a lift spacer to install the Air Lift LoadLifter 7500 XL Air Helper Springs part # AL57577 on your 2017 Ford F-250 as the distance between the contact point and jounce spring has not changed. This is the case for most newer Ford trucks with lift kits installed. In order to take full advantage of these airbags you might also want to consider an air compressor system like the Air Lift WirelessAIR Compressor...

  • Rear Suspension Enhancement Recommendation for 2007 Toyota Tundra
  • If you still are experiencing sag with the weight distribution system that can mean a few things. Either the system is rated too low, the system isn't setup properly, or the vehicle is being overloaded. While we can help you pick out suspension enhancement I'd first verify those three things. You want to make sure the loaded tongue weight of your system falls right in the middle of the range of your setup. For suspension enhancement for your 2007 Toyota Tundra that will help the most...

  • I'd be happy to help you determine what Air Lift air bag kit to use on your 2019 Ram 1500! The selection can basically be divided up into 2 categories; air bags that install inside your suspension springs and air bags that install in place of your factory bump stop. The kit that installs in your springs, part # AL60828HD, is more of a cost-effective air bag kit and while it serves a purpose, if you are going to be using the air bags quite a bit it is not what you want to go with.

The lighter springs will give you a lift of 3/4 inch while the # SSC-51 will give you a lift of right at 2 inches and will be much harsher. If your factory suspension handled everything well before adding the solar system I'd go with the lighter duty springs. If not I'd recommend the heavier duty setup. More is always...

The severe duty # TFR250SDJ is 3-5/8 inches tall and has the same bracket height of 2-3/8 inches plus a 1 inch spacer. Timbren states that once a system is installed you will need 1/2 inch to 1-1/2 inches of space between the bottoms of the springs and the top of the axle. So that's why the higher...

  • Recommended Suspension Enhancement for a 2019 Mercedes-Benz Sprinter 3500
  • I recommend using the SuperSprings SumoSprings for your 2019 Mercedes-Benz Sprinter 3500. These are a one-time installation that you never have to worry about checking up on and they provide more support (become more rigid) as you load more things into your Sprinter. For the front axle you need the kit # SSF-106-47 and then for the rear you need the kit # SSR-338-54. The SumoSprings are superior to the other suspension enhancement options because they tend to provide more cushion so...

  • Comparing Timbren and SumoSprings Suspension Enhancement for 2019 Thor ACE 30.2 Motorhome
  • The biggest difference between the two for your 2019 Thor ACE 30.2 motorhome, and the reason why I highly recommend the SumoSprings over the Timbren, is what each product is constructed from. The Timbrens are made from a strong, rigid rubber while the SumoSprings are made from microcellular urethane. This is important because it means the SumoSprings will compress more gently, while the Timbrens are known to give a much stiffer ride. The front axle and rear axle fits for your 2019 Thor...

Timbren is a little more well-known but we have received feedback from our customers that the SumoSprings offer better ride quality as they aren't as stiff.

What I recommend is getting the truck loaded up and the trailer coupled and then adding however much air is needed to the air bags.

The single-convoluted springs are designed for service vehicles like tow trucks because they have less travel - they won't compress as much - than double-convoluted springs, making them more rigid for heavier-duty work. Due to this I highly recommend...

  • Air Bag and Compressor Kit Recommendation for 2020 Ford F-350
  • The best air bag kit we have for your 2020 Ford F-350 is the Firestone kit part # F2605 if you have a single rear wheel axle or # F2604 for if you have a dually. The Firestone bags are just higher quality than the competition. Mainly due to them being 4-ply vs. others being only 2-ply. Unlike other kits these are also compatible with in-bed hitches like fifth wheels and goosenecks. For a compressor kit then the heavy duty part # F2097 will make inflating the bags and maintaining them...

  • SumoSprings will definitely help to improve the ride of your 2018 Forest River FR3 29DS. For your Ford F-53 chassis with an 18,000 lb GVWR you want part # SSF-170-40-2 for the front axle and part # SSR-184-40-1 for the rear axle. The two greatest things about about the SumoSprings is that they do not require drilling for the installation and once the installation is complete there is no maintenance that needs to be done. You can also install Front # RM-1139-140 and Rear # RM-1139-146...

  • The main difference between the Timbren Rear Suspension Enhancement System part # TGMRCK15S and SumoSprings Solo Custom Helper Spring part # SS45FR for a 2019 Chevrolet Silverado 1500 is hardness. The Timbrens are much denser than the SumoSprings so although they will provide more support, they will also produce a rougher ride. I recommend the SumoSprings since it does not sound like you will be towing everyday and still need the truck to have a factory-like ride quality most of the time...

  • Is the Timbren Suspension System Or Torklift Stable Load Better for 2020 Ford F-350 With Rear Sag
  • I recommend to use the Timbren Suspension Enhancement System - Rear Axle part # TFR350SDJ which will give you more stability to reduce rear sag. The springs provide the additional support under heavier loads that your factory suspension cannot provide. The TorkLift StableLoad Suspension Upgrade w Quick-Disconnect part # TLA7310S does help to support the lower overload springs and eliminate body roll but they won't fix the rear sag.

  • Jounce-style springs like the SumoSprings # SSR-117-47 you referenced for the rear axle of your 2018 Ford F-150 do a great job of allowing your truck to better support heavier loads, but they aren't going to eliminate sag. This is because there's still going to be a gap between the spring and axle, meaning the rear of the truck will need to drop a bit before they will even engage. Since you aren't a fan of the idea of air bags, your best solution for maintaining a level ride when under...
