  • 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...

  • 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...

The Timbrens will do a great job of supporting your motorhome's suspension to stabilize it and minimize body roll when taking on tight corners, for example. The Timbrens...

  • Choosing Between SumoSprings or Timbren for 2013 Fleetwood Storm 32BH
  • Although either the # SSR-187-40-1 Sumo Spring or the Timbren # TFRF53A would be a great choice, the Timbren Aeon spring is actually rated higher at 8600 lbs, versus 2600 lbs for the Sumo Springs alternative. Neither of these options will come into play unless the factory suspension gets compressed. If ride quality is the more important consideration, the Sumo Springs option is what I'd recommend as they' give a more supple ride. If reducing roll in the corners is foremost in your mind,...

  • How To Decide Between Standard and HD Roadmaster RAS Leaf Spring Kit for 2018 Chevy Silverado 1500
  • The Roadmaster Active Suspension Custom Leaf Spring Enhancement Kit is an excellent option to provide additional load-leveling support and it will work just fine with an existing weight distribution system. The correct kit for a 2018 Chevrolet Silverado 1500 is part # RAS4611 for standard or part # RAS54FR for heavy duty. The standard would be fine for this application but you could go with the upgraded heavy duty option if you felt the need. Please note, we actually don't carry the...

  • Recommended Suspension Enhancement for 2020 Ford F-350
  • I recommend using the Air Lift LoadLifter 7500 XL Air Helper Springs - Rear Axle # AL55FJ, which will definitely beef up the rear end of your 2020 Ford F-350 and provide you with a fully customizable suspension enhancement. These air bags can be filled up as needed to provide you with as much or little support as you like, so they're especially helpful when you're towing or have a payload in the truck bed. To keep your air bags filled up at all times and give you the ability to constantly...

  • Helper Spring Solution for 2021 Toyota 4Runner Towing 3700 lb Travel Trailer
  • I wasn't able to determine the capacities of the OEM hitch on your 2021 Toyota 4Runner, the only references I could find was to the 500lb TW/5000lb towing capacity of the vehicle itself 'When Properly Equipped'. In the list of equipment needed to achieve that, the 'integrated towing hitch receiver' was mentioned, so it would be a very safe assumption that the hitch capacity would match that of the vehicle. With a loaded weight of 3700 lbs, the tongue weight would range from 370-555...

  • 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)...

  • What is the Difference Between the Roadmaster RAS3611-YHD and RAS3611-Y
  • The difference between the # RAS3611-YHD and the # RAS3611-Y is that the RAS3611-YHD is a heavy duty suspension enhancement designed to provide up to 3000-lbs of leveling and support; the RAS3611-Y is only designed to provide up to 2000-lbs of support. We do recommend the # RAS3611-YHD for trucks carrying heavy loads frequently or those towing heavy 5th wheels and trailers. These kits are easy to install and require no drilling, just attaching some bolts. I've linked a review video we...

  • 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...

  • 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...

  • Which Sumo Spring Product for 2018 GMC 1500 Towing Up To 10,000 lbs
  • Since the SumoSprings will be helping to support the trailer's tongue weight load, ideally you'll want to match the amount of support offered by the SumoSpring to the trailer's tongue weight. Since at most, the tongue weight of your dump trailer will be about 1500 lbs, worst case, I'd go with the 1500 lb capacity, part # SS95MR. When installed, the springs won't quite touch the rear truck axle, so they won't have any effect on your ride except when you're hauling items in the truck bed...

  • 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...

I went out to the warehouse and double-checked these measurements just now. The 1" space for the # TFRTT350J kit is optional and does not have to be installed.

For your 2020 GMC Sierra 2500 HD I recommend the Air Lift LoadLifter 5000 Ultimate Air Helper Springs with Internal Jounce Bumpers # AL88341. The Air Lift LoadLifter 5000 Ultimate Plus # AL89341 is also available with a few upgrades, like stainless steel roll plates which protect the air springs and increase their load capacity by 10 percent.

  • Does Roadmaster Leaf Spring Enhancement Kit Affect Unloaded Ride Height On 2021 Silverado 1500?
  • The Roadmaster Active Suspension Custom Leaf Spring Enhancement Kit for your 2021 Chevrolet Silverado 1500 will not affect the unloaded ride height or ride quality. This system only comes into play when the truck is loaded down; when weight is added to the back of the truck this kit automatically adjusts to keep your truck level and reduce body sway on turns and also enhance braking and traction. When deciding if you should get the Standard Kit # RAS4611 (rated at 2,000lbs) or the Heavy...

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....

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.

  • Differences in Torklift StableLoad Systems And Will They Replace Airbags
  • I wouldn't say that the TorkLift StableLoad Suspension Upgrade w Quick-Disconnect # TLA7310S takes the place of an airbag system and they can definitely be used together with a system like the Firestone Ride-Rite Air Helper Springs # F89ZR. This StableLoad kit simply engages your overload springs sooner, which will help reduce sway. Some differences between these solutions are that airbags are easily adjustable and can adjust side to side to support off center loads. The StableLoads...

  • The TorkLift StableLoad Suspension Upgrade w Quick-Disconnect part # TLA7310S which are a fit for a 2020 Ford F-250 Super Duty would require drilling if you didn't have any pre-drilled holes on the lower overload springs which appears to be the case. I'd suggest the Air Lift LoadLifter 5000 Air Helper Springs part # AL76KV for a no-drill option which gives you much more control.

The main reason is in regards to the construction of the airbags. The Firestone airbags use a crimp rolled design which is much more durable than the band clamp used with the Air Lift counter part.

  • Which Will Have Better Ride Quality for 2020 Chevy Silverado 1500 the RAS Standard Duty or HD

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.

  • Best Suspension Enhancement for 2018 Ford F-150 For Sag and Stability When Towing
  • The best option for suspension enhancement for your 2018 Ford F-150 to help with both sag and stability is definitely the Roadmaster Active Suspension kit over air bags, and there are a number of reasons for that. The reason is the Roadmaster Active Suspension is capable of enhancing your F-150's ride in more ways than air bags while being easier to install and maintain. While both will help with squat, and give you more stability when towing, the RAS will also help your truck with any...

The Hide-A-Goose # 9468-94 does have the highest weight capacity of the available goosenecks for your 2019 F-250, and the air bags are a great addition to keep the back end from sagging while your towing.

The system you'll need will depend on if you have a 2WD or a 4WD truck. The internal jounce bumper feature can be a neat feature to have in the event you have a catastrophic failure of one of the bags, but if that should happen the existing suspension would still provide the necessary support for the short term, so it's not something I'd consider absolutely...

Both of these options will mount in the same place, unfortunately. That being said, the # TDR2500D may be better for your situation than the air bags.

If you're in the rust belt or in or near a marine environment, you'd benefit from the stainless roll plates, hardware and air lines provided by the AirLift LoadLifter 5000 Ultimate Plus, part # AL89341.

  • 2018 Promaster 2500 SumoSpring Recommendation
  • For your 2018 Ram ProMaster 2500 the SumoSprings rear suspension kit you'll need is the part # SSR-313-54. This has the most support at 2,800 lbs which will be ideal since you will be converting your setup to a camper. I'd first try it with both spacers. If you find the ride quality is too harsh then maybe take the one out, but I would be shocked if you didn't prefer the spacers. The springs are most likely going to touch all of the time due to the additional weight you are adding.

  • Will SumoSprings Help Sag With 2020 GMC Sierra 1500 But Keep Ride When Not Towing
  • The SumoSprings will do a fantastic job helping eliminate sag when you are towing with your 2020 GMC Sierra 1500 Denali, and won't affect your smooth ride when you are not towing. The reason is, when installed, if you aren't towing there will be a space between the SumoSpring and your axle and the spring won't come into contact with it. The only time you might feel it slightly is when going over a particularly large bump, but otherwise it won't be noticeable. There are two SumoSprings...

If that's the case, I believe that the AirLift 5000 would be sufficient, as the pin weight of your 5th wheel is very unlikely to be more than 5000 lbs. When you're not towing, the 7500 series would make for harsher ride quality, so I'd go with the 5000. The 7500 series is better suited for folks that...
