• Will RoadActive Suspension For 2019 Toyota Tacoma Give Smoother Ride Than Timbrens
• That's a good question, and the answer is pretty straightforward - yes, the RoadActive Suspension (RAS) is going to give you a smoother, less bumpy ride than the Timbrens for your 2019 Toyota Tacoma. Like you mentioned, the Timbrens do their job well due to the stiffness of their rubber springs, but that stiffness can also cause the ride to be uncomfortable or even jarring as there isn't much give to them. The RAS will absolutely remedy that while providing the same - or better - enhancement...

• Can Two Single Axle Correct Track Kits Be Used in Place of Tandem Axle Kit
• Yes, you can use two of the Correct Track Trailer Alignment and Lift Kit - Single Axle # LC87120 and it will be the same as the tandem axle kit # RR23QX. The tandem axle kit comes with 8 suspension plates and 16 alignment correction plates along with the hardware. Since the # LC87120 has 4 suspension plates and 8 alignment correction plates it would be the same if you ordered two. For leaf springs, you will want to make sure you match the current capacity and length. The length is measured...

• Comparing RAS Leaf Spring Enhancement Kits RAS34FR and RAS4611TD For 2017 Toyota Tundra
• You are correct that there are two RoadActive Suspension Leaf Spring Enhancement Kits for your 2017 Toyota Tundra, the # RAS34FR which has a 3000lb capacity and the # RAS4611TD with a 2000lb capacity. Between these two kits I recommend going with the # RAS34FR as it will give the most support to your suspension. These kits will not negatively affect your unloaded ride so there is not a down side in going with the heavier duty system. With the # RAS34FR you will not only get less squatting,...

• Comparing Timbren Versus Torklift StableLoad For 2019 Ford F-150 Hauling a 5TH Wheel Camping Trailer
• The Timbren # TFR1504E and Torklift StableLoad # TLA7310 both work to reduce suspension sag on your 2019 Ford F-150 in different ways. First the Timbren is a rubber spring that is placed between the frame and axle. When the leaf springs begin to compress the Timbren springs will contact the axle and add additional support to the leaf springs which will reduce sag and provide more stability to the truck. The Torklift StableLoad places a wedge between the curved leaves in your leaf spring...

• How to Correctly Choose Replacement Leaf Springs When Multiple Options Are Available At My Capacity
• The number of leafs on the spring doesn't affect the durability or strength of the leaf spring, so there really isn't a difference between the 6-Leaf Double-Eye Spring for 4,500-lb Trailer Axles - 26" Long # e27SR and the 3-Leaf Double-Eye Spring for 4,000-lb Trailer Axles - 25-1/4" Long # e57SR in that respect. There is a difference in the height of the spring stack and the length, which is where you would want to focus when choosing the correct replacement springs for your trailer. You'll...

• Heavy-Duty or Standard RoadActive Suspension For 2021 GMC Sierra 1500
• That's a good question, and in regards to the standard vs heavy-duty (HD) RoadActive Suspension Kit for your 2021 GMC Sierra 1500, the answer really comes down to the amount of sag, as well as the tongue weight you have. For towing 7,000 lbs you are likely to want to go with the HD. The reason for that is, the HD is best for tongue weight of 600+ lbs or squat of 2+ inches, while the standard duty is for tongue weight under 600 lbs and less than 2 inches of squat. So I do recommend the...

• How is the RAS System Different From Add-A-Leaf System for 2001 Toyota Tundra
• An Add-A-Leaf kit differs from the RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS34FR for your 2001 Toyota Tundra in that the Add-A-Leaf is literally just adding another leaf spring to your spring stack to help make it a little more robust where the RAS system is a little more "smart". It has a spring that helps to provide constant tension and you can adjust it some for more of a relaxed or stiffer ride quality. So instead of just making your leaf spring stack thicker...

• Comparing Air Spring and Leaf Spring Suspension Enhancement for a 2005 Toyota Tacoma
• Since you will be towing a travel trailer, which is a static load that does not change weights all of the time, I recommend going with leaf springs, see link. If you have a 2 wheel drive model that is not a Pre-Runner, go with # SSA1 for 2,000 pound capacity or # SSA7 for 3,000 pound capacity. For a 2 wheel drive Pre-Runner OR a 4 wheel drive model that is not a Pre-Runner, go with # SSA19. Air springs are great if you will be carrying varying load sizes and types so that you can level...

• Differences Between the RoadActive Suspension Systems For a 2022 GMC Sierra 2500
• There are currently 3 kits available for your 2022 GMC Sierra 2500. The correct kit will depend on the leaf springs under your Sierra and the amount of sag you are experiencing. Do note that none of these systems will increase your payload or towing capacity. They will only provide assistance to your factory suspension giving you a more level and safe ride. The first kit is the RAS System # RAS3611. This system is rated for a capacity of 2,000lbs and works best with trucks that squat...

• RoadActive Suspension Over Sumo Springs for a 2018 Chevy Silverado 2500
• For your 2018 Chevy Silverado 2500 I would go with the RoadActive Suspension Custom Leaf Spring Enhancement Kit - Heavy Duty item # RAS3611-HD over Sumo Springs. The RAS system has a 3,000 lbs weight capacity that will level out your rear end. The best part about the RAS system is that it can be disengaged when you're not towing, allowing your leaf springs to perform as intended. Sumo Springs do not have this feature and can often times provide a stiff ride when you are not towing.

• Roadmaster Trailer Suspension Upgrade Kit for 2017 Grand Design Solitude
• The Lippert Center Point Air-Ride Trailer Suspension Upgrade # LC1565391 will help reduce shocks transmitted into the chassis of a trailer that has a tandem axle double-eye leaf spring suspension, but this kit also raises the trailer height by 2-inches. This is something to consider since raising the trailer's center of gravity can lead to more sway. For this reason I would go with the Roadmaster Comfort Ride kit # RM-2460-2570. This will support and dampen motion of your 7K axles with...

• RoadActive vs. SuperSprings For 2018 Ford F-150 4x4 Towing Trailer
• For your 2018 Ford F-150 4x4, the better option between the RoadActive and SuperSprings # SSA28 is the former, the RoadActive, because it provides more benefit, such as eliminating axle wrap and wheel hop (which is when the tires lose their grip due to a heavy load causing the leaf springs to twist). Additionally, the RoadActive is more customizable with a pair of different kits with different weight capacities depending on how much sag you have: - 2,000 lb Capacity & Up To 1" of Sag:...

• Air Bags vs RoadActive Suspension Leaf Spring Kit for 2004 GMC Sierra 1500 Towing Boat
• Both the Firestone # F2320 SportRide and the RoadActive Suspension (RAS) # RAS54FR will provide support for the rear suspension to help counteract the sag in the rear suspension that occurs when a trailer's tongue weight is applied. However, the RAS will also improve stability and control by eliminating axle wrap, reducing sway and body roll and improve traction during acceleration and braking. The system will only affect the vehicle's ride when the rear suspension is under load and unlike...

• Comparing Firestone Air Bags and SuperSprings for a 2020 Ford F-250 Super Duty
• The main difference between air bags like the Firestone Ride-Rite Air Helper Springs part # F35FV and add-a-leaf like the SuperSprings Custom Suspension Stabilizer part # SSA22 is that the air bags can be adjusted to a particular trailer or load and the add-a-leaf options are not adjustable. That said, they are both great options for a 2020 Ford F-250 Super Duty. The Titan Chain Alloy Snow Tire Chains part # TC2533 fit both 275/70-18 and 285/65-18 tires.

• Comparing Leaf Spring Axles, Torsion Axles, Dexter and Hayes/AL-KO
• I personally would not have any reservations about using a torsion axle. Dexter is a leader in the industry but Hayes/AL-KO are quality as well. It seems to be easier to get parts for Dexter axles and they tend to cost less. On a torsion axle you will want to be cautious not to overload it (of course this goes with leaf spring axles too). The suspension components on leaf spring axles are easier to replace as well but a torsion axle is going to give you good performance provided you keep...

• What Is the Difference Between RoadActive Suspension Kits for 2016 Toyota Tacoma 4WD?
• The difference between the RoadActive Suspension Kit # RAS4514-SAT and the # RAS4524-SAT is more than price. The # RAS4514-SAT is intended for vehicles in which the axle is located below the leaf springs and the # RAS4524-SAT is intended for vehicles in which the axle is located above the leaf springs. They look almost identical uninstalled, but the installation and function is different.

• Differences Between K Source Custom Towing Mirrors, Recommended Sway Control For '03 Chevy Avalanche
• The only difference is K Source Custom Towing Mirrors, part # KS62075-76G have LED turn signals and # KS62075-76GE do not. Other than that they are the same product. Air Helper Springs, like The Firestone Ride-Rite # F4108, will help control sway on rough terrain, but the main purpose of air helper springs is to keep your vehicle level when hauling heavy loads and level off-center loads. Since you already have a weight distribution system with sway control and feel like you need more...
