Timbren Rear Suspension System Installation - 2016 Chevrolet Silverado 2500

Today on our 2016 Chevrolet Silverado 2500, we're going to take a look at and show you how to install the Timbren rear suspension enhancement system, part number TGMRCK25D. Before we start any changes, let's go ahead and get some measurements, so we know where our starting point is. It looks like here in the rear it's going to be forty-three inches to the inside of our fender well. Now let's check the front. Here in the front, we've got about forty. Now we've added in about two hundred gallons of water, just to simulate a heavy load in the truck. Now here in the back, we're looking at about forty and a quarter, so we've come down considerably. As you can imagine, this is putting some excess stress on our rear suspension system, excess stress on the rear tires.


Firestone Ride-Rite Air Helper Springs Installation - 2000 Ford F-250 Super Duty

Today on our 2000 Ford F250, we'll be taking a look at and installing the Firestone Ride Rite Air Helper Springs, part number F2550. The first thing we're going to do before we start our installation is go ahead and check out our factory ride height on the rear as well as the ride height on the front. It looks like we're going to be right at about 41-1/8". We'll go ahead and put some weight in the back of our truck now to see how it differs. Now with some weight in the back of our truck, we're going to check that distance again. It looks like we came down to about 39-1/4". The rear has dropped 2". Now, we're going to go ahead and put some air in our air bags.


Timbren Rear Suspension Enhancement System Installation - 2009 Chevrolet Silverado

Today on our 2009 Chevrolet Silverado we are going to show you how to install the Timbren Rear Suspension Enhancement System, part number is TGMRCK35S. Here you can see our Timbren installed. It is going to give us a nice fuller stop here, our actual jounce stop, or jounce bumper was only about this long. This is going to allow us, with no contact here, to have no real change in the unloading handling of our vehicle. As we apply our load it is going to bring this down and it is going to rest on those jounce stops. That's going to give us improved suspension.


Roadmaster Active Suspension Kit Review

Today, we're going to take a look at the Roadmaster Active Suspension Kit, part number RAS3611. The Roadmaster Active Suspension Kit is going to help to convert our basic leaf spring kit into a mechanically active suspension. This is going to provide great assist for vehicles with the rear leaf springs without compromising any of their ride quality. It's going to help to eliminate any of the bottoming out or axle wrap that we can sometimes get, which is going to lead to great improvements and road handling. It helps to reduce the sway and the body roll that we often we get during cornering. The Roadmaster Active Suspension Kit works with or without a load. It's going to absorb and dissipate any load force that we might have when our vehicle is loaded, and whether it's loaded or unloaded, we're going to have improved vehicle stability, handling, traction, and control.


Firestone Ride-Rite Air Helper Springs Installation - 2016 Ford F-350

Today on our 2016 Ford F350 we're going to take a look at and show you how to install the Firestone Ride-Rite Air Helper Springs. These air bags are double convoluted and they're designed for the rear axle. Part number is F2535. By allowing our air bags to take some of that weight off the rear suspension of the truck it's going to increase the longevity that we'll get out of our leaf springs and also reduces friction. This is also going to soften the contact between the axle and the frame so even with heavy loads we're not going to have to worry about bottoming out. Here you can see the included bracket. That's going to hold both our inflation valves in place for us up here in safe location that we won't have to worry about them ever getting snagged. The added benefit that we get from the dual inflation valve is side to side load leveling.


Firestone Level Command Compressor Installation - 2016 Ford F-350

Today on our 2016 Ford F-350, we're going to take a look at and show you how to install the Firestone Air Command Heavy Duty Compressor with analog gauge. This is a single function compressor with a maximum air pressure of 150 PSI. Part number is F2097. Here's what our gauge pack is going to look like installed. This is a really nice kit. This is going to show us exactly how much pressure that we have in our air bags. If we need to add some, simply press up on the switch.


Firestone Ride-Rite Air Helper Springs Installation - 2016 Ford F-250

Today on our 2016 Ford F-250 we're going to take a look at and show you how to install the Firestone Ride Rite double convoluted air helper springs. These are for the rear axle. Part number is F2535. Now the first thing we're going to do is determine our factory rise height. That's going to be from the ground to the inside top edge of our wheel well opening where we're going to measure. Here on the rear we got about 41 and half and it looks like here in the front we're going to have about 40 and three quarters of an inch.


Air Lift LoadLifter 5000 Air Helper Springs Installation - 2015 Ford F-450

Today on our 2015 Ford F-450, we'll be taking a look at and installing the Air Lift LoadLifter 5000 Ultimate Air Helper Springs with Internal Jounce Bumpers, part number AL88349. This is specifically designed for vehicles with a square axle. All right, and this is what our kit's going to look like. We're going to have 2 sets of all of this here. We'll have 4 of those long carriage bolts, 2 of the short carriage bolts, 8 of these little bolts, and all the hardware to go with them, flat washers, lock washers, and everything you'll need. You'll also have 4 of the cups or plates that have 3 holes in the bottom, and the rounded edge.

Vehicle Suspension Questions and Answers

  • How To Tell What Size Firestone Lift Spacers Are Needed On A Truck With A 6 Inch Lift Kit
  • To determine what size lift spacer to use on your vehicle with Firestone Ride-Rite Air Springs, measure the distance between the upper and lower brackets of your air helper spring kit, and whether the kit mounts on the leaf spring or the axle. The spacer needs to be the same length as the amount of lift applied to the axle on which the air helper spring is installed. The axle mount kit would have the lower bracket mounted to the axle. The leaf mount kit would have the lower bracket mounted...

  • Recommended Air Pressure of Firestone Ride Rite Air Springs # F2071 on Dodge Ram 3500 Dually
  • Other than saying that the air bags need to be kept between 5 and 100 psi, Firestone does not offer much in the way of specifics. The instructions mention that as a general rule of thumb, 1 psi will support approximately 40 lbs of load. Your best bet is to use enough pressure to level the vehicle, and then adjust plus or minus according to your personal preference. You can do this with the 5th wheel in place, and for the unloaded scenario. Keep in mind that using an air bag suspension...

  • Firestone Air Bag Suspension Enhancement for a 2014 Chevy Silverado LTZ Z71
  • The axle your version of the 2014 Chevy Silverado would be the Z71 rear axle and that should also be a 4 wheel drive model. The proper kit for a 1500 would be # F2430 that you have referenced. But if it happens to be a 2500 or 3500 then you would need to use # F2528. I have linked videos to the right showing typical installations for you. Also, if you do not want to manually fill the air bags every time you can install a Level Command II kit, # F2219, which will allow you to fill/remove...

  • Suspension Enhancement Recommendation for a 2011 Dodge Ram 1500 Towing a Gooseneck Trailer
  • For occasional towing with your 2011 Dodge Ram 1500, I would go with the Timbren suspension enhancement system. If you do not have a Quad Cab, use # TDR1500DS. If you do have a Quad Cab, use # TDR1500DQ (instructions linked for reference). The Firestone systems are good when you carrying varying sized loads and have to adjust the ride accordingly. But for occasional towing of the same trailer, the Timbren system would be the way to go.

  • Air Lift or Helper Spring Recommendation for a 2000 Ford F-250 Super Duty Towing a Camper Trailer
  • The product that will work best for you will depend on how you will be using your truck and why you are looking for a suspension enhancement system. If you are looking to level your truck because you do a lot of hauling with varying load weights and tow the trailer occasionally then the air bags would work well. I would recommend using the Air Lift LoadLifter air springs, # AL57298, for 2 wheel drive or, # AL57390 for 4 wheel drive models of the 2000 F250. I recommend these air bags...

  • High Capacity Suspension Enhancement for a 2012 Dodge Ram 1500
  • The frame and suspension is different between the 1500 and 2500 series 2012 Dodge Ram so the parts are not interchangeable. But if you want the most capacity for a 1500, take a look at the Timbren springs # TDRTT1500. These guys are rated for 7,000 pounds and would be ideal for beefing up your suspension. The Timbren springs will provide leveling support independently of each other, increase stability and ride quality, and reduce side to side body roll. I have included a link to an...

This is the most the vehicle, including cargo and occupants, plus the trailer can weigh. This information is usually in the owners manual or on a sticker in the door jamb. Looking at an online copy of the owners manual the 4 liter V6 model of the 2013 Toyota Tacoma with 4-wheel drive could have one of several capacities depending...

  • Differences Between Firestone Ride Rite Air Helper Spring Kits # F2542 and # F2525
  • According to my Firestone representative, the only difference between the # F2542 and the # F2525 is that the mounting brackets on the F2542 are a bit different to allow a B and W fifth wheel hitch or a fifth wheel hitch with the # RP30035 universal brackets to be installed. The Firestone # F2525 would not be compatible with frame brackets for a fifth wheel hitch.

  • Air Helper Spring Kit Recommendation for a 2015 Ford F250 Super Duty 4x4

The Air Lift Loadlifter 5000 part # AL88396 would be a great choice for you as it has been confirmed to fit your vehicle. I attached an install video for you to check out as well.

The # TDRTT1500, system is rated at 7,000-lb capacity and considered a severe service application. It was designed for tow truck, dump truck, and trucks that will use a slide-in camper, and have a weight in the bed a majority of the time.

  • How to Reduce Sag on a 2012 Ford F-250 Super Duty with Towing a 5th Wheel Trailer
  • The best way to reduce the sag on your 2012 Ford F-250 when towing your fifth wheel trailer is to add a rear suspension enhancement system. The two most common types of rear suspension enhancement systems are air bag systems and rubber spring systems. The rubber spring systems like the SumoSprings and the Timbren Springs, # TFR250SDG, are typically more economical than an air bag kit like the Firestone Ride-Rite Air Springs, # F2550. The Timbren springs and the Ride-Rite kit that I mentioned...

There is not much of a difference between the Ride-Rite Kits, # F2550, that I recommended and # F2484 that you referenced, but the brackets that are included with the # F2550 springs are compatible with fifth wheel and gooseneck trailer hitches. It may not seem that important now if you do not have a gooseneck or fifth wheel hitch, but the # F2550 air springs will...

I have included a link to a video showing a typical installation of this system. As you can see the truck in the video also has rear coil springs. I have also included a link to the installation instructions for you.

The Air Lift compressor kit and the Ride-Rite both use 1/4 inch air lines and fittings so they are compatible with each other. I have attached the installation instructions for the Air Lift compressor kit for you to check out. I would also recommend picking up the Air Lift Air Hose Cutter, #...

The Timbren springs are designed to do exactly what you need plus they will reduce side to side body roll, absorb road shock, and will not affect the empty ride of the vehicle. When you have a load in the bed, like your 5th wheel trailer, the bed will drop and what the Timbren springs do is take of the gap between the axle and frame more than the factory bump stops. This is what...

  • Fit of Firestone # F2535 Ride Rite Air Helper Springs on 2015 Ford F350
  • Is it possible that your 2013 F250 was a Diesel and your 2015 F350 has a gas engine? If that's the case, it would explain the difficulties you're having. The # F2535 is intended for Diesel engine vehicles, while the # F2550 is for Gas engines. The only difference between the two kits is the brackets. To fit the # F2535 to your 2015 F350, you'd need a new bracket for the driver's side, part # F5572.

Please note that you should always have at least 5 psi in the springs up to 100 psi. When in its regular state the bags will not expand much beyond how they come in the box. They are 6 inches tall again not counting the valves. And finally, the diameter is 5-3/4 inches. Use these measurements as guides...
