Note: SuperCoils should be installed by a qualified installer or technician.

Hauling heavy cargo or pulling a trailer can cause the rear of your vehicle to sag while the front end rises. This means that the rear axle is handling the full weight of the load plus your truck's weight as well. The lighter weight on the front axle means that the front tires make less contact with the road, causing problems with traction, steering and braking. With SuperCoils helping to more evenly distribute the weight of your load, your tires make better contact with the road and your driving control greatly improves. These beefy coils replace your OEM coil springs to help your rear end bear up under the load, evening out the weight. They help to lift the rear end and make driving easier and safer.

SuperCoils are a maintenance-free solution to the sagging caused by hauling and towing heavy loads.

Review from a similar SuperCoils in Vehicle Suspension

Great service and delivery time. I installed these front coil springs in my 99 ford diesel Superduty. After years of the old springs sagging and the ride quality degraded, the new springs picked the front end back up and now the truck drive wonderfully. These springs work with or without ranch bumper. I will return.

-- comment by: Tom - 10/01/2013

Jeff, did you get a 1.5 inch lift from the supercoils or do you think they just brought your front end back to stock ride height? Did you upgrade yout shocks as well with a longer shock?Thanks
-- comment by: Lee - 04/10/2014
Lee, The springs worked great. I complimented them with standard length Bilstien shocks and made it ride even better while setting the front end back up to stock height. If you have a heavy aftermarket front bumpergrill guard or snow plow then I would probably get the heavier duty 5000lbs springs.

Review from a similar SuperCoils in Vehicle Suspension

I installed the ssc-30 springs on my 96f350 2wd to replace my old worn out factory springs. The bottom on the coil was too big for the bottom hold down retainer plate, so I had to make a new oversized retainer. Then the springs picked the truck up so much that with 4°camber bushings, i was still 3° out. After installing a 2in pivot bracket drop, I think I finally got it right. I love the way it looks, but I didn't expect it take so much to get it right


Review from a similar SuperCoils in Vehicle Suspension

These springs are awesome!! Before iinstalled the new heavy duty front coil springs, the front of my truck used to sag and bottom out constantly.
Now it sits level, rolls less in turns, brake dip is almost non existent.
It never bottoms out any more, these springs are excellent!


Review from a similar SuperCoils in Vehicle Suspension

Great customer service. Great website and informational. Stabilized a 1500 with a heavy lift gate. Kept us from buying a 2500 at this time.

Our 1500 Ram with a hydraulic lift gate is still holding up to daily abuse. I was told that I needed to step up to 2500, but did not have the means as a company at the time. Our crew cab Ram 1500 doesnt bend the knew to any load.

Review from a similar SuperCoils in Vehicle Suspension

Barely raised the front end. Exactly what I was looking for. They feel amazing.


Review from a similar SuperCoils in Vehicle Suspension

I wanted to beef up my 97 Dodge 2500, to be able to carry two bikes on the front of my Ranch bumper. Also have a Northen Lite camper. Helps maintain weight control. The springs make a huge difference in the way the truck handles, especially when driving over bad roads.


Review from a similar SuperCoils in Vehicle Suspension

I had old ones before and didn’t realize how bad my rv needed new ones. Can’t begin to express the importance of having good quality parts on your coach. Highly recommend.


Review from a similar SuperCoils in Vehicle Suspension

  • Rear Suspension Enhancement Recommendation for 2018 Ram 1500 Short Bed
    The replacement rear SuperCoils part # SSC-50 that you referenced is the way to go to beef up the rear suspension of your 2018 Ram 1500. This will give you the additional support you are looking for but also won't affect the ride quality like some of the other options.

  • Recommended SuperCoils Custom Suspension Coils for 2018 Ram 1500 With 5K Trailer
    The SuperCoils Custom Suspension Coils part # SSC-50 which are a fit for a 2018 Ram 1500 will offer plenty of support while towing without jacking up the rear of the truck too high while unloaded. That said, it will take a few days for the coils to settle so don't be too alarmed if the truck sits higher than you'd like after first installed.

  • Does SuperSprings # SSC-50 Fit 2020 Ram Rebel and Affect Suspension Height

  • What Is The Spring Rate Of SuperSprings SuperCoils SSC-50 For 2019 Ram 1500 Classic?
    I reached out to my contact at SuperSprings and the SuperCoils Custom Suspension Coils - Rear Axle # SSC-50 you were looking at for your 2019 Ram 1500 Classic has a spring rate of 240lbs which is pretty close to what you were calculating. Since these springs add 2058lbs of load leveling support to the rear suspension of your truck these are a great option to further decrease sag when towing your 7500lb travel trailer with 769lbs of tongue weight. Keep in mind that with these springs the...

  • How to Pick Out SuperCoils Springs for 2017 Ram 1500
    There are two Supercoil options for your 2017 Ram 1500. We have the part # SSC-50 which has a 475 lb capacity and the part # SSC-51 which has a much higher 2,480 lb capacity. 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...

  • Choosing Between Upgraded Rear Coil Springs for 2019 Ram 1500 Classic
    In light of replacing the rear coil springs on a 2019 Ram 1500 Classic for towing you have two options, the SuperCoils Custom Suspension Coils part # SSC-50 which has a 2,058 lb weight capacity and part # SSC-51 which has a 2,480 lb weight capacity. These are the total weight capacity per coil and not in addition to the factory coil springs which are rated much lower. I recommend the SuperCoils Custom Suspension Coils part # SSC-50 as this will be the perfect option for both support and...

  • Recommended Suspension Enhancement for a 2021 RAM 1500 Sport
    Though the SuperCoils # SSC-50 will fit a 2021 Ram 1500 and 1500 Classic, they are not adjustable. With that, the ride will be affected when not towing. If you are towing most of the time, however, these will still be a good option. That being said, I prefer the adjustability of the Firestone Coil-to-Air-Spring Conversion Kit # F2595. These can filled from 5 psi at the low end, up to 100 psi at the high end. This translates to being as close to the stock ride as possible when not towing,...

  • Which Rear Suspension Enhancement For 2019 Ram 1500 Towing 34' Travel Trailer
    There are a few options to help support the suspension on your 2019 Ram 1500 when you are towing. As long as your factory shocks are in good shape you will not need to replace them. The SumoSprings Solo Custom Helper Springs # SSR-307-47 will be able to help support the weight on your truck, and when you are just driving without the trailer will have a smooth ride. Since you mentioned having quite a bit of sag I would recommend the SuperCoils Custom Suspension Coils # SSC-50 which replaces...

  • Best Rear Suspension Enhancement For 2022 Ram 1500
    I recommend using the SumoSprings Solo Custom Helper Springs - Rear Axle item # SSR-307-47 to address sag in your 2022 Ram 1500. Timbrens will offer you a rough unforgiving ride and are typically only recommended when there are no other options or on work trucks with service beds. The SumoSprings will help with the weight put on the rear of your truck when towing but you will not notice them during daily driving. Another way to address sag are the SuperCoils Custom Suspension Coils item...

  • Suspension Enhancement for 5th Towing Using 2022 Ram 1500 with 6-1/2 Bed
    For your situation of using a 2022 Ram 1500 with 6-1/2' bed to haul a 5th wheel RV, enhancing the suspension is a good call. My recommendation is to use the Air Lift LoadLifter 5000 Ultimate Air Helper Springs with Internal Jounce Bumpers, # AL88375. The air springs and jounce springs in this system work together to give you the best ride whether your truck is loaded or unloaded, so you get the adjustable load support of air springs and the comfort and reliability of jounce springs.

  • Will Coil SumoSprings, # CSS-1094F, Raise the Ride Height on a 2013 Dodge Ram 1500 Crew Cab
    The Coil SumoSprings, # CSS-1094F, are designed to fit in the space between coil turns on the springs and would not change the ride height of your 2013 Dodge Ram 1500. We do offer SuperCoils, # SSC-50, that will increase the height by 3/4 inches. If you are looking for more lift than that you will want to look at lift kits. I have included a link to the installation instructions for you.

    You can install suspension enhancement on just the rear of your Ram.

These will also raise the back of the vehicle 3/4 inch. These are designed to replace the rear coils on your truck.

    The SumoSprings Solo Custom Helper Springs, # SSR-307-40 are rated at 1,000 lbs. and the # SSR-307-47 are rated at 1,500 lbs. These are a great products and improvements over the factory components however, because you state "...very close to maxing out my payload capacity so I need to make sure I did the most supportive thing possible..." I do not recommend these because they are not the best for your situation. The Air Lift LoadLifter 5000 Ultimate Air Helper Springs with Internal Jounce...

  • 2020 Ram 1500 Still Squats with Timbrens Installed
    The Timbren Rear Suspension Enhancement System part # TDR1500DQ is a good option for a 2020 Ram 1500. That said, it won't get rid of all squat since the suspension has to reach a threshold before they even engage. If you like, you can get rid of more squat by adding spacers to have them engage sooner, the Timbren Spacer part # TA25722-90P00 for 1/2" or part # A25723-90AH00 for 1". That said, the above can result in a rougher ride so a better option would indeed be stiffer coil springs,...
