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.

Chevrolet Silverado 2500

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

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.

The SSC-30 is for 2WD models. For a 2WD version, you have two options, either the SSC-30 for 3,395 pound capacity or SSC-31 for a 5,000 pound capacity. For a 4WD version, the part is SSC-33 with a 3,750 pound capacity.

-- Etrailer Expert Patrick B - 10/2/2013

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 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

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!

  • Recommended SuperCoils For 2021 Ram 1500 Sagging 3" When Towing Trailer
    Personally I would go ahead and install the Timbren suspension enhancement since it is a pretty easy install on your 2021 Ram 1500, and see if it provides enough support for your needs. If you find it does not provide the support you are looking for I would add the SuperCoils Custom Suspension Coils - Rear Axle # SSC-51 which will provide an additional 2480lbs of support to your suspension. I included a video of the # SSC-51 for you to take a look at.

  • Best Suspension Enhancement For a 2019 Ram 1500 Classic Pulling a 5,300LB Travel Trailer
    The SuperCoils Custom Suspension Coils # SSC-51 can be used with another suspension system like the Timbren Rear Suspension Enhancement System # TDR1500DQ. The Timbren will not work your 2019 Ram 1500 if it is a regular cab or has factory air suspension. Since it sounds like you only need the suspension enhancement when you are towing your travel trailer, I recommend using a Equal-i-zer Weight Distribution System # EQ37100ET. With the Equal-i-zer you will be able to level your Ram and...

  • How to Reduce Bouncing on a 2017 Ram 1500 with Weight Distribution System
    The bouncing feeling you are describing is not caused by improper installation of your weight distribution system. This is actually an adverse effect of the system. The ride on your 2017 Ram 1500 has become more stiff in the rear as a result of the weight distribution system working to distribute the tongue weight of the trailer. Because the ride has become stiffer, you are going to experience more bouncing. The only way to help with the bouncy ride would be release tension on the spring...

    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.

    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.
