2014-2023 Dodge Ram Front Coils


Regular price $360.00

Our soft-rate coil springs are the perfect blend of a soft ride, high performance, and great control. 


  • Normal 4WD 2500/3500 trucks, and also fit most 2014+ 2-Wheel Drive 2500/3500 trucks with the straight front axle.


  • Sold in Pairs
  • If you're not purchasing our shocks with these coils, please contact us to make sure your preferred shocks will function properly. Even aftermarket shocks by application for a leveling kit with stock coils, will not work properly, as they are much too short extended and the damping rates are way off.
  • The 3500 Rams are 1/2" taller than the 2500 from the factory, which is the reason for the height difference.
  • Each 5160 alloy spring is fully CNC computer formed and tested, using the most high-tech manufacturing processes.
  • 26-30% softer than the ultra-stiff OEM coils, while designed to still use factory compression/bump travel. Bump drops are not needed.
  • Radius Arm drops are not required because these coils are designed around the OEM bump travel constraints.
  • Proven Linear Rate design to prevent inconsistent feel throughout the range of motion.

Starting in 2013 on the radius arm platform, Ram decided to design the front coil spring mounts at an angle. This presents some issues with the coils design, as the coil has a very hard time standing straight without a massive bend in the coil, when loaded.

This might be why the OEM coils are so stiff. Stiff coils will bend less. Regardless, with some tricky engineering we were able to combat the angled seats, and design a coil which stands very straight after install.

2WD - We make a 2 Wheel Drive specific front Trackbar, the shocks needed for these coils will fit the 2 Wheel Drive also. It is a good idea to email us pictures of your 2 Wheel Drive suspension to verify fit, pre-purchase.

Good product

Coil spring and as what I was looking for great ride and leveled the truck easy to put in

Great lift

Love it, looks great fit great, easy install if you have the tools. I went with the 2.75 for my truck because I have the ranch hand bumper with the 18,000 pound winch, sits 1 inch lower than the back. Looks level to the eye. Went and had it alighned after it was 1 degree off basically all the way around. So your truck will need to be realigned after installation

2" level springs

Phenomenal, why anyone uses spacers is beyond me, well worth the minimal price difference and included shocks

They work great.

Better then stock

They are not as soft as I was hoping. I’m not sure if that’s because I put them on a 2500 with a 5.7L hemi and without the extra weight of the Diesel engine I may just not be feeling the full affect/smoothness of these coils or what. Compared to stock coils with lift spacers they do feel a bit better but far from feeling like a 1500. Bumps in road are still rough.
