Hellcat Suspension Guide: Lowering Springs vs. Coilovers, Sway Bars & Launch

Suspension is where a Hellcat’s massive supercharged output either hooks up or goes up in smoke. Whether you want a better stance, sharper handling, or a harder launch, the right parts make the difference — and the wrong ones bring a harsh ride and wheel hop. This guide helps you pick the right setup and points you to both new parts on Amazon and used/OEM suspension components on eBay Motors.

First, decide your goal

Better stance and mild handling gains: lowering springs on quality dampers are the cheapest, simplest path. They close the fender gap and improve body control without breaking the bank.
Serious, tunable handling: coilovers give you adjustable ride height and (on better units) adjustable damping, so you can set the car up for street or track. Bigger investment, bigger payoff.
Drag and launch: upgraded rear dampers, anti-wheel-hop bushings/control arms, and the right spring rate help the car plant its tires.

Be realistic about how you drive — a track-stiff coilover on a comfy street cruiser gets old fast.

Lowering springs

Springs are a popular first Hellcat suspension mod: affordable, a clean drop, and better body control. Match them to dampers rated for the lower ride height, mind the adaptive-damper setups on SRT cars, stay within a sensible drop, and get an alignment afterward to protect your tires.

Coilovers

Coilovers are the answer when you want to seriously dial in the car:

Choose ride-height and damping adjustment appropriate to your use — street-comfort valving vs. track-firm.
Don’t slam a heavy, powerful car; excessive drop ruins geometry, ride, and traction. Set a sane height and corner-balance if you can.
Budget for an alignment to keep tire wear even.

Traction and launch parts

On a car this powerful, wheel hop and traction are real concerns. Anti-hop bushings, control arms, and matched rear dampers plant the tires on hard launches. Browse the suspension category for these components, and pair them with drag radials from the wheels & tires category for the strip.

How to buy

New springs, coilovers, and traction parts: Amazon Automotive — see suspension parts.
Used or OEM suspension components: eBay Motors, via the search buttons above.

Measure your drop, confirm fitment against your exact car and year, and plan for the alignment — a suspension setup done right transforms how a Hellcat drives and launches for years.

Frequently Asked Questions

What's the difference between lowering springs and coilovers on a Hellcat?

Lowering springs drop the car a fixed amount on your factory or upgraded dampers — cheap, simple, and great for cleaning up the fender gap. Coilovers replace the whole strut/shock assembly with adjustable ride height and, on better units, adjustable damping — far more capable and tunable, but more expensive and firmer. Springs suit a street car chasing looks; coilovers suit anyone who wants to seriously dial in handling. Note that Hellcats with the adaptive (SRT) dampers need setups that account for the electronic shocks.

Will lowering my Hellcat hurt the ride or cause problems?

A modest drop on quality springs matched to good dampers rides fine and improves looks and body control. Going too low steepens geometry, worsens ride quality, and on a heavy, powerful car can hurt traction and cause wear. Stay within a sensible drop, pair springs with dampers rated for the lower ride height, and get an alignment afterward.

What suspension parts help a Hellcat launch harder?

For drag use, the priorities are different from road-course handling. Upgraded rear shocks/dampers, control arms or bushings that reduce wheel hop, and the right rear spring rate help plant the tires on a launch. Combined with drag radials and a proper tune, these are what turn supercharged power into consistent 60-foot times.
