The Ultimate Guide to Hellcat Suspension Parts

Dodge Hellcat owners know the thrill of 707+ horsepower. But raw power is only half the story. Without a properly tuned suspension, that massive torque can turn your drive into a white-knuckle struggle for traction. Upgrading your Hellcat’s suspension isn’t just about lowering the car for looks – it’s about transforming how it accelerates, corners, and stops. This guide walks through the essential suspension parts, what each does, and how to choose the right setup for your driving style.

Why Upgrade Hellcat Suspension?

Stock suspension limitations

Factory Hellcats come with a capable, compliant suspension tuned for daily driving and occasional spirited runs. However, the stock components prioritize ride comfort and cost over maximum performance. Soft springs, limited damping adjustability, and rubber bushings all allow excessive body roll, squat under acceleration, and dive during braking. At the track or on a twisty road, these traits become bottlenecks.

Benefits of aftermarket suspension

Better control: Aftermarket suspension parts reduce unwanted movement, keeping the tires planted for improved traction and cornering confidence. Consistency: Higher-quality shocks and springs resist fade during sustained hard driving. Adjustability: Many aftermarket parts let you dial in ride height, damping, and stiffness to match your use – from daily commuting to autocross or drag racing. Weight reduction: Some components, like aluminum control arms, cut unsprung weight for sharper response.

Key Hellcat Suspension Parts

Coilovers vs. Shocks and Springs

Coilovers are the most popular upgrade for Hellcats seeking performance and adjustability. A coilover combines a shock and spring into a single unit with adjustable ride height and often damping. They offer the widest range of tuning – lowering 1–2 inches while maintaining proper geometry. High-quality coilovers from brands like KW, Ohlins, or JRZ can transform handling without sacrificing daily comfort.

Shocks and springs, sold separately, are a simpler path. Upgraded lowering springs (e.g., Eibach, BMR) drop the ride height and increase spring rate, while better shocks (e.g., Bilstein, Viking) control the motion. This setup is less expensive than coilovers but offers limited adjustability. Choose this if you want a fixed performance upgrade without the complexity of coilover tuning.

Sway Bars (Front and Rear)

Sway bars, also called anti-roll bars, link the left and right wheels to reduce body roll in corners. A thicker front sway bar reduces understeer, while a thicker rear bar can induce rotation for sharper turn-in. Most Hellcat owners upgrade both. Adjustable sway bars let you fine-tune balance. BMR and Hotchkis make popular Hellcompatiblesets.

Control Arms and Bushings

Factory control arms use rubber bushings that flex under load, introducing slop and inconsistent geometry. Aftermarket control arms – usually with polyurethane or spherical bearings – eliminate this play for precise wheel control. Front upper control arms (UCA) are especially critical to correct camber after lowering. Brands like SPC, Teraflex, or Core4x4 offer adjustable UCAs for proper alignment.

Sway Bar End Links

End links connect the sway bar to the control arm. Upgrading to adjustable, heavy-duty end links (e.g., BMR, Megan Racing) removes slop and allows proper preload setting. This is a relatively cheap but noticeable improvement.

Strut Braces and Chassis Bracing

A strut tower brace ties the front shock towers together, reducing chassis flex and improving steering response. For the Hellcat, a front brace is common. Some also add a rear brace or subframe connectors (like those from BMR or Steeda) to stiffen the unibody under hard acceleration.

Lowering Springs and Adjustable Ride Height

If you want a lower stance without full coilovers, high-quality lowering springs from Eibach, H&R, or Vogtland drop the car 1–1.5 inches. Pair them with performance shocks. Adjustable ride height is only possible with coilovers or air suspension. Air suspension offers both low height and comfort but adds complexity and weight.

Choosing the Right Suspension Setup

Street Driving vs. Track Use

For a daily driver that sees occasional backroads, a mild setup with linear springs and quality shocks is best. Coilovers on a soft damping setting work well. For heavy track use – autocross, road courses, or drag racing – you want aggressive spring rates, adjustable damping, and stiffer bushings. Drag racing setups often emphasize anti-squat geometry and rear traction, so consider rear lower control arms and adjustable toe links.

Adjustability and Ride Quality

More adjustability means more setup time but better eventual tuning. Coilovers with separate compression and rebound adjustments allow fine-tuning for traction and comfort. If you rarely adjust, a non-adjustable shock and spring combo might suffice. Ride quality depends largely on spring rate and damping. Polyurethane bushings transmit more vibration than rubber or spherical bearings. For street use, choose softer durometer poly or rubber.

Budget Considerations

Suspension parts range from a few hundred dollars for end links to several thousand for top-tier coilovers. A starter package might include lowering springs ($200-400), shocks ($600-800), front sway bar ($200-350), and adjustable end links ($100-200). A full coilover set can be $1,500-$3,000. Control arms add $400-800. Prioritize based on your biggest complaint: body roll? Get sway bars. Too much squat/dive? Shocks and springs. Imprecise steering? Control arms and bushings.

Installation Tips and Considerations

Professional Installation Recommended

Suspension components involve spring compressors, specialized tools, and precise torque specs. Improper installation can be dangerous. Unless you have experience, hire a shop that works on performance cars. Alignment is mandatory after any suspension change – skip it and you’ll wear tires unevenly and reduce handling.

Alignment After Suspension Work

After installing new parts, especially control arms or lowering springs, get a professional alignment. Adjustable components allow you to set camber, caster, and toe for your use. Street alignment: minimal negative camber for even tire wear. Track alignment: more negative camber for cornering grip. For drag, aim for zero rear toe and a slight positive caster if possible.

Final Recommendation

For most Hellcat owners looking for real-world improvement without breaking the bank, start with a quality set of adjustable coilovers and a front sway bar. This combination directly addresses the main handling complaints – body roll, brake dive, and squat – while allowing you to dial in ride height and damping. Add adjustable end links and a rear sway bar if you want further fine-tuning. For those focused on drag racing, prioritize rear control arms and adjustable shocks to control wheel hop and improve launch. Avoid cheap components; a $1,500 coilover set from a reputable brand will outperform and outlast a low-cost hit. Invest in professional installation and alignment – it ensures your Hellcat’s suspension works as intended, making every drive more controllable and enjoyable.
