Eibach Lowering Springs
Eibach's lowering springs for cars come in two street lines: Pro-Kit, a 1.0-1.5" drop for a daily-driver stance, and Sportline, a firmer 1.4-2.0" drop for a more aggressive look and tighter handling. Both reuse factory shocks and mounting hardware, carry a Five-Year Warranty, and are sold application-specific by vehicle.
Eibach publishes drop ranges, part numbers, and pricing per application on its own site. This page compiles those figures from Eibach's product pages and owner reports, not from our own installs.

Pro-Kit vs Sportline: which Eibach line fits your car
| Series | Typical drop | Character | Best for |
|---|---|---|---|
| Pro-Kit | 1.0" - 1.5" | Progressive rate tuned for daily comfort and tighter body control | Daily drivers, mild track days, drivers who want a visual drop without giving up ride quality |
| Sportline | 1.4" - 2.0" | Firmer progressive rate, more aggressive stance | Weekend and show cars, drivers who accept a stiffer ride for a lower look and sharper turn-in |
These ranges come from Eibach's own Pro-Kit and Sportline product pages; actual drop on a given car varies by application, factory ride height, and whether that trim has an adaptive-damper system like MagneRide. Both lines carry Eibach's Five-Year Warranty and are engineered to work with the factory shocks and strut mounts, so there's no separate damper purchase required to run either kit.
Who Pro-Kit and Sportline are for
Pick Pro-Kit if the goal is a factory-plus-one stance: lower, firmer, and more composed through corners, but still comfortable enough for a daily commute. Pick Sportline if the priority is the lowest factory-damper-compatible stance Eibach publishes for that platform, and a stiffer ride is an acceptable trade-off for the look. Neither kit changes ride height after installation the way coilovers do - the drop is fixed by the spring, so getting the application-specific part number right before ordering matters more than with an adjustable setup.
Eibach vs H&R and D2 Racing
Eibach is one of several spring makers selling application-specific kits for the same platforms. H&R is another OEM-grade German manufacturer with its own drop and spring-rate specs worth cross-shopping before you buy. D2 Racing sells lower-priced kits aimed at budget builds, typically pitched at a more aggressive drop and firmer rate than either Eibach line. Compare published drop, spring rate, and warranty on each brand's page rather than price alone - a cheaper spring that sags out of its rate within a year of road use ends up costing more in ride height and alignment work.
Installation and ride-height notes
Lowering springs are a fixed-rate part: there's no ride-height adjustment after the spring goes in, unlike a coilover's threaded sleeve. Installation means compressing the factory spring off the strut or shock with a coil spring compressor, swapping in the Eibach spring, and reassembling - see the lowering springs installation and cost breakdown for typical shop time and pricing. Budget for an alignment afterward, since camber and ride height both shift once the car settles on the new springs.
Fitment: what Eibach actually lists per vehicle
Eibach publishes Pro-Kit and Sportline part numbers per vehicle rather than a universal kit, so drop, price, and whether MagneRide or other adaptive dampers are excluded all depend on the exact year and trim. The rows below come straight from Eibach's own product pages for two of the most-searched applications; for other platforms, check the Mustang and Charger/Challenger/300 pages, or browse lowering springs by car for the full list.
FAQ
What's the difference between Eibach Pro-Kit and Sportline lowering springs?
Pro-Kit drops a car about 1.0-1.5 inches with a progressive rate tuned for daily comfort; Sportline drops it further, about 1.4-2.0 inches, with a firmer rate for a more aggressive stance and stiffer ride. Both reuse the factory shocks and carry Eibach's Five-Year Warranty.
How much do Eibach lowering springs cost?
Application-specific kits such as the Mustang GT Pro-Kit (35145.140) and the Dodge Challenger/Chrysler 300 Pro-Kit (2895.140) list at $395 for a set of four springs at the time of writing, per Eibach's own product pages. Check the current price at the retailer linked above since it changes.
Do Eibach lowering springs need new shocks or struts?
No. Eibach's Pro-Kit and Sportline are designed to work with the factory shocks, struts, and mounting hardware on the applications they list - no damper swap is required.
Are Eibach Pro-Kit springs comfortable enough to daily drive?
Eibach markets Pro-Kit as the daily-driver-friendly line, with a progressive spring rate meant to improve handling and stance without the stiffer ride of Sportline. Owners who want the firmest drop Eibach publishes for a platform typically step up to Sportline instead.
Will Eibach lowering springs fit my car with MagneRide or adaptive dampers?
Not always. Eibach's own fitment listings for several Mustang and Dodge applications explicitly exclude cars with MagneRide or self-leveling suspension - check the exact trim and options on Eibach's application search before ordering.
What's included in an Eibach Pro-Kit or Sportline box?
Each kit is a set of four springs (two front, two rear) sized for the specific vehicle application - Eibach doesn't bundle shocks, struts, or installation hardware with either line.
