What Are DJM Suspension Lowering Kits and How Do They Work
DJM Suspension is a company that manufactures suspension components designed to lower vehicles. A lowering kit is a collection of parts that work together to reduce the ride height of a car or truck, making it sit closer to the ground than it does from the factory. These kits have been used in the automotive customization industry since the 1980s and remain popular among car enthusiasts who want to modify their vehicles' appearance and handling characteristics.

Lowering kits typically include replacement springs, shocks or struts, and sometimes additional components like control arm hardware or bushings. The springs in a lowering kit are stiffer and shorter than original equipment manufacturer (OEM) springs. When installed, they compress the suspension system to a predetermined height, reducing the overall clearance between the vehicle's body and the wheels. This creates the distinctive lowered appearance that many vehicle owners seek.
The shock absorbers or struts included in DJM kits are specifically valved to work with the lowering springs. Standard shocks are designed for OEM spring rates and would not function correctly with stiffer lowering springs. By pairing matched components together, DJM kits maintain proper suspension geometry and ride quality. The relationship between spring rate, shock valving, and vehicle weight determines how much the suspension will compress.
Different DJM kits are designed for different vehicles and desired drop heights. A typical lowering kit might reduce ride height by 1.5 to 3 inches, though some kits offer more aggressive drops. The amount of lowering affects how the suspension performs, how the vehicle handles, and what other modifications may be needed. Understanding these relationships helps vehicle owners make informed decisions about which kit suits their needs.
Practical Takeaway: Before purchasing any lowering kit, research the specific drop height and component specifications for your vehicle's year, make, and model. Different vehicles require different kits, and using the wrong components can damage your vehicle or create safety problems.
Types of DJM Lowering Kits Available
DJM Suspension manufactures several categories of lowering kits to accommodate different vehicle platforms and performance goals. Understanding the distinctions between kit types helps vehicle owners select products matched to their specific vehicles and preferences.

Coilover kits represent one major category. These systems combine a spring and shock absorber into a single integrated unit. Coilovers allow for adjustable ride height, meaning the owner can lower or raise the vehicle by adjusting the position of the spring perch on the shock body. This adjustability appeals to owners who want to fine-tune their vehicle's stance or who may need to raise the vehicle occasionally for practicality. DJM coilover kits typically offer adjustability ranges of several inches in either direction from a baseline setting.
Spring and shock packages represent another common DJM offering. These kits pair lowering springs with matched shocks or struts but keep them as separate components. Once installed, the ride height is fixed at the design height for that kit. Spring and shock packages generally cost less than coilover systems and are often simpler to install, making them popular among owners with moderate budgets who want straightforward modifications.
Height-specific kits are another option DJM provides. Some customers want modest lowering of 1 to 1.5 inches for a subtle aesthetic change, while others pursue more aggressive 2 to 3-inch drops for a dramatic stance. DJM manufactures kits calibrated for different target heights, and each height specification involves different spring rates and shock valving. A 1-inch lowering kit uses different components than a 3-inch lowering kit, even for the same vehicle model.
Application-specific variations address the needs of different vehicle segments. Kits for trucks differ significantly from kits for sedans because trucks have different suspension designs, weight distributions, and intended uses. DJM produces separate product lines optimized for each vehicle type, recognizing that front-wheel-drive sedans, rear-wheel-drive sports cars, and pickup trucks require different engineering approaches.
Practical Takeaway: Research whether a coilover or spring-and-shock kit better matches your needs. Consider your budget, how permanent you want the modification to be, and whether you might need height adjustability in the future.
Installation Process and Technical Considerations
Installing a DJM lowering kit involves removing the vehicle's original suspension components and replacing them with kit components. While the basic process is conceptually straightforward, the actual work requires mechanical skill, proper tools, and often a substantial time commitment. Most installations require the vehicle to be safely lifted on jack stands and the wheels removed. Professional installation at a shop typically takes 4 to 8 hours depending on vehicle complexity and technician experience.

The installation sequence generally follows this order: remove the wheels, unbolt the original shock absorbers or struts, remove the original springs, install new springs on the shock bodies or replace complete strut assemblies, install sway bar links or end links if included in the kit, reconnect everything, and reinstall the wheels. Some vehicles have additional components like bump stops that must be checked or adjusted. The complexity increases if the vehicle has integrated spring seats or complex strut designs that require special tools.
Proper alignment becomes critical after any suspension modification. Lowering a vehicle changes suspension angles including camber (the tilt of the wheel relative to vertical), caster (the forward or backward angle of the steering axis), and toe (whether the wheel points inward or outward). A vehicle that was properly aligned with factory suspension may have poor alignment after lowering. Driving on misaligned wheels causes uneven tire wear, pulling to one side, and reduced handling precision. Most shops include or recommend a wheel alignment after lowering kit installation, and this service typically costs between $150 and $300.
Potential complications can arise during installation. Corroded or stuck fasteners may require additional time and tools to remove. Some vehicle models have design features that make suspension work more difficult, such as limited access or components that require special removal sequences. Pre-purchase research on forum discussions about your specific vehicle can reveal common installation challenges. If you plan to do the work yourself, reviewing YouTube videos of others installing the same kit on the same vehicle model provides valuable insight into what to expect.
Practical Takeaway: Budget for professional installation and alignment work unless you have significant suspension repair experience and proper tools. The cost of installation and alignment typically ranges from $500 to $1,200, which should factor into your overall investment decision.
Effects on Vehicle Handling and Ride Quality
Lowering a vehicle affects how it handles and how it feels to drive. The primary handling benefit comes from lowering the center of gravity. When a vehicle's weight is positioned lower, physics causes less body roll during cornering. Body roll is the tilting motion vehicles experience when turning; reducing it improves cornering grip and makes the vehicle feel more stable and responsive during directional changes. Many owners report noticeable improvements in handling sharpness and cornering confidence after installing a quality lowering kit.

The stiffer springs in lowering kits also contribute to handling improvements. Stiffer springs reduce suspension motion and vertical bounce, keeping the tires more consistently planted on the road surface. This provides better grip and more direct steering response. However, this same stiffness creates a tradeoff: the ride becomes firmer and more responsive to road irregularities. Bumps that barely registered with soft factory springs become more noticeable with lowering kit springs. Roads with significant cracking, potholes, or rough pavement surfaces become less comfortable to drive on.
The shock absorbers included in DJM kits are specifically tuned to match their paired springs. This matching prevents excessive bouncing and ensures the suspension settles quickly after bumps. A mismatched shock and spring combination would result in poor handling and an uncomfortable driving experience, which is why using kit-specific components matters. The shocks control the rate at which the springs compress and extend, maintaining the balance between handling performance and ride comfort.
Ride quality varies based on the specific kit, the vehicle, road conditions, and driver preferences. Some owners find the firmer ride from a 1.5-inch drop barely noticeable, while others find it objectionable. More aggressive drops of 3 inches or more typically produce noticeably stiffer rides. Before purchasing, research owner reviews of the specific kit for your vehicle to understand realistic expectations about ride quality. Many online forums contain detailed owner feedback about suspension modifications.
