Bilstein OE Replacement Air Springs

Bilstein OE replacement air springs are designed to replace worn original suspension components. Over the years, air springs can begin to leak, and when they do they will no longer be able to hold the air pressure required to keep the vehicle riding smoothly and at a level ride height. Each Bilstein OE replacement air spring is designed to connect directly into the original connectors on your vehicle, ensuring modification-free installation and restoration of the original feel of the vehicle. Features include: * OEM-quality standards * Proven Bilstein gas pressure technology on springs with integral shocks/struts * Responds to street and vehicle conditions in milliseconds for instant adaptivity * Provides excellent comfort and perfect driving characteristics * Axial bellows provide sensitive spring behavior with a comparably low rolling radius--ensures optimum functionality even in confined working chambers

MSD Atomic EFI Throttle Body Systems

These MSD Atomic EFI fuel injection systems are the perfect choice for anyone planning on converting from carburetor to fuel injection. They include a throttle body, power module (with wideband oxygen sensor), and handheld controller. The throttle body features an integral ECU built on the side, incorporating the TPS, MAP, IAT, and fuel pressure sensors, all in one location. Fuel delivery is provided by four precision 80 psi injectors featuring a stainless steel ball and seat metering method for maximum internal sealing. They also use internal fuel rails, providing a sleek appearance and removing fitting connections where leaks can develop. Atop the Atomic EFIs are annular booster rings that deliver superior atomization of the best fuel mixture, ensuring the best possible fuel delivery. Best of all, the MSD Atomic EFI fuel injection systems bolt directly to any standard square bore carbureted intake manifold and accept the same linkage as most carburetors. The 1.75 in. diameter throttle inlets ride in precision roller bearings for a smooth pedal transition. The Atomic EFIs' unique TPS is a self-calibrating, non-contact sensor, which means that you don't have to worry about configuring it during setup. The included power module is a remote mounted piece that handles all of the high-current loads. MSD's CAN-Bus technology allows for a single, clean connection between these units and the throttle body mounted ECU. Control all of the MSD Atomic EFI fuel injection systems' functions with the hand-held device. Initial setup takes about five minutes, and you'll answer six questions about your specific engine. After the initial setup is complete, the device can provide you with engine data to help you keep your engine working properly. They also feature a removable micro-SD card to record and store data so that you can see what's going on with your engine.

QA1 Rear MOD Coilover Conversion Systems

QA1 MOD Series coilover conversion systems put the ability to re-valve your shocks—on your car—into the palm of your hand. These innovative shocks feature QuickTune Technology, an industry-first that provides the ability to adapt to any track, any conditions, any time. The technology consists of interchangeable, dry modular valve pack assemblies, that can be thought of as dozens of finely tuned shocks you can hold in the palm of your hand. They define the valving curve of the shocks, and can be changed without interrupting the oil pathways. Simply unscrew from the shock, bolt-in another one with a new pre-determined valving range—and you're ready to go. There's no mess, no contamination, no air intrusion, and no downtime waiting on someone to re-valve your shocks. Ideal for Circle Track and Street/Strip applications, the shocks are available in a variety of extended and collapsed length models to best fit your vehicle. You get everything you need with these QA1 Rear MOD systems, from shocks to nuts and bolts, complete installation instructions, and even decals! Additional benefits and features of QA1 MOD Series shocks: * All new design delivers force, control, and unmatched tenability * Hard anodized aluminum bodies with PTFE—durable, non-galling surface * Double-adjustable shocks with low-speed bleed adjustments * Large solid piston (with blow-off valve)—improved driver feel and control with up to 1,600 lb. force * High-speed valving adjustment (coarse adjustment)—relates to shock operation during impact events, like hitting a pothole or curb * 24 clicks/settings—wider range of adjustment than comparable shocks * Indexable base eyelet—multiple mounting position to optimize knob access and provide more mounting flexibility * Low-speed valving (fine-tune adjustments)—adjusts ride quality and weight transfer on corner entry/exit; more bleed for softer feel and less bleed for stiffer feel * Piggyback or remote canister options * Unique spring adjuster nut and tool * Thrust bearings included * Superior thermal performance, as oil is in constant contact with outer body * One base shock can be upgraded over time to keep up with increased performance levels of your vehicle

Medium compression and rebound valve packs come standard; soft or firm compression and rebound valve packs are also available. Once the desired valving is in place, the unique double-adjustable design (with adjustable low-speed bleed) allows for fully independent control over the compression and rebound characteristics. With all these adjustability options, MOD Series shocks achieve an expansive force curve capability and an unprecedented level of tunability. The shocks also feature mounting adjustability to accommodate a variety of vehicles and mounting configurations. The nitrogen-charged canister is available in a piggyback or remote configuration for ease of installation in tight areas, and the base eyelet is indexable, so you can unbolt and reattach it at the angle you need for the best shock and canister placement. Like all QA1 shocks, MOD Series coilovers are 100 percent dyno-tested and serialized. Order the kit recommended for your vehicle.
