AAL - Add-A-Leaf, refers to a suspension kit that puts and additional leaf into a spring pack, most often used to either raise the height of a vehicle and/or raise the load capacity. AATS - Ambient Air Temperature Sensor. ABS - Anti-lock Braking System, designed to control braking and prevent skidding in emergency stopping situations. All 2nd Gen Rams have rear wheel ABS as standard equipment. 4 wheel ABS was an option on 1500s and standard on 2000-up 3500 models and 2001-up 2500/3500 models. A/C - Abbreviation for air conditioning. ASD relay - Auto Shut Down relay. A/T - in reference to tires this means All Terrain, a tread pattern for general use including off-road. Also, an abbreviation for automatic transmission. BFG - B.F. Goodrich tire company. Bolt-on - a product designed to be easily installed without fabrication or modification of existing structures, often using existing hardware and/or mountings. A simple replacement or add-on. Box - slang for cargo bed. CAD - Center Axle Disconnect, system used to connect/disconnect the front axle on Dodge trucks from transfer case output. CAI - Cold Air Intake, a device designed to allow cooler intake air to be used rather than the warm underhood air, resulting in better performance. Cat - short for catalytic converter. Cat-back - exhaust system comprised of components from the exit of the catalytic converter to the exhaust tip, usually including the muffler. CC - Club Cab CEL - Check Engine Light, the dashboard indicator that there is a trouble code stored in the PCM. Closed Loop - refers to a type of EFI control design, this is a system wherein all engine adjustments (timing, ignition, spark, etc.) are made in response to the monitoring of sensors (TPS, CPS, 02, MAP, etc.) whose feedback are fed to the ECM and used to calculate various performance parameters. This system is more efficient as it reads actual performance data on-the-fly and can adjust for things like engine load, speed, fuel demand, etc. 1997 and later Dodge RAMs use this type of system (See also Open Loop). Cowl induction - a type of hood design that allows cool air to be drawn into the engine compartment/intake from the base of the windshield. Most often this is an aesthetic design and is non-operative. CMP sensor - Camshaft Position Sensor, used by the ECM to determine the position of the camshaft for adjusting various parameters like ignition timing and cylinder firing sequence. CPS or CKP sensor - Crankshaft Position Sensor, relays crankshaft position to the ECM. DD - Daily Driver, refers to a vehicle that is driven daily or almost daily, usually not a weekend project vehicle or dragstrip vehicle. DIY - Do It Yourself. DRW - Dual Rear Wheels, also referred to as a Dualie. ECM, ECU or PCM - Electronic Control Module; Electronic Control Unit; Powertrain Control Module; the main vehicle computer that controls all engine systems. ECT sensor - Engine Coolant Temperature sensor, relays engine temperature info to the ECM. EFI - Electronic Fuel Injection. FIPK - Fuel Injection Performance Kit, primarily sold by K&N, this is an air intake system designed to increase performance. Fuel rail - metal tubing that supplies fuel to the individual injectors. Headers - type of exhaust made up of individual tubes for each cylinder that provides better performance. HID - High Intensity Discharge, a type of lightbulb. IAC - Idle or Intake Air Control, a solenoid mounted on the throttle body used to regulate incoming air at idle. IAT sensor - Intake Air Temperature sensor, relays intake air temperature readings to the ECM. ICE - Internal Combustion Engine. Kegger - refers to the intake manifold design of some Chrysler V8 engines, so called because it resembles a beer keg. Leveling Kit - usually a simple bolt-on designed to level the front of a truck with the rear. LB or LWB - Long Bed or Long Wheel Base, refers to those truck models with the longer cargo bed. Limited Slip - type of differential that provides equal power to both wheels on an axle regardless of traction by means of a clutch pack or other means (see Locker and Posi). Standard equipment on some RAM 4X4 models. Locker - a differential device that locks axle output to provide power to both wheels regardless of traction. Similar to a posi or limited slip in performance, but uses other mechanical means. Usable only in off-road or limited traction situations. Longtube - as opposed to shorttube, refers to a type of exhaust header that is longer in length. MAF sensor - Mass Air Flow sensor, determines the amount of intake airflow and relays it to the ECM (not used). MAP sensor - Manifold Absolute Pressure sensor relays info regarding intake air pressure/vacuum to the ECM. M/T - in reference to tires this means Mud Terrain, an aggressive tread pattern designed for mud use. Can also refer to the Mickey Thompson tire brand. Nerf bars - bolt-on accessory bars used to protect against body damage. Most often side bars, but can also be front end mounted. NV3500 - A five speed manual transmission used on V6 and some light-duty V8 powered vehicles. NV4500 - A five speed manual transmission used on some V8 and V10/diesel powered vehicles. 02 Sensor or Oxygen Sensor - a device that monitors the amount of oxygen in an engine's exhaust to determine the degree of combustion and its efficiency in order to cause the PCM to adjust various operation parameters accordingly. Used in Closed Loop EFI systems. Single 02 sensor systems monitor combustion efficiency only. Dual 02 sensor systems monitor both combustion and catalytic converter efficiency. Depending on the design of the exhaust system, there can be either 1, 2 or 4 (CA only) 02 sensors on a vehicle. OBDI or OBDII - On Board Diagnostics; a diagnostic tool for reading trouble codes stored in the ECM. Type is determined by model year of vehicle and EFI system design. OD - Over Drive, designates a transmission with a gear that provides a final drive ratio less than 1:1. Off Road Edition - an option offered on RAM 1500 models consisting of 2" higher suspension lift, special alloy wheels, different steering ratio, front tow hooks, beefed-up front differential, HD charging and cooling upgrades, and insignia. Open Loop - refers to a type of EFI control design, this is a simple system wherein performance is determined by just a few monitored sensors and controlled by preset parameters stored in the ECM (called maps). Unlike a Closed Loop system, it can not adjust performance on-the-fly as these systems do not include an 02 sensor to monitor exhaust gasses. 1996 and earlier Dodge RAMs use this type of system. (See also Closed Loop). PCV valve - Positive Crankcase Vent valve. Plenum - refers to the lower intake manifold plate, where the gasket between it and the intake manifold itself often fails allowing oil and engine vacuum to leak past. Common problem on Chrysler Magnum V8 engines. Posi - short for positive traction, catchall phrase that refers to any type of differential that sends power to both wheels regardless of traction (see Locker or Limited Slip). QC - Quad Cab. RAC - Round Air Cleaner (see also 14X3). Rad - short for radiator. Roll pan - replacement panel for rear bumper that gives a smooth, contoured look to vehicle rear. SB or SWB - Short Bed or Short Wheel Base, refers to those truck models with the shorter cargo bed. Shaker - a hood scoop design that allows cool air to be brought into the intake stream from outside the engine compartment. So called because it is usually mounted to the engine and sticks out through a hole in the hood allowing it to "shake" with engine vibration or torque. SLT Laramie Edition - a mid-level RAM trim option, also referred to as just Laramie or SLT. SLT+ Edition - highest RAM trim option that includes leather seating. Sport Edition - limited edition RAM model easily identified by its distinctive color-matched front and rear bumpers. ST - standard RAM trim level. TB - Throttle Body, a device that regulates the airflow into the engine. TB spacer - a plate used to distance the throttle body further from the intake manifold, supposedly resulting in performance gains. Sometimes also used in conjunction with a 14x3 air cleaner assembly for clearance purposes. Throw codes - slang for the storing of codes in the ECM relative to monitored system malfunctions. TPS - Throttle Position Sensor. Tranny - slang for transmission. VB - Valve Body, section inside the transmission responsible for hydraulic actuation of shifting circuits.

Good Job! YOu should post this in the FAQ section.

[Silver_Dodge]

I made this a sticky instead since it isn't really a DIY. I'm going to leave it open for people to suggest other acronyms, and either Miami or any mod can update the master list in post #1.

[Silver_Dodge]

2 that I can think of that get asked about a lot are:

kegger
CAD

[hirschy]

I heard this awhile back

dizzy - distributor

Isn't Laramie higher then the slt?

I was gonna say keggar but silver beat me to it.

[Silver_Dodge]

Ya, Laramie was the highest trim level. It went ST, SLT, SLT Laramie.

[Cereal Killer]

FIPK - Fuel injection performance kit

Also

MAP sensor

I'm curious to know what Laramie adds to the package? My build sheet says only SLT Plus, but I have every option that was available at the time, including leather interior, heated mirrors, heated seats, motorized driver/passenger seats, steering wheel radio controls, overhead computer, camper and towing packages. I can't think of anything else that could be added by the Laramie package.

[PurplDodge]

All SLTs are SLT Laramies, but they just called them SLTs. It went ST, SLT Laramie, SLT+ (Which is what you have, Miami). I think the Laramie designation comes from the newer Rams which are ST, SLT, Sport, and Laramie.

That's what I thought and why I originally said that SLT was the highest trim level offered.
