  • NOW you can stylishly hide the LS engine coil packs. Unlike the plastic or fiberglass versions, these covers are machined from 6063-T6 aluminum and can be ordered in black or grey powdercoated finishes; they're also available unfinished so you can customize them to match your vehicle.

The covers fit GM LS engines utilizing existing coil bracket mounting points, and are ideal for LS crate motors. (Unless a cutout is fabricated or aftermarket alternator and brackets are used, they will not clear factory high mount alternators, like those found on Corvettes.)

These ignition coil covers can be used with relocated coil packs for a lower profile appearance, and are best suited for aftermarket serpentine pulley systems. Additionally, they're available with or without the oil fill hole.

  • This transmission controller is designed for situations where a standalone transmission controller cannot control the transmission directly.

This all-in-one solution that will allow the 6L80E or 6L90E just transmission and factory controller to be installed in any vehicle with any engine combination and maintain a fully functional transmission. This can also be programmed to activate 2 additional calibrations, each including shift tables and torque converter lockup table. It has been used in many applications and engine combinations, such as Cummin 2.8L, 4BT Diesels, Gen 1 , 2 and 3 GM engines. Whether they are carbureted or Fuel Injected, this system will allow you to use the GM 6 Speeds in practically any vehicle. Comes with a complete harness and the necessary software to program the module.

Also compatible with the GM 6L45/50, 6L80/90, 6T30/40/45 and 6T70/75E.

  • Lokar drive-by-wire electronic throttle control pedal assemblies are the first programmable electronic throttle pedals for the automotive aftermarket. They feature a programmable, non-contact, solid-state Hall effect sensor for most GM, Ford, and Mopar applications. The pedal assemblies use a splined arm for versatile mounting with all-metal, aluminum, and stainless steel construction. The sensor is programmed on the pedal to optimize electrical output for quicker throttle response, producing no pedal lag and three times the performance of OEM pedals. Lokar drive-by-wire electronic throttle control pedal assemblies are available in your choice of a brushed or black anodized finish to complement the interior of your vehicle. A control module and harness are required for operation; they are sold separately.

  • Direct plug-in cruise control for GM LS drive-by-wire engines, the CRC Series plugs directly into your OEM LS throttle pedal for not only simple installation, but reliable operation and connectivity. Self-learning calibration makes this system a snap to use, with no DIP switches or charts to follow!
The CRC-1000 obtains its information from the included diagnostic connector and throttle pedal connections, allowing an extremely simple installation for drive-by-wire GM CAN bus applications. The CRC-1000 is ideal for applications using all matched OEM drivetrain control components.

Fits GM LS (V8) applications from 2006 - current (except Pontiac GTO & G8 applications).

GM bolt-on turn signal stalk is supplied (Handle 3). Inputs for power, ground, and a connection to your existing brake light switch are all that is required. Additionally, an output is provided for a cruise-on indicator.

  • Finally, the missing link between your muscle car’s original, cable-driven speedometer and swapped-in electronic transmission!
Measuring a compact 5” x 4.1” x 2.15”, the new Electronic Cable Drive, allows the use of a mechanical-cable speedometer to be used in conjunction with a modern drivetrain which provides only an electronic output. Supplied with provision for GM Thread-On or Clip-On style cable (cable is 36” in length).
Quiet operation from the powerful motor allows the user to place the module inside the cabin. The case is waterproofed, allowing it to alternatively be mounted under the hood, or even inside a fenderwell. Simple calibration with a remotely-mounted switch means there are no DIP-switches to hassle with; access to ECD module is not required! Industry-standard ‘measured-mile’ calibration as well as speed adjustment while driving, based on a GPS or other known-speedometer reading, keep setup ultra simple.
The adaptor uses PID control of the cable speed to provide quick, smooth operation as well as preventing overdriving or damaging the speedometer needle. Consider this the most precise and easiest to use cable-drive unit on the market!

  • These Chevrolet Performance automatic transmission controllers include the wiring harness, controller, software, and laptop hookup. They are designed to allow for the use of electronically controlled transmissions in early model vehicles. Chevrolet Performance automatic transmission controllers are fully programmable for upshift, downshift, part throttle and wide-open shifts, and shift firmness. They come preprogrammed--just enter your rear tire diameter and rear axle ratio and go, or create your own custom shift characteristics. Chevrolet Performance automatic transmission controllers were originally developed by GM Racing for off-road truck racing. They have the ability to record and graph drag racing data like time, speed, shift point, engine rpm, and more.
