RT Off-Road Control Arm Brackets

Front coil springs need control arms to center the axle evenly under the vehicle, while driving down the road or flexing over obstacles. RT Off-Road control arm brackets are designed with extra steel around the mounting holes, where stock units are prone to failure. In order to dial-in the caster, these brackets use a slotted bolt design. Front coil springs make for a comfortable ride—and with sway bar disconnects, they have incredible flex, too. Keep your Jeep's front axle from getting out of whack with RT Off-Road control arm brackets. They're available for a wide range of applications, from 1984 and up.

Biondo Marine Digital Trim Controllers

Biondo marine digital trim controllers designed by Digital Delay, Inc., are designed and manufactured for use in drag boats. They have two outputs controlled by two independent 4-stage timers. Typically, one output is used to trim the motor while the second output controls a ram to lift the motor. The timers can be started together or independently, and both timers must be armed before they will cycle, keeping them from restarting if you have to let up on the throttle momentarily. The arming can be done by a remote switch or by pressing the enter key on the keypad. Features: * 12 and 16 V compatible * Microprocessor controlled timing * Retains all numbers, even when power is disconnected * Large, illuminated display and keyboard for day/night reading * Self-test mode on all display functions * Positive feel keypad for simple and quick programming (even with gloves on) * Scrolling on keypad for quick number changes * Timing can be set to the thousandths of a second on Stage 1 and 2 * Output is reversible (battery-to-0 V or 0 V-to-battery) * Arm feature keeps the timers from recycling * Two independent timers
