LS3 Defender 90Potent Powerplant Mated To A 6L80-E Six-Speed Transmission

Under the Defender’s hood is an GM LS3 6.2-liter V8 engine. This is the same powerplant that propels the fifth-gen Camaro SS and C6 Corvette. The 376 cubic-inch engine pumps out 430 horsepower at 5,900 rpm and 425 lb-ft of torque at 4,600 rpm. Features include a cast-aluminum block; six-bolt, cross-bolted main caps; hypereutectic aluminum pistons; a hydraulic roller cam; and aluminum L92-type rectangular-port heads. Power is routed through a GM 6L80-E six-speed automatic transmission. A Land Rover LT230 1.211-ratio two-speed transfer case splits power to the front and rear axles. And on the topic of axles, both are stock heavy-duty Land Rover units with 3.54:1 gearing. Additionally, each axle end is fitted with EBC Brakes Greenstuff 6000 pads and GD Sport rotors. EBC’s Greenstuff 6000 series pads are made for 4×4 use. The company’s GD Sport rotors, designed for heavier vehicles, feature dimples and wider slots to enhance cooling.

LS3-Powered Defender 90 Air Ride Suspension, And More

The Defender 90 has an air ride suspension. Created by ECD Automotive Design, the suspension is fully adjustable at all four corners.

No matter the selected suspension height the LT265/65R18 (31.5-inch) BFGoodrich All-Terrain T/A KO2 tires on sawtooth-style 8-inch-wide wheels can travel without contacting the SUV’s body. And speaking of the Defender 90’s body, its sprayed in Portofino Blue gloss paint and most of its parts, including the grille and slats, are painted to match. Additionally, other exterior features include an LED work light on the driver-side rear, custom round light guards and checker painted in Zermatt Silver, and a custom dog ladder.
