Product Description

The Energy Suspension 8.3140G Rear Control Arm Bushing Set delivers a significant handling upgrade for the 2001-2005 Lexus IS300. Engineered from Energy Suspension's proprietary Hyper-Flex polyurethane formula, these bushings replace the factory rubber components that deteriorate over time, causing sloppy handling, poor wheel alignment, and increased tire wear. The black bushings feature graphite impregnation for self-lubricating properties, while the full floating, non-binding design ensures smooth suspension operation without the binding that can occur with solid bushings. Unlike OEM rubber that softens, cracks, and degrades from heat, oil, and road contaminants, Hyper-Flex polyurethane maintains its durometer and structural integrity for dramatically longer service life.

The firmer-than-stock material provides noticeably improved steering response and feedback, reduced body roll during cornering, and significantly less wheel hop during aggressive acceleration - making this kit especially popular among IS300 owners who enjoy spirited driving, drifting, or track days. Symptoms of worn rear control arm bushings include clunking noises from the rear suspension, vague steering feel, uneven tire wear, and difficulty maintaining proper alignment. This complete set includes everything needed to service both sides of the rear axle along with Energy Suspension's Formula 5 Prelube grease for proper installation. Whether restoring handling to a high-mileage IS300 or upgrading a performance build, Energy Suspension's rear control arm bushings deliver the durability and precision that has made them the most trusted name in polyurethane suspension components for over 38 years.
