H&R 29313-1 Street Performance Coilovers Mono-Tube Adjustable Lowering Kit

The H&R 29313-1 Street Performance Coilovers are engineered to deliver an exceptional balance of daily drivability and spirited performance. Built around a state-of-the-art mono-tube gas shock construction, these coilovers outperform traditional twin-tube shock absorbers in heat dissipation, response, and overall damping consistency.

H&R is widely recognized as the originator of the true street coilover system, and the 29313-1 reflects decades of suspension engineering expertise. Each shock is carefully valved to work in harmony with a progressive-rate coilover spring, engineered from the ground up as a matched system — not an afterthought. The result is a finely tuned suspension that feels composed during everyday commuting and engaging on more demanding roads.

Key Features:

• Mono-tube gas shock construction for superior performance over traditional twin-tube designs
• Fully threaded shock body allows precise, tool-adjustable ride height lowering
• Lowering range of approximately 1.0 to 2.5 inches (varies by application)
• Progressive-rate springs matched and tuned to each shock's specific valving
• Engineered for street use — comfortable enough for daily driving, capable enough for the serious enthusiast
• Complete bolt-on coilover system for straightforward installation

Whether you're a daily driver looking to sharpen your vehicle's stance and handling, or a dedicated tuner seeking a high-quality suspension foundation, the H&R 29313-1 Street Performance Coilovers deliver the ride quality and adjustability that H&R has built its reputation on.
