H&R 28907-11 Street Performance Coilover Kit Mono-Tube Adjustable Lowering

The H&R 28907-11 Street Performance Coilover Kit delivers a refined balance of ride comfort and handling precision engineered specifically for street use. Unlike conventional twin-tube shock absorbers, this system utilizes a state-of-the-art mono-tube gas shock construction that provides superior heat dissipation, faster response, and more consistent damping performance in all driving conditions.

H&R pioneered the true coil-over system for street applications and remains an industry leader through decades of suspension engineering expertise. Each shock absorber in this kit is individually tuned and paired with a progressive-rate coil spring designed from the ground up to work in harmony with the shock's internal valving — the result is a cohesive, finely calibrated suspension system rather than a collection of mismatched components.

The fully threaded shock body allows precise, tool-adjustable ride height lowering, giving drivers the flexibility to dial in their preferred stance without sacrificing ride quality. Whether you're a daily commuter seeking improved handling confidence or an enthusiast tuning for spirited performance, the H&R 28907-11 is engineered to perform.

Key Features:

• Mono-tube gas shock construction — superior to traditional twin-tube designs for performance and durability
• Fully threaded shock body for precise, adjustable ride height lowering
• Lowering range of approximately 1.0 to 2.5 inches (application-dependent)
• Progressive-rate springs matched and tuned specifically to each shock's valving
• Engineered for street use — balances daily-driver comfort with performance handling
• Complete bolt-on coilover system — all necessary hardware included

H&R is an OEM-level suspension supplier with a reputation built on precision German engineering. The 28907-11 coilover kit upholds that standard, offering a plug-and-play upgrade path to lower, better-handling, and better-looking stance for your vehicle.
