H&R 50415 Street Performance Coilover Kit

The H&R 50415 is a complete Street Performance Coilover Kit built around H&R's proven mono-tube gas shock construction. Unlike conventional twin-tube shock absorbers, the mono-tube design delivers more precise damping response and superior heat dissipation — making these coilovers equally at home on the daily commute and spirited weekend drives.

H&R engineers pair each shock with a vehicle-specific progressive-rate spring, carefully matched to the shock's valving to create a balanced, cohesive suspension system. Height is adjusted via easy-to-turn spring perches threaded directly onto the shock body — a true coilover design, not an imitation sleeve-over — giving you precise ride height control without compromising suspension geometry or ride quality.

Key Features:

• Advanced mono-tube gas shock construction for superior damping performance
• Fully threaded shock body for precise, adjustable vehicle lowering
• Front lowering range: 1.2" – 2.3"
• Rear lowering range: 0.75" – 1.5"
• Vehicle-specific progressive-rate springs matched to shock valving
• Easy-to-adjust spring seats for ride height tuning
• 100% manufactured in Germany to exceed ISO quality assurance standards
• Complete coilover system — all matched components included

H&R is the originator of the true coilover system for street use and has set the benchmark for ride quality and handling balance. The 50415 is ideal for drivers who want a meaningful drop in ride height alongside a noticeable improvement in cornering precision and overall suspension composure — without sacrificing day-to-day drivability.
