H&R 29413-1 Street Performance Coilover Kit

The H&R 29413-1 Street Performance Coilover Kit delivers the ideal balance of lowered stance, improved handling, and daily-driver comfort. Unlike conventional twin-tube shock absorbers, these coilovers are built around a monotube gas shock construction that provides more precise damping response and better heat dissipation — a direct result of H&R's decades of motorsport engineering applied to street use.

The fully threaded shock body allows for straightforward, repeatable ride height adjustments without compromising suspension geometry or ride quality. Each shock is individually valved to work in concert with a precision-wound progressive rate spring, so the system remains compliant over everyday road imperfections while firming up predictably under hard cornering or braking loads.

Key Features:

• Monotube gas shock construction for superior damping response vs. traditional twin-tube designs
• Fully threaded shock body for adjustable ride height — no sleeve-over imitation design
• Vehicle-specific progressive rate springs matched to shock valving from the ground up
• Front lowering range: approximately 1.2" – 2.2"
• Rear lowering range: approximately 0.75" – 1.7"
• Lowers center of gravity to reduce body roll during cornering
• Suitable for daily drivers and performance-oriented street use
• Engineered and manufactured in Germany by H&R Spezialfedern

H&R pioneered the true bolt-on coilover system for street vehicles and remains a benchmark in the segment. The 29413-1 kit is a complete, matched suspension system — not a collection of mismatched components — making it one of the most straightforward performance suspension upgrades available.
