H&R 29258-6 Street Performance Coilover Kit - Monotube Adjustable Lowering System

The H&R 29258-6 Street Performance Coilover Kit is a complete, vehicle-specific coilover suspension system engineered in Germany for drivers who demand a balance of daily comfort and precision handling. Designed for the Volkswagen Eos (Typ 1F) with a 55mm front strut diameter, this kit delivers a meaningful drop in ride height without sacrificing the drivability needed for everyday use.

Unlike conventional twin-tube shock absorbers, the H&R 29258-6 uses monotube gas shock construction to provide more consistent damping response and better heat dissipation. The true threaded shock body — not a sleeve-over imitation — allows precise ride height adjustment by repositioning the spring seats, lowering the center of gravity for reduced body roll and improved cornering performance.

Each shock is custom-valved using H&R's exclusive dynamic damper technology and paired with a precision-wound progressive-rate spring. This pairing means the suspension remains compliant over rough road surfaces at everyday speeds, yet firms up progressively under harder driving conditions, keeping handling sharp without introducing harshness.

Key Features:

• Monotube gas shock absorbers for precise, stable damping in all conditions
• Fully threaded shock body for adjustable ride height — front lowering 1.2" to 2.0", rear lowering 1.0" to 2.0"
• Progressive-rate springs, custom-tuned to match shock valving
• Trapezoidal thread design reduces seizing after extended use
• Zinc-phosphate coated shock tubes for corrosion protection
• Built-in bump stops and helper springs included
• German TÜV quality approved
• Fits VW Eos Typ 1F (55mm front strut clamp diameter) — models from May 2006 onward

Professional installation and a post-install alignment are recommended. H&R Street Performance Coil Overs are backed by a 2-year warranty to the original purchaser when used within the specified adjustment range. Made in Germany.
