H&R 29120-2 Street Performance Monotube Coilover Kit

The H&R 29120-2 Street Performance Coilover Kit delivers a precision-engineered suspension upgrade for drivers who demand both enhanced handling and everyday drivability. Engineered and manufactured in Germany, these coilovers feature an advanced monotube gas shock design that outperforms conventional twin-tube absorbers by providing more consistent damping response and reduced unsprung weight.

Each shock absorber is custom-valved to work in direct harmony with H&R's progressive-rate springs, creating a finely tuned suspension system that excels from daily commuting to spirited driving. The fully threaded shock body uses robust trapezoidal threads for virtually infinite ride height adjustment, allowing you to dial in the exact lowering range that suits your driving style and conditions.

Key Features:

• Monotube gas shock construction — provides precise damping response and better heat dissipation than twin-tube designs
• Inverted (upside-down) shock design — reduces unsprung weight for sharper steering response and improved lateral force support
• Fully threaded shock body with trapezoidal threads — allows virtually infinite ride height adjustment of 1.0–2.5 inches on average
• Progressive-rate H&R springs — individually tuned to match shock valving for a balanced street and performance ride
• Zinc-phosphate coated shock tubes — triple zinc plating provides superior corrosion protection and an attractive finish
• Built-in bump stops and helper springs — ensure proper spring retention and suspension travel at full droop
• TÜV-approved construction — meets rigorous German quality certification standards (DIN ISO-TS 16949)
• Easy-to-adjust spring seats and locking rings — simplify ride height changes without specialized tools

H&R Street Performance Coil Overs are covered by a 2-year warranty to the original purchaser. Professional installation and a post-installation wheel alignment are recommended.
