H&R 29525-2 Street Performance Monotube Coilover Kit

The H&R 29525-2 Street Performance Coilovers deliver race-bred suspension technology engineered specifically for street and occasional track use. Built around a high-quality monotube gas shock construction, these coilovers offer superior damping precision and consistent performance compared to traditional twin-tube designs — all without sacrificing daily-drive comfort.

Unlike imitation sleeve-over systems, the H&R 29525-2 features a true fully-threaded shock body that enables virtually infinite ride height adjustment. This design also improves heat dissipation and maintains structural integrity over time. Lowering is dialed in easily via adjustable spring perches, allowing you to fine-tune stance and weight transfer to your exact preference.

Each shock is custom-valved and paired with a vehicle-specific progressive-rate spring, creating a cohesive, finely-tuned suspension system. The progressive spring rate keeps the ride compliant over everyday road imperfections while firming up predictably under hard cornering, braking, and acceleration loads. Shock tubes are zinc-phosphate coated for corrosion resistance and a clean finish.

Key Features:

• Monotube gas shock absorbers for precise, consistent damping response
• True fully-threaded shock body — not a sleeve-over imitation — for accurate height adjustment and better heat dissipation
• Progressive-rate springs custom-matched to each vehicle-specific shock valving
• Front lowering range: 1.8" – 2.8" | Rear lowering range: 1.8" – 2.5"
• Zinc-phosphate coated shock tubes for corrosion protection and attractive finish
• Easy-to-adjust spring seats for dialing in ride height
• Lighter than twin-tube designs to reduce unsprung weight
• 2-year warranty to original purchaser

Professional installation and a post-install wheel alignment are recommended. The H&R 29525-2 is an ideal upgrade for enthusiasts seeking a meaningful suspension improvement that performs equally well as a daily driver or spirited weekend setup.
