H&R 39211-11 Premium Performance Coilover Kit with Aluminum Front Struts

The H&R 39211-11 Premium Performance Coilover Kit brings race-inspired engineering to street-driven vehicles. Built around H&R's proven mono-tube gas shock construction, this system delivers a significant step up over traditional twin-tube shock absorbers, offering sharper response, better heat dissipation, and improved consistency under repeated use.

What sets the Premium Performance line apart from H&R's Street Performance coilovers is the use of fully-threaded, hard-anodized aluminum front strut bodies. This design reduces front unsprung weight by 30 to 40% compared to stock struts, directly improving suspension articulation, steering feel, and overall handling response. The aluminum struts receive a black hard-anodize treatment for corrosion resistance, long-term durability, and a clean aesthetic.

Ride height is fully adjustable via threaded spring seats, with a front lowering range of 1.2 to 2.0 inches and a rear lowering range of 1.0 to 2.0 inches. Each shock is custom-valved and paired with progressive-rate springs, tuned to balance spirited driving performance with everyday ride comfort. The kit includes adjustment wrenches for convenient at-home setup.
