H&R's Sport Spring kit is a complete set of four progressive-rate coil springs for the 4L-generation Audi Q7 without air suspension. Each spring is made in Germany from 54SiCr6 steel and is shot-peened, a process meant to extend service life. Stock springs leave the body sitting high, while these lower the center of gravity and reduce body roll, which is where most of the handling gain comes from. Because the springs are delivered with ABE or TÜV approval, they are a documented option for street use, not just a show part.
Fitment is aimed at the 4L Q7 non-air setup, and the lowering is modest, about 1.4 inches up front and 1.3 inches at the rear, enough to tighten the fender gap without a harsh ride. The springs work with factory shocks or aftermarket shocks that fit stock springs. Installation is a typical coil spring swap, so a jack, jack stands, a spring compressor, and an alignment afterward are the practical requirements. Searchers looking for H&R 29107-1 4L Q7 lowering springs, Q7 non-air sport springs, or Q7 3.0 TDI handling upgrades will find this kit matches their application.
