Product Details

RS-R Ti2000 Down Sus springs for the 2011-2020 Toyota Sienna (GSL30) bring the benchmark of Japanese spring engineering to your car. The proprietary chromium-nickel Ti2000 alloy is forged in a high-frequency induction furnace, producing a lighter, denser, corrosion-resistant spring that holds its ride height for the life of the vehicle — backed by RS-R’s Limited Lifetime Warranty against sag.

Ti2000 is RS-R’s flagship lowering spring — the only production suspension coil forged in a high-frequency induction furnace, using a proprietary chromium-nickel alloy. The faster heat cycle produces a denser grain structure that resists sag and corrosion so well that RS-R backs every Ti2000 spring with a Limited Lifetime Warranty. Expect a full Down-spec drop, sharper cornering, and measurable unsprung-weight savings versus the standard Down Sus.
