These vibrations, caused by torque spikes during combustion, can damage engine components. Unlike stock rubber dampers, Fluidampr dampers work across a broader range of frequencies, crucial for engines with modified components. Rubber dampers are frequency-sensitive and may fail when engine dynamics change. Additionally, rubber deteriorates over time, leading to potential damper failure and engine damage on your Toyota Supra. \u003cbr\u003e\u003cbr\u003e\u003cspan style=\"color: #ff2a00;\"\u003eVehicle Fitment:\u003c\/span\u003e\u003cbr\u003e1987-1998 Toyota Supra \u003cbr\u003e1992-2000 Lexus SC 300 \u003cbr\u003e1993-2005 GS300 \u003cbr\u003e2001-2005 IS300\u003cbr\u003e(1JZ \/ 2JZ I6.

This torque spike is so severe that it not only turns the crankshaft, it actually twists the crankshaft ahead of its normal rotation and then the crankshaft rebounds. This twisting action is known as torsional vibration. When these torque spikes and forces get into phase with the natural frequency, critical torsional harmonic vibrations occur and can be seriously destructive to the bearings and the crankshaft. Dampers are designed to control those destructive vibrations. \u003cbr\u003e\u003cbr\u003eCritical harmonic vibrations occur numerous times in a engine’s operating range. Stock rubber and elastomer-type dampers are frequency sensitive “tuned absorbers”, and work at only one critical frequency. In the case of a stock rubber damper, it is tuned for a factory engine’s critical harmonic vibrations. If you change the mass of pistons, rods, or the crankshaft, you change the natural frequency of the crankshaft assembly; therefore, the stock damper is no longer tuned to the new frequency of vibration, and you may be headed for early failure of expensive engine components. Dampers also create heat while they work, and rubber is a poor dissipator of heat. This heat and the exposure to the elements deteriorates rubber, causing it to crack and change durometer, which then leads to inertia ring slippage, damper failure, uncontrolled torsional vibration, and costly engine parts breakage. \u003cbr\u003e\u003cbr\u003e\u003ca href=\"https:\/\/stmtuned.com\/collections\/fluidampr-products\" style=\"color: #afafaf;\" target=\"blank\"\u003e\u003cbr\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cspan style=\"font-size: .8em;\"\u003e See more Fluidampr Products\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/a\u003e","brand":"Fluidampr","offers":[{"title":"Default Title","offer_id":50561059225942,"sku":"FLU-840801","price":591.6,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/9531\/8102\/files\/fluidampr-harmonic-balancer-crank-pulley-sjz-toyota-supra-840801.jpg?v=1749196636","url":"https:\/\/www.speed-addicts.com\/en\/products\/fluidampr-harmonic-balancer-crank-pulley-sjz-toyota-supra-840801","provider":"Speed Addicts","version":"1.0","type":"link"}
