Accessories Shock Warmer
A dampers purpose is to absorb energy and convert it in to heat. Heat affects damping in a number of ways, oil viscosity changes becoming thinner as the temperature rises, heat also changes the density of the fluid due to expansion, and mechanical tolerances also change with temperature.
Manufacturers incorporate temperature compensation devices into their dampers which are effective at higher temperatures typically above 60°C. However track testing has revealed that it can take anywhere from 4 to 10 laps to reach this temperature dependant upon operating conditions. Shock dyno testing carried out by ourselves and Penske Racing Shocks has revealed that damping force can decrease by 10% during this warm up period. This means that the damper operation at the start of a race will be much stiffer than at the end of the race.
Pre-heated shock absorbers will ensure consistent damping performance throughout a race, improve tyre wear and increase rider confidence.
The warmer simply wraps around the shock body and fastens with Velcro. It will heat the shock to 60°C in 45 minutes, and is fitted with a long loop for quick removal.
It is available in two lengths for coil-over and non coil-over shocks.
