SHG Motorworks Steering Rack Slider Honda Civic Type R EP3 Integra DC5

The SHG Motorworks rack slider design was drawn up to alleviate failing OEM sliders in our DC5 race car. Especially with racing slicks, we found that the stock slider was just not up to the task. Oddly enough, the European CTR community has also been dealing with creaking, clunking racks and vague, wandering or sticky steering for years.

There are a few reasons for these symptoms. First, the factory grease that was used left a lot to be desired. Between inconsistent application on the assembly line, and the high heat coming off the exhaust manifold, we find the factory grease to be in poor condition when servicing racks. Second, the design of the OEM slider is minimal at best. Considering the huge forces applied to the steering rack especially during track use, there are only 4 small pads that contact the rack housing. These 4 contact points are responsible for keeping the inner tie rod bracket traveling on a smooth flat plane, prevent it from twisting, and to also keep the inner rack bar from rotating which will affect the lash of the rack and pinion gear teeth either causing loose steering or binding of the gears.

We addressed these points of failure by looking at the design of a new OEM slider and the rack housing itself. Taking careful dimensions and consideration for all functions of the slider (including stopping the rack at proper full lock position) we designed a new part made from DuPont black Delrin material which is extremely strong and has self-lubricating properties.
