The Gigglepin TopHousing Bush Kit is an upgrade for the standard Warn 8274/8074 top housing, the two bronze bushes and spacer replace the needle roller bearings within the main gear for increased strength and reliability. The main gear in the standard Warn 8274 top housing is supported on its shaft by two needle roller bearings. These can move up inside the gear allowing the gear to run at an angle which can cause catastrophic damage not only to the main gear, but also the intermediate gear in the lower housing. This bronze bush kit eliminates the chance of this happening, increasing the strength and reliability of your top housing. The two bronze bushes are also rifled to improve oil flow within the gear. Comes supplied with 2 x Bronze Bushes, Replacement Spindle Shaft, Retaining Screw and Fitting instructions.
