Our aluminum cases are made from 356 T6 aluminum, our bearing caps are from one-piece billet, with a through bolt design and extra material is added to the bearing caps. This results in 50% less deflection that can occur with other units on the market.
The "through bolt" means that the differential bearing cap bolts are installed all the way through the differential housing itself. This makes it so that there is no chance of the bolts stripping out of the alum housing under punishing force.This Nitro Spool is the unit of choice for drag racing and hardcore off-road use. The no-frills design of the spool features no moving parts and provides 100% traction to both tires at all times. When traction & strength can not be compromised, Nitro's spools won't let you down.
