PRODUCT DESCRIPTION: So what is the downside to mod racing? Most would say nothing, its a mans class, its what separates the men from the boys, and of course its what hits the pocket book and your drivetrain the most! First you have drivetrain wear, than you have a Sherman tanks worth of steel components as your main driving aide, and lastly with more weight comes less efficiency. And where there is a problem, MIP has a solution! Introducing MIPs all New Bi-Metal Shiny Drive System! Featuring a never before seen two piece bi-metal outdrive that is comprised of both 7075T6 aluminum and high grade heat tempered machine steel, this diff alone will shred 30% off of your OEM rotating mass, which equates to quicker acceleration without compromising strength. Being that the diff outputs are steel, its fully compatible with the highly successful MIP Roller Pucks which have a 360 degree wear pattern and of course are 100% replaceable! Ditch 30% of your rotating mass, keep more money in your pocket, say NO to replacing your bones and outdrives simultaneously, and say YES to MIPs all new Bi-Metal Drive system for your modified 2wd buggy. Always Made 100% in the USA!
