The Lightweight Aluminum case with a lightened steel spool and Standard gear set can be used where weight is critical, the vehicle is light, and impact loads are relatively low. Drag Race applications include 4-link Super Comp Dragsters, Altereds, Comp, and lightweight door cars. This package contains the Lightweight aluminum case, Strange billet aluminum pinion support (N1922), lightweight steel spool, Standard gear, and chrome moly 1350 yoke with u-bolts. Upgrade available is a 40 spline L/W steel spool. Options include a ball bearing pinion support, lightened ring gear, MicroBlue service, and computer pick-up collar. Higher horsepower vehicles, especially those using a throttle stop, will opt for the PRF165 which contains a Pro gear. It is also very common to upgrade to a 40 spline L/W steel spool.
STRANGE LIGHTWEIGHT ALUMINUM CASE Lightweight aluminum cases are ideal for vehicles where unsprung weight is extremely critical and gear life is not a major concern. Dimensionally very similar to the Pro Iron case, but uses high tensile aluminum alloy and forged aluminum main caps. Since the case is responsible for holding together the gear set and spool, the application should be carefully considered before a purchasing this case. Typical Drag Race applications are Super Comp Dragsters, Altereds, and very lightweight cars. This case is not recommended for Street or Street/Strip. A Strange Engineering associate will be happy to assist you with your decision. Available bore sizes are 3.062” and 3.250”.
