Moroso's Brute Strength Differential is the strongest clutch-type differential available.
Features:Legal for all drag race associations
The thicker, webbed flange on the reinforced case reduces ring gear deflection, prolonging ring and pinion life
Spider gears are forged from H-11 aircraft steel bar stock making them 50% stronger than Chevrolet "service package" gears
Twenty-two friction discs (stock units have only 18 discs) improve bias ratio (torque split) by over 100%; heavy shock loads are more evenly distributed to the side gears for greater durability
Extra-thick heat-treated spring plates and special chrome silicon springs yield over 800 lbs. of preload on the disc packs to insure an even bias ratio to the rear wheels for maximum traction
Designed for 4.10 through 6.14 ratios (4-series)
Stock-type axles are retained with original "C" clips; spacers or costly installation kits are not required
Use only Moroso Climbing Gear Lube Nos. 710-34800 or 710-34801
Note: Brute Strength Differentials are limited-slip devices designed specifically for racing applications. They are not recommended for street use as they can produce severe "chatter" when turning corners.
