OPTIONAL EQUIPMENT
#400GSA 2.75 / 1.57 CUSTOM RATIO PLANETARY GEAR SET $ 599.00
This gear set is used to increase torque multiplication/rotating speed in the transmission in first and second gears. This improves acceleration with heavy vehicles and numerically low final drive ratios. (IE: 3.23, 3.42, 3.73)
#400GSB 2.32 / 1.48 CUSTOM RATIO PLANETARY GEAR SET $799.00
This gear set is used to reduce torque multiplication/rotating speed in the transmission in first gear. This improves traction in applications that overpower the rear tires on the launch. This is common with numerically high final drive ratios. (IE: 4.10, 4.56, 4.88)
#400GSC 2.10 / 1.40 CUSTOM RATIO PLANETARY GEAR SET. $1549.00
This gear set is used to reduce torque multiplication/rotating speed in the transmission in first gear. This improves traction in applications that overpower the rear tires on the launch. This set works great with high horspower cars running drag radials.The close ratio design keeps the engine in its peak torque curves on gear changes improving performance.
#400GSD 2.48 / 1.48 RATIO SEVERE DUTY STRAIGHT CUT GEAR . $499.00
This is the facory heavy duty straight cut planetary gear set produced by General Motors for extreme duty applications. This gear set is recomended for competition applications with vehicle weight over 4200 pounds.Great for trucks used in mud pulling ,baja/off road that require the stock gear ratios.
#4L80EDS FILLER TUBE AND DIPSTICK W/LOCKING CAP $115.00
STAGE 2 4L80E TRANSMISSION
The Stage 2 GM4L80E is built for street/strip, and drag racing vehicles producing up to 1500 horsepower/1500 foot pounds of torque. Are you tired of intermediate sprag failures? The Stage 2 transmission is assembled with our CNC machined unbreakable oversize 36 element sprag and outer race eliminating sprag failuresand comes standard with our 300Msteel billet input and intermediate shafts and E4340 steel billet forward clutch hub. Each transmission is professionally assembled and given a thorough road test in our test vehicle to ensure performance and quality prior to shipping. Be sure to check out our custom gear ratios under “Optional Equipment”.
