New at Summit Racing: TCI Low Gear Planetary Sets
Drop in lower gearing for off-the-line acceleration in everything from drag race heroes to tow vehicles.
Why They’re Cool: These Low Gear Planetary Sets offer lower first and second gear ratios. That significantly increases vehicle acceleration and lessens the rpm drop between gears for better all-around performance.
The gear sets for GM 4L80E transmissions have heavy-duty CNC-machined billet construction that increases load capacity by as much as 17 percent, making these planetary sets much more durable than OE.
The gear set for Ford C-6 has a six-pinion, low drag design that offers greater strength and significantly lower drag through the use of low friction, high-quality bearings in place of the standard brass thrust washers.
Applications
• GM TH-400, 2.75:1 first/1.48:1 second or 2.97:1 first/1.57:1 second gear ratios
• GM TH-350, 2.75:1 first/1.52:1 second gear ratios
• GM 4L80E, 2.75:1 first/1.57:1 second or 2.97 first/1.57:1 second gear ratios
• Ford C-6, 2.71:1 first/1.54:1 second gear ratios
