TH700-R4/4L60E 29-Element Input Sprag fits GM

TH700-R4/4L60E 29-Element Forward Input Sprag – Compatible for GM 1982-2013

Stop blowing up your TH700-R4 or 4L60E with this bulletproof 29-element forward input sprag.

The factory 16-element sprag is the #1 weak link in any performance or high-mileage build — it rolls over under torque, grenades the forward clutch pack, and leaves you with no upshift or drive. This upgraded 29-element version nearly doubles the holding capacity, eliminates rollover completely, and delivers rock-solid 1-2 upshifts even behind modified LS engines, big cams, or superchargers.

Perfect upgrade for:

• Chevrolet Camaro, Corvette, Silverado, Tahoe, Suburban
• GMC Sierra, Yukon
• High-horsepower street/strip cars and light towing trucks

Symptoms of a failing stock sprag:

• No 2nd gear or delayed/harsh 1-2 shift
• Ratcheting noise under acceleration
• Forward clutch burnout on teardown

Drop this HD sprag in during your next rebuild and never worry about the input sprag again.

Add the toughest TH700-R4/4L60E input sprag available to your cart today and build it to survive!
