The Stage4R transmission kit is our intermediate-level trans upgrade kit that's built FOR drag racing, sled pulling, towing and daily-driving.

Note: A $200 converter core charge is included in price if bought with converter, reimbursed upon return of good core components to PPE. PPE product finish will vary.
