B&M Shift Improver Kit - GM 4L60E Transmissions.
Performance Made Easy, Two Kits in One!
B&M Shift Improver Kits are the easiest and most affordable way to gain automatic transmission performance results. B&M's kits modify an automatic transmission's shift timing in order to increase shift firmness and in-turn improve durability. These dual stage performance shift kits are application specific and contain your choice of Heavy Duty or Street/Strip configurations. Shift Improver Kits provide well appointed, crisp shifts delivering unmatched performance.
Stage 1 - Heavy Duty:
Firm, positive shifts without loss of passenger comfort for improved performance in all street vehicles. Recommended for normal passenger vehicles and tow vehicles.
Stage 2 - Street/Strip:
Provides positive shifts for high performance street use or competitive events. This configuration is for the enthusiast who wants hard, fast shifts.
