 Bully Dog Fuel Pin: Additional 40 horsepower for the Dodge 1988-1993 12 Valve Dodge Cummins

Bully Dog Valve Springs: Engineered to be the absolute best money can buy
Bully Dog Valve Springs 

These higher tension springs help prevent valve floating, which can occur on an engine that is producing over 50 lbs of boost. Taking this step is mandatory once a vehicle is upgraded with nitrous or a twin turbo set up. In high boost situations you run the risk of serious damage to your valves using stock springs.

Bully Dog Torque Plate 

Designed to fit the 12-valve, 1994-1998 Dodge Cummins Diesel engines. Horsepower gains range from 30-100 depending on the year of the vehicle and transmission style.
 
 
 
 
 
 
 
 

Bully Dog J-Hook: A quick way to increase your boost
Bully Dog J-Hook

Available for the 2001-2002 24 Valve Cummins engine equipped with the 47RE automatic transmission. The J-Hook regulates the waste gate, facilitating greater boost numbers which rise even higher as performance modifications are added. The higher volume of air will also help keep exhaust temperatures down.
