Description

2 Inner Springs to Convert 3k gsk to a 4k gsk.
94-98 Dodge 12 Valve Cummins

Not a cheap ass kit like a lot of others are selling & customer has issues with idle etc.

4000gsk = 1994-95 Inj pumps will rev to 3800rpm’s before defueling under load or more depending on how tight you set the retainer nut.

1996-98 pumps will rev to approx 3700rpm before defueling under load or more depending on how tight you set the retainer nut.

We highly suggest installing HD valve springs on intake and exhaust valves if using the 4000gsk.

Contents = Two ( 2 ) smallest springs in picture only
