A single 0.500 in. carburetor spacer is one of the most common street and bracket racing changes, and it is just enough extra height to leave factory carburetor bolts short on thread. These 2.0 in. studs restore correct engagement for a 0.500 in. thick carburetor flange running one thin spacer. The 12-point nuts are the reason to choose a stud kit over bolts on a crowded intake, since the smaller across-flats size lets a socket drop over the nut without hitting the carburetor body.

Moroso 37965 Features:

• Four 5/16-24 x 2.0 in. studs for a 0.500 in. flange plus one 0.500 in. spacer.
• Bullet nose ends let nuts start square and reduce cross-threading.
• 12-point nuts improve socket clearance around fuel bowls and linkage.
• Hardened flat washers protect the carburetor flange under clamp load.
• Black oxide finish for corrosion resistance in an underhood environment.

Note: torque the nuts evenly in a crossing pattern so the spacer and both gaskets seal without distorting the carburetor base.
