Eliminate stud flex and help prevent stud breakage by stabilizing your valve train with a
JOMAR Pro-Model stud girdle, precision CNC-machined from premium 6061-T6 aluminum and anodized
gold to resist corrosion. Spring-loaded JOMAR Pro-Model girdle bars offer easy installation
and quick adjustment, and are engineered to fit more cylinder head applications than those offered
by anyone else in the industry.
