springs at any price.
*H-11 Alloy is a metal often used for highly stressed structural
parts (such as aircraft landing gear) and also offers
resistance to thermal fatigue.
This 72 piece kit features:
Q: Which Material retainer should I get?
A - part 1: Titanium Retainers: offer an
extremely light weight choice for racers that are determined to
maximize performance down to each gram of the valvetrain. Ideal for
very high RPM race & sprint use or you plan to switch to solid
lifters or are building an all out race engine that will be
regularly inspected or torn-down to rebuild.
A - part 2: Steel Alloy retainers work perfect
whether competitively racing or daily driving. They offer excellent
weight reduction Vs. stock retainers, and are extremely strong.
This is the choice for a street car, or HPDE cars that are
expecting to go multiple seasons or years without opening the
engine for tear down.
VAC Tech Note:
** Please note that because we engineered this set from a clean
design; springs retainers and seats are all sold together as the
superior dual spring arrangement must be used with the correct
retainers and seats together and are not compatible with OEM
seats/retainers, therefore springs are not available separately
other than for replacements.
