Springs
High Performance Valvesprings
We offer a line of valvesprings for the high performance and racing automotive markets.  Our springs provide:

More Power - Higher natural frequency and higher spring rate
result in better valvetrain control and ultimately more power!

Lasts Longer - Our customers have been experiencing an
unprecedented number of runs on a single set of springs!

Near Zero Load Loss - After extended usage these springs maintain their
load allowing performance at the end of a race equal to that at the start!

Less Expensive - Although these springs are a premium for steel springs,
they are significantly less expensive than the titanium alternatives!
Dramatic results that can be obtained through an improved spring
design.  Initially the spring surged wildly throwing the valve off the
nose of the cam and also allowed it to bounce when it slammed
closed.  In correctly selecting an LSM spring, the spring surge was
controlled and the valve lift followed the cam perfectly.  This test was
run at identical speeds with identical components except for the
spring.  At this stage in development the customer was able to select
a more aggressive camshaft and increase performance even more!
Custom Springs
We have manufactured valve springs in both titanium and steel for several proprietary markets.  Development of a
new spring is not inexpensive, but if you are looking to push the envelope of performance we can work with you to
develop a proprietary spring for your application.

L1000 Annihilator - This is the spring that the ultimate big lift motors have been
waiting for.  This spring is ideal for Pro-Stock and Top Alcohol.  The L1000 valvespring is
a monster.  It installs at 2.300” and can provide a full 1.250” of valve lift.  This spring has
offered performance an order of magnitude better than anything else ever tested.  These
springs should be used when the ultimate limits for cam profile, and lift need to be met.  
One of the secrets of the spring is the new material used in manufacturing them.  This
material outperforms any valve spring material that we’ve ever tested.

The L1000 is known as the AnnihilatorTM  since it is so far superior to any valve spring
ever produced.  This spring takes spring technology to the next level.
L700B/L700A - This triple spring is perfect for Comp Eliminator, Top Fuel, Pro
Mod and other high performance engines.
L400B/L400A - These double springs are ideal for Super Truck, Endurance,
Sprint Car, or Winston Cup.
L550 – High Performance - High Lift
This spring used for budget applications from high performance street to drag race.  
Good for applications of up to .850” lift.
L422 – High Performance - Street
This spring is a high quality spring suitable for applications where lower loads are
required.  It’s the perfect spring for IMSA-GTS or restrictor plate applications.  This
spring is ideal for any hydraulic street or mild solid lifter application.
L300 – High Performance - OHC
The L300 spring was developed for the demanding requirements of IRL racing and
is now the preferred spring by engine builders of VTEC Hondas and other high
performance import engine builders.

This spring is a direct replacement for many stock or aftermarket springs while
providing higher load and lift capability.
