Keep Your LS Engine’s Valvetrain Under Control with COMP Cams Beehive Valve Spring Kits
Valve springs that don’t efficiently manage dynamic valvetrain stress can experience fatigue, binding, and breaking. This can lead to valve float at high RPM, premature wear on other components, and even severe engine damage.
COMP Cams’ Beehive Valve Spring Kits for LS engines will solve those issues. The unique Beehive™ shape places the maximum area of the wire at the point of highest stress. That allows them to handle high levels of valvetrain stress more efficiently, eliminating damaging harmonics to improve high-RPM horsepower and durability. The springs also have less pressure for better valve control and reduced weight.
COMP Cams’ Beehive Valve Spring Kits are available with springs rated to .600 or .625 inch of valve lift. and come with matched retainers, locks, valve seals, and spring seats. The .625-inch springs are available with your choice of tool steel or lightweight titanium retainers.

TCI Machined and Forged Flexplates Will Live Behind Your High-Stress LS Engine
High RPM and high-stall torque converters put a lot of stress on drivetrain components, including the flexplate. A TCI Machined or Forged Flexplate can handle what your LS engine dishes out.
The flexplates are SFI 29.1 or SFI 29.2-approved depending on the application. They’re made from precision-ground, 1/4-inch thick A514 or A36 steel plate that is much thicker and stronger than the OEM flexplate material. The 168-tooth flexplates have a heavy-duty ring gear for added strength.
Summit Racing also carries TCI’s Lightweight Forged Flexplate for LS1 engines. Built to withstand 12,000-plus RPM, the SFI 29.2-approved flexplate has CNC-milled pockets and lightening holes to reduce rotating mass and decrease weight. Other features include a hobbed-on ring gear and robotic TIG-welded converter spacers.
TCI Machined and Forged Flexplates are available with six- and eight-bolt crank-to-flexplate configurations. There are versions to accommodate GM TH-350, TH-400, TH-700-R4/4L60, 4L60E, and 4L80E transmissions.
