Hays Heavy-Duty Flexplates

Hays heavy-duty flexplates for high performance and competition engines are constructed from a thicker-than-stock steel plate. This enables them to withstand the stress of high-stall torque converters and high-rpm engines. While factory stock plates tend to crack around the crankshaft hub when punished under high-torque and rpm conditions, the thicker Hays flexplates can handle the force. These heavy-duty flexplates are supplied with a ring gear that is securely welded in place. All Hays heavy-duty flexplates are zinc-dichromate plated to resist corrosion and SFI-certified under specification 29.1.

Pacific Performance Engineering Premium High-Efficiency Spin-On Transmission Fluid Filters

Pacific Performance Engineering recognized the need for better filtration for the hard-working Allison 1000 and 2000 transmissions, so they developed the Premium high-efficiency spin-on transmission fluid filters. These superior filters are designed to address the limitations of the standard "shorty filter". Inside the PPE double-deep spin-on filter is 2.72 times more filter media surface area. This increased surface area allows improved fluid flow and filtering. The double-deep filter traps particles down to 15 microns—that is half the size of what the standard spin-on filter catches, which helps to create a cleaner flow of oil to vital internal components, resulting in smooth, more responsive shifts. Do more to protect your Allison transmission and realize better performance. Don't come up short. Spin-on PPE's high-efficiency transmission fluid filters!
