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!

Eliminate fastener problems with Stage 8's locking pressure plate fasteners. These pressure plate fasteners provide a simple, yet effective method to ensure that your fasteners do not loosen unexpectedly. The fasteners utilize mechanical clips to lock them in place, preventing them from backing out. The clips act like a small wrench on the bolt head to prevent the fastener from turning. Easier to use than safety wire, and cleaner than chemical thread lockers, the Stage 8 pressure plate fasteners will remain locked-in place, until you need to manually disassemble them.
