Dress up your GM TPI Unit with our awesome polished ARP Grade 8 stainless steel 12 point bolt kit!! The kit fits the 305 and 350 TPI small block engines.
ARP grade 8 stainless bolts have a tensile strength of 170,000 psi. That is slightly stronger than grade 8 steel bolts! Yet they are extremely resistant to rust and corrosion. More resistant than 304 stainless!! They have a reduced size hex and a flanged head for easier installation in tight spots.
We make these bolt kits from our stock of ARP metric bolts to our specs. All bolts and washers in the kit are polished. The kit consists of individually packaged and labeled component kits for the following:
Fuel Rail-Top Plate-Distributor Cover-Throttle body-Throttle Bracket-Idle Speed Motor Housing-TPI Runners
The Top Plate, Distributor Cover, and Idle Speed Motor Housing kits have polished 304 Allen Bolts in them.
