New OE-spec silver hex-flange bolts that fasten the turbocharger down to the top of the turbo pedestal on 1999-2003 Ford 7.3L Powerstroke engines with the factory GTP38 turbocharger. Sold as a complete 2-bolt set — same silver zinc-plated finish, same M8 x 1.25 thread, same hex-flange head as the OE Ford / Navistar hardware.

Correct Bolt for the 99-03 GTP38 Pedestal

The 99-03 GTP38 pedestal uses two (2) M8 x 1.25 hex-flange bolts to secure the turbo to the top of the pedestal casting. This is different from the 94-97 TP38 pedestal, which uses four turbo-to-pedestal bolts. If your truck is a 1994-1997 7.3L, order the SL-320-006 kit instead.

When to Replace These Bolts

• Anytime the turbo is removed from the pedestal — bolts stretch under torque and should not be re-used
• Rusted, seized, or rounded OE bolts that will not come loose cleanly
• Oil weeping past the turbo-to-pedestal joint from under-torqued or missing bolts
• Any turbo swap, wicked-wheel install, pedestal rebuild, up-pipe replacement, or EBPV delete job

Component Breakdown — What's In the Box

• 2 silver hex-flange turbo-to-pedestal bolts — M8 x 1.25 thread, zinc-plated for corrosion resistance

Material & Finish

Grade 8.8 medium-carbon alloy steel with a silver zinc plating. Rated for 18-25 ft-lb of torque per the Ford service manual, well within the fastener's yield strength. Same thread pitch and head profile as the OE bolt so factory sockets and torque wrenches work without adapters.

Install Notes

Torque the two turbo-to-pedestal bolts to 18 ft-lb per the Ford service procedure. Do not exceed 25 ft-lb — over-torquing pinches the turbo pedestal O-rings and causes oil leaks. Always replace the pedestal O-rings any time the turbo is unbolted from the pedestal.

Features

• Direct OE replacement — same thread, same length, same head profile
• Grade 8.8 alloy steel for repeatable torque without stretching
• Zinc-plated silver finish resists corrosion in the valley heat environment
• Set of 2 — everything needed for one turbo installation
• Fresh hardware for every turbo removal — never reuse stretched bolts
