Application and Fitment:

• Toyota 3S-GTE - Celica All-Trac/GT-Four (ST165, ST185, ST205), MR2 Turbo (SW20), Caldina (ST215, ST246) - Primary application
• Toyota 3S-GE (BEAMS) - Altezza (SXE10), Celica (ST202), MR2 (SW20) - Direct cross-reference; shares 3S-GTE flywheel thread specs
• Toyota 5S-FE - Camry, Celica, MR2 (naturally aspirated) - Also used in 5S block / 3S head builds
• Toyota 1FZ-FE - Land Cruiser (FZJ70, FZJ80, FZJ100/105) - REQUIRES 2 KITS (12 bolts total)
• Note: Verify your engine configuration before ordering

IMPORTANT - 1FZ-FE Land Cruiser Owners:

The 1FZ-FE is a 6-cylinder engine requiring 12 flywheel bolts. Since the ARP 203-2801 kit contains only 8 bolts, you must purchase two kits to complete the job. Do not attempt to install with fewer bolts than required - proper flywheel clamping requires all bolt positions to be filled and torqued correctly.

What's Included:

• ARP flywheel bolts (8 bolts per kit)
• ARP assembly lubricant
• Installation instructions
• Note: 1FZ-FE Land Cruiser owners require 2 kits (12 bolts total)

Installation Notes:

• Professional installation recommended
• Remove transmission and clutch to access flywheel
• Clean crankshaft flange and flywheel mating surfaces thoroughly
• Apply ARP assembly lubricant to bolt threads and under bolt heads
• Install flywheel and hand-tighten bolts
• Torque bolts in star pattern to ARP specifications
• Do not use OEM torque specs - use ARP recommended torque
• Reinstall clutch and transmission

8740 Chrome Moly Pro Series:

ARP's Pro Series bolts are manufactured from 8740 chrome moly steel, heat-treated to achieve 200,000 psi tensile strength. This is significantly stronger than OEM flywheel bolts, providing a substantial safety margin for high-performance applications. The 8740 chrome moly alloy provides excellent fatigue resistance, which is critical for flywheel bolts that experience repeated loading and unloading cycles with every clutch engagement.

12-Point Head Design:

The 12-point head style provides better tool engagement compared to standard hex (6-point) bolts. The 12-point design allows the socket to engage at more positions, reducing the chance of rounding and allowing more accurate torque application. The 3/4" socket size is standard and compatible with most torque wrenches.

3S-GTE Primary Application:

The 3S-GTE turbocharged engine, used in the Celica All-Trac/GT-Four (ST165, ST185, ST205), MR2 Turbo (SW20), and Caldina (ST215, ST246), is the primary catalog application for this ARP kit. The 3S-GTE's turbocharged power output and motorsport heritage make ARP flywheel bolts an essential upgrade for any clutch installation.

BEAMS 3S-GE Application:

The BEAMS 3S-GE, found in the Toyota Altezza (SXE10), Celica (ST202), and MR2 (SW20), shares flywheel thread specifications with the 3S-GTE, making this ARP kit a direct fit. The BEAMS engine's high-revving naturally aspirated character and popularity in performance builds make ARP flywheel bolts a worthwhile upgrade.

5S-FE Application:

The 5S-FE naturally aspirated engine, found in the Camry, Celica, and MR2, is also compatible with this ARP kit. The 5S-FE is particularly relevant for builds using a 5S block with a 3S head, where the shared flywheel bolt specifications make this kit the correct choice.

1FZ-FE Application (Land Cruiser - Order 2 Kits):

The 1FZ-FE 4.5L inline-6, found in the Land Cruiser (FZJ70, FZJ80, FZJ100/105), is compatible with this ARP kit but requires two kits due to its 12-bolt flywheel pattern. Always purchase two kits for 1FZ-FE applications to ensure all 12 bolt positions are filled and properly torqued.

Their fasteners are manufactured from premium materials to exacting tolerances, providing superior strength and reliability compared to OEM hardware.

Installation Tips:

• Always use ARP assembly lubricant on threads and under bolt heads
• Torque to ARP specifications - not OEM specs
• Use a calibrated torque wrench for accurate torque
• Torque in multiple passes using star pattern
• Replace flywheel bolts any time flywheel is removed
• 1FZ-FE owners: order 2 kits before starting installation

Perfect For:

• Toyota 3S-GTE builds (Celica All-Trac, MR2 Turbo, Caldina)
• Toyota BEAMS 3S-GE builds (Altezza, Celica ST202, MR2)
