ARP rod bolt kit 201-6104 fits the BMW E30 M3 S14 2.3L engine from 1988 to 1991. These high-strength fasteners replace OEM bolts to secure connecting rods under high-rpm stress. Built for durability they maintain clamp load through heat cycles and high horsepower applications.

Key Features

  • ARP2000 Alloy Steel: Rated at 200,000 psi tensile strength resists fatigue and stretching in boosted or naturally aspirated S14 builds

  • Precise Fit: Application-specific dimensions match BMW S14 connecting rods for drop-in replacement without machining
  • Complete Set of 8 Bolts: All hardware included covers full inline-4 engine reassembly with matched components
  • Track-Proven Design: Handles street driving track days and drag racing with consistent performance

Product Notes

  • Inspect connecting rods for wear before installing new bolts
  • Apply ARP Ultra-Torque lubricant on threads and under bolt heads
  • Compact lightweight kit ships quickly without oversize fees

Installation Notes

  • Professional installation recommended.
  • Torque to ARP specs: 59 ft-lbs initial plus 90 degree angle turn using ARP lube
