SH TE2817B Crankshaft Sg (Sh28) (1)

Keep your racing engine at the front of the pack with SH Engine Spares. Specially engineered for the SH high-performance range of .12, .18, .21, and .28 engines, these factory-spec components are the professional choice for maintaining compression, RPM stability, and thermal efficiency. From knife-edged connecting rods to precision-lapped ABC piston and sleeve sets, SH spares provide the exact tolerances required for competition-level RC racing.

Key Features:

• Race-Grade Materials: High-tensile aluminum, hardened steel, and chrome-plated brass for maximum durability.
• High-RPM Optimization: Every internal part is weight-matched and balanced to reduce vibration and internal friction.
• Universal Pull-Start Support: Comprehensive range of recoil units, one-way bearings, and starter shafts for easy starting.
• Compression Tuning: Head shims and gasket kits allow for precise tuning based on fuel nitro content and ambient temperature.
• Full Carburettor Service: Replacement needles, O-rings, and venturis to restore a crisp, reliable idle and throttle response.

Pro Racing Tip:

When installing a new SH piston and sleeve, always perform a gentle "break-in" heat cycle. Applying a small amount of after-run oil to the new connecting rod bushings during assembly will significantly extend the life of your engine's bottom end.
