PROLINE PRO-MT 4X4 REPLACEMENT SHOCK SEALS For RC Car

The Pro-Line PRO-MT 4x4 Replacement Shock Seals (Part No: PL4005-40) is a dedicated rebuild kit for the high-performance 16mm Big Bore shocks found on the Pro-Line PRO-MT 4x4 and PRO-Fusion SC 4x4. These seals are critical for maintaining a leak-free system and ensuring the ultra-smooth suspension travel required for high-speed bashing and technical jumps.

Key Features:

• High-Grade Silicone: Molded from premium silicone compounds that resist swelling or shrinking when exposed to various weights of silicone shock oil.
• Friction-Reducing Design: Engineered to provide a tight seal around the shock shaft while minimizing "stiction" (static friction), allowing the suspension to react instantly to small bumps.
• Complete Rebuild Set: Typically includes all necessary O-rings and clear spacers to fully refresh the bottom seal cartridge of a pair of shocks.
• Precision Fit: Specifically toleranced for Pro-Line's 16mm Big Bore shock bodies and shafts to prevent oil bypass and air ingestion.

Maintenance Tip:

When rebuilding your shocks, always apply a small amount of Green Slime or high-viscosity shock grease to the O-rings and shock shaft threads before assembly. This prevents the threads from nicking the new seals as you slide the shaft through the cartridge. Pro-Tip: If your shock shafts are scratched or pitted, replace them along with the seals; otherwise, the rough surface will quickly tear the new silicone, leading to immediate leaks.
