Product Details

These exhaust-side retainers are a direct companion to Supertech spring kits such as the SPRK-MCB48 and SPRK-B58B.

Key Features:

  • Military-grade titanium alloy construction — significantly reduces valvetrain reciprocating mass compared to steel retainers
  • CNC machined for precise dimensional tolerances and a tight, reliable fit
  • Compatible with Supertech beehive spring SPR-FE20BE and dual spring kits for the B48/B58 engine platform
  • Engineered for high-RPM performance builds exceeding 7,500 RPM where OEM retainer limitations become a concern
  • Designed for use with OEM triple-groove valves — no valve replacement required

Supertech Performance retainers are manufactured to the same exacting standards as the rest of their valvetrain lineup, using computer-aided engineering to optimize fitment and durability under extreme racing conditions. Paired with Supertech valve springs, these retainers help eliminate valve float and valvetrain instability at elevated engine speeds, giving performance and racing builds a critical competitive advantage.

Part Information:

  • MPN: RET-BMB48-TE-8
  • Material: Military-certified titanium alloy
  • Quantity: 8 retainers (exhaust side)
  • Compatible Spring Kits: SPRK-MCB48, SPRK-B58B, SPR-FE20BE
  • Companion Part: RET-BMB48-TI-8 (intake side)
