Customer Reviews
- Neoprene seal By James (posted on 19/02/2026)
- First time using a neoprene seal and not a rope one. Seal went in fine and no leaks since run in.
- good By Steven (posted on 20/09/2025)
- good product
- Top notch upgrade By RIK (posted on 19/09/2025)
- Easier to fit than the old rope and I can turn the motor to dial in the cam unlike the rope seals. Haven’t run it yet but I filled the void with oil and not a drip escaped so it should be a dry undercarriage which is rare for a Hemi 6
