Drop in replacements for hydraulic lash adjusters (13750-70020) that include a retaining groove for a clip to attach to the rocker. This adds a security mechanism if the rocker looses spring pressure due to a valve float/bounce situation.
Model: Yaris GR, Corolla GR
- 12x Denstoj Hydraulic Lash Adjusters
- 12x Denstoj Rocker Retainers Clips.
Q: Are they compatible with the Kelford springs and camshafts?
A: Yes as they are drop-in replacements for the OEM hydraulic lash adjusters and work with the existing rockers.
Q: Do you also recommend upgrading the valve springs?
A: If you’re raising the rev-limit above factory specification or increasing boost pressure, yes, we also recommend upgrading the valve springs.
However, if you’re planning to keep it mainly stock, you’re better of using the original valve springs. This is so that you’re not adding unnecessary load into the valve train.
Q: Can I install your rocker retainers without removing the camshafts?
A: It's possible and we've done it but we'd recommend dropping the timing. It's easier in the long run.
Q: To install your rocker retainers, does the whole engine have to come out and roughly how long does it take?
