Improve the reliability of your Toyota G16E-GTS engine and rev with peace of mind!

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 loses spring pressure due to a valve float/bounce/stick situation.

When the G16E-GTS first came out, we inspected the valvetrain and knew it would be a weak point. The rockers are floating, and we had experienced failures with a similar rocker setup in the FA20 engines in the Toyota 86 (which we have subsequently fixed). With the buzz around the GR Yaris, we started development on our rocker retainer solution, specific to the G16E-GTS engine.

The best solutions are simple. It's a clip that attaches to the rocker and a groove in the hydraulic lash adjuster that 'catches' the rocker if the valve spring loses pressure for a split-second due to a valve float situation.

If you haven't seen this solution before, it's actually quite common. More expensive performance engines such as the B58 BMW engine in the Supra and Lexus' flagship 2UR-GSE 5.0-litre V8 in the LC500 and RC F run rocker retainers. It's important to know that this is not a fix for valve float; instead, it adds a security mechanism to reduce the chance of a rocker dislodging if the valve spring loses pressure for a split-second due to a valve float situation.

It's a no-brainer preventive measure when building a high-performance engine. These should be stock on every engine Toyota makes.

Why Choose Our Rocker Retainer Kit?

Engine rebuilds can cost thousands of dollars, often ranging between $5,000 to $10,000, depending on the extent of the damage. Parts alone, such as pistons, valves, gaskets, can add up quickly. Our Rocker Retainer Kit, is a fraction of that cost and offers peace of mind by preventing a potential catastrophic failure that could leads to an expensive rebuild.

Protect your investment and drive with confidence knowing your engine is safeguarded.
