Projector Shrouds
Finding the Right Projector Shroud for Your Retrofit
Last month we had a customer bench a pair of 3 inch projectors, snap a shroud over the lens, and figure the job was basically done. It wasn't. He still had to trim the top edge to clear the housing lip before it would sit flush, which is normal, not a defect. Shrouds finish the look of a retrofit, but getting one that actually fits your projector size and your headlight housing is where most of the real work happens.
Fitment quirk worth knowing before you buy: a shroud made for a 2.5 inch projector will not fit over a 3 inch projector, full stop. But a 3 inch shroud can be stepped down to fit a 2.5 inch projector using centric rings, which are simple reducers that clip into the back of the shroud to shrink the inside diameter to a press fit. The Apollo 3.0, for instance, is rated compatible with both 2.5 inch and 3 inch lens diameters for exactly this reason. In practice, that means sizing up your shroud choice is usually safer than sizing down, then adjusting with centric rings rather than guessing on the smaller option.
Trimming is common no matter which size you land on. Housings are shallow in some spots and tight in others, so a Dremel with EZ Lock cutting wheels and a little patience is standard retrofit practice, not a sign you bought the wrong part. We also recommend JB Quik Weld to keep the shroud from vibrating loose over time. Still, none of that trimming will save you if the base diameter is wrong for your projector to begin with.
If you have not confirmed your projector size yet, start there before you shop shrouds. Our Retrofit Projectors guide will help you match the right projector to your housing so the shroud you pick actually seats the way it should.
