Product Details

The COMP Cams 54-330-11 is a Stage 1 LST (Low Shock Technology) hydraulic roller camshaft engineered specifically for GM LS 4.8L and 5.3L turbo engine builds. Developed and validated through rigorous Spintron and dyno testing, this camshaft is purpose-built for "cam only" forced induction applications where exhaust back pressure is unknown.

COMP Cams' proprietary Low Shock Technology (LST) lobe profiles are designed to maximize horsepower while significantly improving valve train stability at higher RPM. The lobe geometry is also gentler on valve springs, reducing load loss and extending valve train durability over time.

This camshaft also features COMP Cams' exclusive Micro Surface Enhancement (MSE) finish — a process that reduces surface peak roughness by 65% and improves the effective load-bearing area by 250%. This advanced finishing technology spreads contact stress across a larger area between the roller and cam face, enabling higher loads with less localized wear compared to traditionally polished camshafts.

All depends on how fast I get the bulbs!

I asked for chrome mirror covers for my 2015 V/W Eos so I hope they fit well

good so fare

Great

Ordered a couple of items. The first was a air intake kit. I had put in all my info for my truck and chose one from the list to order. Won't fit. Called to tell them and they asked if I had called manufacturer...ummm no. Said I needed to contact them to verify wrong part. They were closed, so went to website. The part they sent me was a universal fit- for cars, not trucks, but did find right model- $90 more. Called back autoplicity and was told I need to go through email to get an RA# to return wrong part- site says I can call. Been on hold for over 20 mins and still waiting. Hope the Nerf bars I ordered fit! Update- they called me back, got my RA#. Very pleased with how Nick handled things- it was what I expected the first time. He verified the NERF bars will fit and will be changing the website so the universal intake does not show on list for vehicles with larger air outlets. Changing my rating to show my satisfaction with how it was eventually handled.

Very descriptive about each part. Website is easy to use.
