Overview
Not a cam-only part, the Truck Norris kit bundles a camshaft with springs, seals and pushrods for LS truck engines. It is Brian Tooley Racing's answer for owners who want the whole valvetrain refresh in one box.
A kit saves sourcing the supporting parts one by one, which is the reason to choose it over a cam alone. What the listing leaves out is the engineering detail: no duration, lift or lobe separation figures, and no fit by year.
Who it's for
LS truck owners and builders planning a cam swap who trust Brian Tooley's grind and want the supporting parts included. Anyone who needs duration and lift numbers to match heads and converter has to ask the seller.
Pros and cons
- Springs, seals and pushrods included
- Covers many LS truck engines
- Made by a known cam designer
- Single-box parts bundle
- Duration and lift not listed
- Model years not listed
- Marketing copy replaces real specs
- Brand and model fields are inconsistent
Performance notes
Lobe profile sets how long and how far the valves open, which drives the power band, idle quality and converter needs. Because those figures are missing here, the result on any engine rests on the maker's grind and the supporting parts rather than numbers you can check.
Where it stands among camshafts
