Step 1
Which Engine Do You Have?
GM changed the hardware significantly across these three generations. Start by identifying your platform — it determines whether your engine has DOD/AFM, whether the heads need to come off, and which parts actually fit.
Gen IV LS — DOD/AFM
Has DOD/AFM
Full Parts Kit Required

Gen V EcoTec3 — AFM
Has AFM

Not sure which one you have? Use the VIN Decoder or RPO Code Lookup to confirm your exact engine before ordering parts.
Step 2
What Parts Do You Need?
Not every cam swap needs the same parts. These four categories cover the range from a simple cam-only swap to a full performance rebuild — and none of them require every optional upgrade.
Cam-Only Swap
Applies only to supported combinations — typically an NSR-style cam with healthy existing lifters and factory-compatible springs. Gen III LS only (98–06); Gen IV and Gen V always require the complete DOD/AFM-delete parts kit.
- Camshaft Required
- Cam retainer plate & bolts Required
- Timing cover gasket & front crank seal Required
- Balancer bolt (one-time-use TTY) Required
- Valve spring upgrade Optional
- Lifter replacement App-Dependent
Cam Swap With Valvetrain Upgrades
Adds valve springs, pushrods, seals, trunnions, and timing components matched to a bigger cam. Needed any time the cam moves outside factory-spring-safe territory.
- Valve springs matched to cam lift Required
- Chromoly pushrods, correct length Required
- Valve stem seals (if replacing lifters) Required
- Trunnion / rocker upgrade Recommended While Accessible
- Upgraded timing set Optional
DOD/AFM Delete & Lifter Replacement
A complete parts kit, not a partial swap. All 16 lifters, lifter trays, DOD/AFM block-off hardware, head gaskets, head bolts, timing components, gaskets, seals, fluids, and a matching calibration change are required — not optional.
- Non-DOD lifters (full set) Required
- Lifter trays / guides Required
- DOD/AFM block-off or non-DOD valley cover Required
- Head gaskets & head bolts Required
- Full gasket/seal set + fluids Required
- Calibration update Required
Complete Engine Refresh / Performance Build
Everything in a DOD delete plus the parts people add while they're already in there.
- Upgraded oil pump Optional Performance Upgrade
- Upgraded timing set Optional Performance Upgrade
- Premium lifters (non-OEM) Optional Performance Upgrade
- Long tube headers Optional Performance Upgrade
- Plugs & wires Recommended While Accessible
Required Needed for a correct, complete kit
Recommended While Accessible Cheap now, expensive later
Optional Performance upgrade, not required

Gen III LS Cam Swap Parts
Engines: 4.8L LR4/LM4, 5.3L LM7/L59, 5.7L LS1/LS6, 6.0L LQ4/LQ9. Vehicles: Silverado/Sierra 1500 & 2500, Tahoe, Yukon/Yukon XL, Suburban, Avalanche, Escalade, Camaro Z28/SS, Firebird, Corvette C5/Z06.
Platform note: This generation did not originally use AFM/DOD hardware. A cam-only NSR cam swap can be possible when the lifters are healthy and the selected cam is designed for factory springs — this is not the same as a DOD delete (there is no DOD/AFM system to delete on this platform) and it is not the same as a full lifter replacement or top-end refresh.
Cam-Only Swap — Budget Build (Required Parts)
Camshaft-only kit. Choice of NSR cam. No spring change required. Duration/lift/LSA for both NSR cams: verify by application.

Not included in the Budget Build: valve spring upgrade, lifter replacement, DOD/AFM delete (not applicable to this platform), valve stem seals (not part of a camshaft-only kit).
Full Top End — NSR Cam + LS7-Style Lifters (Complete Kit, Required Parts)
All 16 lifters replaced, 3-bolt non-VVT cam gear conversion, NSR cam. This platform has no DOD/AFM system, so this complete lifter/top-end kit is different from a DOD-delete kit — it includes head gaskets and head bolts because replacing all 16 lifters requires removing the heads.

Parts That Do Not Interchange With Other Generations
Gen III lifters, cam bolt patterns, and timing components are not DOD/AFM-hardware parts and are not interchangeable with Gen IV DOD-delete hardware or Gen V non-DOD lifters/valley covers — this platform simply never had that system.
Tune / Calibration Requirements
Any cam change on this platform requires a matching calibration — idle airflow, idle spark, startup airflow, and the MAF/VE model all need to be built around the new cam. See Build Your Tune.

Gen IV LS DOD Delete Parts
Engines: 5.3L LC9/LMG/LH6, 6.0L LY6/L96/L76, 6.2L L9H/L92/LS3. Vehicles: Silverado/Sierra, Tahoe, Yukon, Suburban, Avalanche, Escalade, Camaro.
Platform note: Many applications in this range use DOD/AFM and may also use VVT. A DOD/AFM delete on this generation always requires the complete parts kit — there is no simplified cam-only kit offered for 2007–2013, unlike 1998/1999–2006. Not every 2007–2013 engine has identical hardware; confirm your exact engine before ordering.
Gen IV VVT delete kit: This platform's complete DOD-delete kit includes a non-VVT front timing cover (L96-style) to eliminate the VVT solenoid, paired with a 3-bolt, 4X reluctor non-VVT cam sprocket. That is the retain/limit/lock/non-VVT strategy supported by the kit data provided — other VVT strategies are not documented here and should be confirmed before ordering.

Parts That Do Not Interchange With Other Generations
The non-DOD lifter trays, DOD/AFM block-off plugs, and non-VVT front timing cover used here are Gen IV-specific and do not fit Gen III (no DOD system) or Gen V (different lifter and valley-cover design).
Tune / Calibration Requirements
A DOD/AFM delete requires the calibration to stop commanding cylinder deactivation and to match the non-VVT hardware if converted. See DOD/AFM Delete Tune and DOD vs AFM Explained.

Gen V EcoTec3 AFM Delete Parts
Engines: 5.3L L83, 6.2L L86 EcoTec3. These are Gen V LT-family engines, not Gen III/IV LS engines. Vehicles: Silverado, Sierra, Tahoe, Yukon, Suburban, Escalade, High Country, Denali, Camaro SS (2016+).
Platform note: Gen V L83/L86 applications use the same LS7-style lifter design as Gen III/IV builds — LS7-style lifters are correct for these engines. The valley cover/VLOM must still be replaced with a non-DOD valley cover, the VVT cam phaser must be locked, and direct injection requires DI-specific calibration. On many vehicles the AC condenser must be removed for cam access (R-1234yf recharge required).
Data status: The specification sheet supplied for this generation was incomplete. The table below lists only the confirmed line items from that sheet. Levels 2/3 and the full parts configurator for Gen V are not yet available and will be added once the complete data is provided — see the Cam Kit Builder below for live, in-stock part options in the meantime.

Parts That Do Not Interchange With Other Generations
The non-DOD/VLOM-delete valley cover and the Gen V-specific camshafts listed above are not interchangeable with Gen III or Gen IV LS parts. LS7-style lifters, however, are correct across Gen III, Gen IV, and Gen V (L83/L86) applications.
Tune / Calibration Requirements
Gen V engines use direct injection and require DI-specific calibration in addition to the AFM-delete and VVT-lockout changes. See Build Your Tune for Gen V-specific tuning.

Choosing A Cam
Common Cam Directions
The right cam depends on your goals, your existing valvetrain, and your vehicle's gearing and converter. This is a starting point, not a spec sheet — final spring, pushrod, converter, gearing, and tuning requirements depend on the exact cam and vehicle combination.
NSR / Factory-Spring Cam
Designed to work with factory valve springs on supported platforms — the basis for a cam-only swap where lifters are healthy.
Mild Daily-Driver Cam
A step up in sound and low-end response while staying easy to live with day to day.
Larger Performance Cam
Requires matched springs and pushrods — moves outside factory-spring-safe territory.

Stage 2 Cam TuneApplication-specific Gen V cams (TSP Gen V Chopacabra, BTR Gen V) are separate parts from their LS-platform namesakes — do not cross-shop Gen V and LS cam part numbers.
Don't Skip This
Tuning Is Part Of The Job
A cam swap, DOD/AFM delete, VVT change, injector change, or major airflow change requires the calibration to match the hardware. The physical kit does not include a tune unless the specific product listing says so.
FAQ
Cam Swap & DOD/AFM Delete Questions
What parts do I need for a 5.3 cam swap?
It depends on your generation. A 1998/1999–2006 5.3L LM7/L59 can qualify for a cam-only NSR cam swap with just the camshaft, retainer plate/bolts, timing cover gasket, front crank seal, balancer bolt, water pump and valve cover gaskets, and fluids. A 2007–2013 or 2014–2018 5.3L always requires the complete parts kit — non-DOD/non-AFM lifters, the correct valley cover or block-off hardware, head gaskets and head bolts, and a full gasket/seal set. See the platform tables above for exact part numbers.
Can I swap a cam without changing lifters?
Only on the 1998/1999–2006 Gen III platform, and only when the existing lifters are healthy and the cam is an NSR-style cam designed for factory springs. On 2007–2013 and 2014–2018 platforms, lifter replacement is always part of the DOD/AFM-delete kit — there is no simplified cam-only kit option on those generations.
What's included in a complete DOD/AFM delete parts kit?
A complete DOD/AFM delete kit for 2007–2013 or 2014–2018 platforms includes a full set of non-DOD lifters and trays, the correct valley cover or block-off hardware, head gaskets and head bolts, timing components, a full gasket/seal set, and fluids — see the platform tables above for the exact parts list and OEM numbers.
Do I need valve springs for a Truck Norris or Chopacabra cam?
It depends on which version of the cam. The NSR versions of these cams are designed to work with factory springs on supported platforms. The full/non-NSR versions require a matched valve spring kit and chromoly pushrods. Check the specific cam listing for your platform.
Can I use LS7 lifters in an L83 or L86?
Yes. LS7-style lifters are correct for L83 and L86 Gen V applications, the same as Gen III/IV LS platforms.
What is the difference between DOD, AFM, and VVT?
DOD (Displacement on Demand) and AFM (Active Fuel Management) are earlier and later GM names for related cylinder-deactivation strategies; the exact hardware and implementation vary by engine. DFM is a newer, more flexible cylinder-deactivation strategy. VVT (Variable Valve Timing) is a separate system that adjusts cam phasing, though some engines have both. See DOD vs AFM Explained for the full breakdown.
Do I need a new oil pump during a cam swap?
Not always. The OEM oil pump is listed as a required part in the complete DOD-delete/lifter-replacement kits in this guide. An upgraded high-volume or high-pressure pump is an optional performance upgrade, not a requirement, unless your specific combination calls for it.
Do I need a tune after a cam swap?
Yes. Any cam change, DOD/AFM delete, or VVT change requires the calibration to be updated to match the new hardware. See Build Your Tune.
What parts are commonly forgotten?
The one-time-use balancer bolt, front crankshaft seal, cam retainer plate and bolts, water pump and timing cover gaskets, oil pickup tube O-ring, oil pan gasket, head bolts (included in DOD-delete and full top-end kits), intake/exhaust/valve cover gaskets, fluids, and the correct valley-cover or DOD-delete hardware are the items most often left off a parts order. See the Parts People Forget section above.
Can J.R. Jones Racing LLC verify my kit by VIN?
Yes — use the VIN Decoder or RPO Code Lookup to confirm your exact engine, or add your VIN in the Cam Kit Builder above so it's attached to your order for verification.
Does a DOD-delete kit include every gasket and bolt?
The complete kits listed on this page are built around the required-parts lists shown in the platform guides above — every gasket, seal, and bolt needed for that kit. Always confirm exact contents on the live product listing before ordering, since options and included items can change.
Can I build my own kit instead of buying the complete package?
Yes. This guide is written so you can source the parts yourself using the part numbers listed, use the Cam Kit Builder to customize a kit with live pricing, or buy one of the three complete matched kits. All three paths use the same underlying parts knowledge.
