DOD Delete &
Cam Kit Data
Gen IV LS — every build is heads-off with full DOD delete and LS7 lifters. Three levels. All custom-tuned by Jason in Wilmington, NC.
Heads Off · LS7 Lifters
NSR Cam + DOD Delete
4.8 · 5.3 · 6.0 · 6.2 · Heads removed · All 16 lifters replaced · Full DOD/AFM deleted
The heads come off. All 16 lifters get replaced with LS7 units. The DOD/AFM system is fully deleted with TSP block-off plugs and tray guides. A new timing chain and tensioner go in. A 3-bolt cam gear conversion gets rid of the VVT setup for fixed timing reliability. Then your NSR cam goes in — and we write a custom tune for it. This is the right foundation for any Gen IV LS.
Why NSR at Level 1: The NSR cam is specifically ground to work safely with your factory valve springs — no head machine work, no spring swap needed. You get the sound, the idle, and the power improvement without the extra cost. The DOD delete and LS7 lifter swap happen regardless of which cam you pick.
- Valve spring upgrade — NSR cam is engineered to run on factory springs
- Chromoly pushrods — factory pushrods retained, NSR spec does not require replacement
- Valve stem seals — heads reinstalled with factory seals if in good condition
- Long tube headers — available in Level 3
NSR = No Springs Required. Both cams are ground to work safely with your factory valvetrain — no spring swap, no chromoly pushrods, no valve stem seals needed. The DOD delete and LS7 lifters still happen either way.

Bigger Cam · Springs
Chromoly Pushrods · No Headers
4.8 · 5.3 · 6.0 · 6.2 · Non-NSR Cam · Matched Spring Kit · Chromoly Pushrods · Valve Stem Seals
Everything in Level 1 — plus the step up to a non-NSR cam. More aggressive lift and duration than the NSR versions, matched with the spring kit and chromoly pushrods the cam needs to run correctly. The valvetrain is built to support the cam for the long haul. Headers not included here — if you want them, see Level 3.
Why Level 2 over Level 1: The non-NSR cam gives you more lift, more duration, and more top-end pull. Factory springs can't safely handle that stress long-term — so we do the spring upgrade, chromoly pushrods, and valve seals all at the same time while the heads are already off. It's the correct way to run a bigger cam on a Gen IV.
- Speed Engineering long tube headers — available in Level 3
- Catless Y-pipe — available in Level 3

Headers & Y-Pipe
4.8 · 5.3 · 6.0 · 6.2 · Non-NSR Cam · Springs · Chromoly · Speed Engineering Long Tube Headers · Catless Y-Pipe
The complete package. Everything in Level 2 — plus Speed Engineering long tube headers and a catless Y-pipe, all installed together and tuned as one complete system. Headers go on while the engine is already open, which saves significant labor versus doing it separately later. One build, done right, written into one custom tune.
Why do headers now instead of later: When the engine is already apart for the cam and lifter job, header install is far less labor. Coming back later to add headers on an assembled engine is a bigger job — costs more and means pulling things apart again. Do it once here and save.

2007–2013 GM 4.8, 5.3, 6.0, and 6.2 DOD Delete & Cam Swap Packages in Wilmington, NC
Silverado · Sierra · Tahoe · Yukon · Suburban · Avalanche · Escalade · Camaro · Gen IV LS
If you are searching for a 2007–2013 Silverado DOD delete, 5.3 AFM delete near Wilmington NC, Tahoe lifter failure repair, Yukon DOD delete, Sierra cam swap, Escalade 6.2 AFM delete, Texas Speed Chopacabra install, BTR Truck Norris cam swap, or custom HP Tuners tuning for a Gen IV LS truck or SUV, this page is built for exactly that. These 2007–2013 GM LS engines are some of the most failure-prone AFM and DOD platforms on the road, and the only right way to fix them is to open them up, replace the valvetrain correctly, delete the system fully, and tune the vehicle for the finished combination.
The 2007–2013 GM LS platform is where AFM / DOD lifter failure becomes a major problem. That means ticking lifters, wiped cam lobes, rough idle, recurring check engine lights, random misfires, and eventually major engine damage.
That is why every package on this page is a heads-off build with full DOD delete. No heads-on shortcut packages. No partial fixes. No “just throw a cam in it” installs.
- Ticking or tapping lifter noise at idle or on cold start
- P0300 random misfire or cylinder-specific misfire codes
- Collapsed AFM lifter and wiped camshaft lobe
- Recurring check engine light after temporary repairs
- Rough idle, power loss, or poor throttle response
- Oil consumption and long-term damage tied to AFM-equipped engines
Level 1 vs Level 2 vs Level 3: Level 1 is the full DOD delete and LS7 lifter foundation with an NSR cam. Level 2 steps up into a bigger non-NSR cam with matched springs, chromoly pushrods, and valve seals. Level 3 adds Speed Engineering long tube headers and a catless Y-pipe so the whole combination gets built and tuned together at once.
Cape Fear Cams provides 2007–2013 GM AFM delete, DOD delete, lifter failure repair, and Gen IV LS cam swap packages in Wilmington, North Carolina for customers in Wilmington, Leland, Castle Hayne, Hampstead, Burgaw, Jacksonville, Carolina Beach, Kure Beach, Surf City, Southport, Shallotte, Raleigh, Fayetteville, and surrounding areas. If you have a Silverado 5.3 tick, Tahoe AFM failure, Yukon 6.2 DOD issue, Sierra lifter collapse, or Escalade camshaft damage, this page is meant to answer those searches directly and explain the complete repair path clearly.
Common searches that should land on this page include Silverado AFM delete Wilmington NC, 5.3 DOD delete near me, Sierra 5.3 lifter failure, Tahoe cam and AFM delete package, Yukon Denali 6.2 DOD delete, Escalade 6.2 lifter repair, LC9 DOD delete, LMG AFM delete, LH6 lifter replacement, LY5 cam swap, L92 cam package, Gen IV LS truck cam swap, Texas Speed cam install, BTR cam install, HP Tuners Gen IV LS tune, and full DOD delete with LS7 lifters. That is exactly the work this page represents.
Call or text Jason if you need help choosing between Level 1, Level 2, or Level 3.
