COMPLETE TSP 224R CAM KIT – Trusted by LS builders nationwide, this kit includes everything a professional installer would spec: Texas Speed TSP 224R Camshaft (224/224, .600"/.600", 112 LSA, 110 ICL, 3-Bolt, Made in USA), 16 Genuine GM ACDelco Performance 12499225 Hydraulic Roller Lifters (Made in USA), .625" Beehive Valve Springs with Steel Retainers and Locks, Hardened Chromoly Pushrods (7.400", 0.080" wall), 2 Sets of USA-Made Elgin or Fel-Pro Head Bolts, and a Full Upper MLS Head Gasket Set (Made in USA). The most complete TSP 224R cam kit for 4.8L and 5.3L LS cam swaps — one order, one shipment, zero guesswork.
EXCELLENT DRIVABILITY WITH POWER GAINS YOU ACTUALLY FEEL – The TSP 224R is without a doubt one of the most popular camshafts Texas Speed offers for LS engines — delivering solid power gains across a broad 1,400–6,500 RPM operating range with excellent drivability and a good lope at idle that lets everyone nearby know this engine has been properly built. For customers looking for a smaller camshaft that packs a big punch the TSP 224R is pretty hard to beat.
VERIFIED FITMENT – Built for 1999–2013 GM 4.8L and 5.3L Vortec V8 LS cam swap engines (LR4, LM7, L59, LM4, L33, LH6, LC9, LY5, LMG).

Please verify bolt pattern configuration prior to installation.
GENUINE GM ACDELCO PERFORMANCE 12499225 ROLLER LIFTERS – MADE IN THE USA – Not generic offshore substitutes. These are the real GM ACDelco Performance part number 12499225 hydraulic roller lifters, manufactured right here in the United States — the same trusted lifters used in OEM performance applications. The TSP 224R 4.8L and 5.3L LS cam swap demands quality lifters and these are the ones serious LS builders trust. We don't cut corners on the parts that keep your valvetrain alive.
MATCHED .625" BEEHIVE SPRINGS WITH STEEL RETAINERS + LOCKS + HARDENED PUSHRODS – Purpose-matched to the TSP 224R's .600"/.600" lift profile for correct spring pressure and reliable high-RPM operation across all 4.8L and 5.3L cathedral port LS engine families. Steel retainers and locks secure everything properly under sustained load. Hardened chromoly pushrods at 7.400" length and 0.080" wall thickness eliminate flex under load. Stock pushrods flex on every LS cam swap — these don't.
USA-MADE ELGIN OR FEL-PRO HEAD BOLTS + MLS HEAD GASKETS – When it comes to the parts that seal and fasten your 4.8L or 5.3L LS cam swap build, we don't compromise. Elgin and Fel-Pro are two of the most trusted American engine component manufacturers in the industry. The full upper MLS head gasket set provides superior crush resistance, better sealing under high cylinder pressure, and long-term reliability that composite gaskets simply cannot match — proudly made in the USA and precision matched for cathedral port 4.8L and 5.3L LS engines.
FEEL THE DIFFERENCE FROM THE FIRST STARTUP – Fire up the TSP 224R and enjoy a confident lope at idle that immediately separates this 4.8L or 5.3L LS from every stock engine on the road. Around town the throttle response is sharper and the pull through the midrange is noticeably stronger. Get on the highway and the broad 1,400–6,500 RPM powerband delivers real performance gains on every drive. Cam, lifters, springs, pushrods, head bolts, and MLS head gaskets all spec'd to work together in one box. Big power. Broad powerband. Built for the street.
