COMPLETE TSP 224R CAM KIT – Everything a professional installer would spec in one box: Texas Speed TSP 224R Camshaft (224/224, .600\"/.600\", 112 LSA, 110 ICL, 3-Bolt, Made in USA), 16 Premium LS7-Style Roller Lifters with Trays, PAC1219-Style .625\" Beehive Valve Springs, Hardened Chromoly Pushrods (7.400\", 0.080\" wall), Premium Valve Stem Seals, Front Timing Cover Gasket Set, 2 LS1-Style MLS Head Gaskets, and a Premium LS Rocker Arm Trunnion Upgrade Kit. The most complete TSP 224R cam kit for 5.7L, 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 LS1, LS2, and LS6 cathedral port 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 – Best suited for 5.7L, 4.8L, and 5.3L cathedral port LS cam swap engines. Compatible with 1997–2013 GM 5.7L, 4.8L, and 5.3L LS cam swap engines (LS1, LR4, LM7, L59, LM4, L33, LH6, LC9, LY5, LMG). Fits Camaro, Corvette, Firebird, Trans Am, Pontiac GTO, Pontiac G8, Silverado, Sierra, Tahoe, Suburban, Yukon, Escalade, and Avalanche. LS1-style MLS head gaskets precision matched to cathedral port cylinder heads. Works well with factory torque converters on the 112 LSA. Please verify bolt pattern configuration prior to installation.
16 PREMIUM LS7-STYLE ROLLER LIFTERS WITH TRAYS – LS7-style lifters are wider, more stable, and built to handle aggressive cam profiles like the TSP 224R without failure. Lifter trays are included to keep everything properly oriented during installation — the same setup serious LS builders and professional engine shops spec every time for a complete 5.7L LS1, 4.8L, or 5.3L LS cam swap. Don\'t cut corners on the parts that keep your valvetrain alive.
MATCHED PAC1219 .625\" BEEHIVE SPRINGS + HARDENED PUSHRODS + VALVE STEM SEALS – Purpose-matched to the TSP 224R\'s .600\"/.600\" lift profile for correct spring pressure and reliable high-RPM operation. The PAC1219 is a drop-in high performance spring kit for all OE LS cylinder heads rated for up to .600\" lift. Hardened chromoly pushrods at 7.400\" length and 0.080\" wall thickness eliminate the flex that stock pushrods cannot handle under a performance cam. Stock pushrods flex under load — these don\'t. Premium valve stem seals and front timing gasket included for a complete professional LS cam swap install.
LS1-STYLE MLS HEAD GASKETS – Two premium Multi-Layer Steel head gaskets precision matched to the cathedral port cylinder heads found on 5.7L, 4.8L, and 5.3L LS engines. MLS is the gold standard for sealing LS performance builds — superior crush resistance, better sealing under high cylinder pressure, and long-term reliability that composite gaskets simply cannot match. The right gasket for your 5.7L LS1 cam swap, 5.3L lopey truck build, or 4.8L LS performance upgrade.
PREMIUM LS ROCKER ARM TRUNNION UPGRADE KIT – DO NOT SKIP THIS ON YOUR LS BUILD – The factory LS rocker arm trunnion is one of the most well-known failure points in the entire LS engine family — and one of the most searched LS upgrades on and Amazon for good reason. When the factory pressed-in needle bearings fail they send small bearings through the entire engine causing catastrophic damage to your 5.7L LS1, 4.8L, or 5.3L LS build. This premium LS Series retrofit trunnion kit converts your stock LS rocker arms into captured roller bearing rocker arms — eliminating the factory failure point entirely. The upgraded captured roller bearings allow for smooth reliable rotation and deliver significantly more stability at higher RPM than the factory design. We use these trunnion kits in everything from stock 4.8L daily drivers all the way up to 1,000+ horsepower turbo motors — that is how critical this upgrade is on every single 5.7L LS1, 4.8L, or 5.3L LS cam swap build.
FEEL THE DIFFERENCE FROM THE FIRST STARTUP – Fire up the TSP 224R and enjoy a confident lope at idle that immediately separates this 5.7L LS1, 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. The perfect complete LS cam swap kit for 5.7L LS1, 4.8L, and 5.3L builds — cam, LS7 lifters, springs, pushrods, head gaskets, timing gasket, and trunnion upgrade kit all spec\'d to work together in one box. Big power. Broad powerband. Built for the street.
