Unlock Massive Power & Aggressive Choppy Idle: Ultimate Sloppy Stage 2 Camshaft Overhaul Kit for GM Gen 3 / Gen 4 LS V8
Are you ready to wake up your GM LS V8 and get that legendary, aggressive "choppy" idle everyone loves? The Sloppy Stage 2 camshaft profile (228/230 @.050", .585"/.585" Lift, 112 LSA) is arguably the most popular, proven, and cost-effective performance upgrade for 4.8L, 5.3L, 5.7L, and 6.0L LS builds. Designed to unlock massive mid-to-high RPM horsepower gains (operating range of 2200 to 5400 RPM), this heavy-duty cam upgrade is perfect for rowdy naturally aspirated street cars, heavy-hitting turbo setups, or aggressive LS swaps.
Dropping a big camshaft into an LS engine requires upgrading the entire valvetrain to prevent catastrophic valve float and lifter failure at high RPMs. Sourcing perfectly matched springs, heavy-duty pushrods, lifters, and a high-volume oil pump separately is incredibly expensive and frustrating. This Ultimate Sloppy Stage 2 Overhaul Kit takes the guesswork completely out of your build by packaging the E1840P-spec camshaft with legendary PAC-1218 beehive springs, high-strength chromoly pushrods, premium hydraulic roller lifters, and the essential M295 high-volume oil pump for ultimate engine protection.
Key Features & Included Components:
Sloppy Stage 2 Camshaft (E1840P): 228/230 @.050", .585"/.585" Lift, 112 LSA, 108 Intake Centerline, 3-bolt gear attachment. Delivers a highly aggressive idle and massive mid-to-high RPM power bands.
PAC-1218 Beehive Valve Springs: Includes 16x drop-in premium beehive springs rated for up to .600" lift to completely eliminate dangerous valve float under heavy boost or high RPMs.
Heavy-Duty Valvetrain Upgrades: Comes complete with 16x 7.400" high-strength chromoly pushrods and 16x HL2148S premium hydraulic roller lifters (along with guide trays) to ensure absolute valvetrain stability.
Lubrication & Timing Overhaul: Protects your critical engine bearings with an upgraded M295 high-volume oil pump. This master kit also bundles a complete engine timing chain kit and 16x fresh valve stem seals for a perfect top-end seal.
(⚠️ CRITICAL FITMENT & INSTALLATION NOTE: This performance camshaft kit is engineered for GM Gen 3 and Gen 4 LS-based V8 engines utilizing a standard 3-bolt cam gear attachment. Custom ECU tuning is ABSOLUTELY REQUIRED after installation to ensure proper idle, fueling, and drivability. Please verify your block's generation and camshaft gear bolt pattern before purchasing.)
Engineered to meet or exceed strict high-performance standards for extreme durability on the street, strip, or track. Upgrade your LS valvetrain the right way with BTSCAR's matched performance components and dominate the competition with absolute confidence.
