1971 Chevrolet Blazer

2010 Gen IV L92 6.2L. Stage 2 VVT cam installed; DOD (Active Fuel Management) system deleted and replaced with standard lifters. Before ordering any valvetrain parts, verify installed cam specs — aftermarket cam dictates spring, pushrod, and lifter requirements.

Kit includes: camshaft, springs with titanium retainers, pushrods, phaser limiter kit, and cam install gasket kit. Fits L99, L96, LY6, LC9, LFA, L76, L94, LC8, LMG. Valvetrain components are matched to this specific grind — do not mix with stock or other aftermarket specs.

Full set of 16 replacement lifters. Fits Gen IV 2006–2014 6.0 / 6.2 — L76, L77, L99, LFA, LZ1, L92, L94. Replaces AFM lifters with standard units. Valley cover configuration and oil pressure requirements change — verify before any engine teardown.

Six-speed manual transmission. When ordering a clutch kit, confirm flywheel diameter and input shaft specs with Tremec. Use Tremec-approved fluid (Pennzoil Synchromesh ATF or equivalent). Fluid capacity: ~3.5 qts.

Ford 9" housing built by Currie. Eaton Truetrac limited-slip differential installed. 4.11 gear ratio — note this before any differential service. When ordering ring & pinion, confirm case spread and carrier bearing size. Use 75W-90 GL-5 gear oil, approx. 2.5 pts.

Tubular steel, black powdercoated. Fits Chevy / GMC. Full kit. Alignment required after replacement. Greaseable ball joints — check fittings every service.

Coilover conversion system. Contact Ridetech with year and current ride height settings for correct replacement springs and shock cartridges. Document current ride height and corner weights before disassembly.

Fits 1960–1972 application. Document adjustment settings and current pinion angle before replacing — arm length directly affects pinion angle and rear wheel alignment.

Front core support crossmember. Fits 1967–1972 application. Welded in place — inspect welds periodically. Document any modifications made during install.

Fits 1967–1972 Chevy C10 / GMC C15 trucks. Power steering — verify pump compatibility and hose routing before replacing. Confirm column shaft coupler type when ordering replacement components.

Fits 1963–1970 Chevy C10, 5×5 bolt pattern. Includes 13" drilled and slotted rotors, 52mm twin piston black calipers, and stainless steel hoses. When ordering replacement pads, confirm 52mm twin piston caliper fitment.

Fits 1963–1987 C10, 5×5 bolt pattern. Includes 12" drilled and slotted zinc coated rotors, black calipers, stainless steel hoses, and external parking brake. Confirm proportioning valve setting after any brake service.

20×8 wheels. Verify bolt pattern and backspacing before mounting new tires or ordering replacements. Lug nut seat type varies by U.S. Mags model — confirm taper angle (typically 60°) before buying lug nuts. Note specific model name for reorder.

245/50R20 fitment. When reordering, confirm load rating and speed rating match. Match DOT date codes across all four tires where possible — aging tires can fail even with remaining tread depth.

Billet aluminum, recessed machined finish. Fits 1967–1972 Chevy C10 / GMC C15. Sold as a pair. Exterior handles only — confirm interior hardware separately if replacing both sides.

Billet aluminum, polished finish with stainless struts. Fits Chevy steel hood. Sold as a pair. When reinstalling, torque mounting hardware evenly to avoid misalignment.

Color name and paint code to be documented. Note the paint brand and mixing ratio for touch-up work. Store a small quantity of mixed paint in a sealed container with the code and date mixed.

Paint system type to be documented (e.g., urethane basecoat, waterborne basecoat, single-stage enamel). Note the product line name and reducer/hardener ratios — these are required for any panel respray or touch-up blending.

Clear coat product to be documented. Note the brand, product name, and part number. Record mix ratio (activator/reducer percentages) and any additives used (flex agent, UV hardener). This is critical for matching gloss level on future panel repairs.

Seats, dash, gauges, steering wheel, and upholstery details not yet recorded. Add part names, brands, and part numbers here for quick reference.

Standalone engine harness built for GM LS swap. Designed to work with the GM ECU on this vehicle. Contact PSI with specific LS variant (displacement and engine code) when ordering replacement or extension harnesses. Harness wiring diagram should be kept in vehicle or build binder.

8-gang relay box kit with wiring accessories. Main fuse and relay distribution panel. Keep wiring diagram in build binder — reference before pulling or adding any circuits. If a relay fails, confirm relay slot and load rating before replacing.

OEM GM ECU paired to the PSI wiring harness. Document the specific ECU part number from the harness documentation or PSI build sheet. Any replacement ECU must be programmed with the current tune — save calibration files to a backup location.

Fits 1963–1972 application. Welded in place — inspect welds periodically, especially after hard use or off-road.

Kit did not fit the Blazer frame as-is — cut and modified to fit, then welded in place. DOM tubing construction. Includes adjustable transmission crossmember. Not a direct bolt-in for this application — if replacing, plan for custom fabrication work. Inspect welds periodically, especially after hard use.
