CLEARANCE L83/L86 Accessory Drive Bracket for GM V8 Engines
When swapping a Gen 5 L83 or L86 into a truck frame the CLEARANCE-L83/L86 Accessory Drive Bracket simplifies installation by bringing alternator, power steering pump and AC compressor mounts into a single precise assembly. It aligns directly with factory bosses to preserve correct belt path and tension right from the initial installation. With automotive grade steel construction this clearance bracket resists bending under load and maintains pulley alignment during hard acceleration and towing. Offered at a reduced price despite minor surface marks it delivers reliable performance for budget conscious builders.
Optimized Belt Path for Reliable Tension Retention
The bracket preserves the exact geometric relationship among the alternator, power steering pump and AC compressor pulleys to match factory belt routing. It holds each pulley at factory specified center-to-center distances to maintain ideal belt wrap angles and avoid lateral drift. This precision prevents premature cracking or glazing under heavy load and ensures belt life is maximized. By locking in correct tension from the first startup, it supports reliable charging output and consistent air conditioning performance. Builders skip time-consuming shim adjustments and repeated test fits, gaining immediate confidence in accessory operation during towing and hard acceleration.
Rigorous Steel Construction for Sustained Alignment
The bracket is formed from premium grade steel plate that meets stringent automotive fatigue standards. Laser-cut flanges and precision-welded seams deliver consistent rigidity that resists deflection under heavy load and harsh vibration. Strategic weld reinforcement around critical bosses maintains pulley alignment even after repeated thermal and torque cycles. Its design balances strength with weight savings to avoid overloading the crank accessory drive. This robust construction extends service life by preventing alignment-induced wear on both the bracket and the belt.
Comprehensive Mounting Kit Ensures Rapid Assembly
Included in the package is a full set of OEM-matched bolts, spacers and lock washers, all plated for corrosion resistance and engineered to factory length specifications. An illustrated guide outlines the proper bolt sequence and torque values to secure each accessory mount in the correct order. This complete mounting kit prevents common pitfalls like missing hardware or mismatched fastener grades. Technicians benefit from fewer trips to the parts bin and reduced risk of thread stripping or bolt galling. The result is a faster, error free installation that frees builders to focus on other key tasks in the swap.
Certified Fit and Finish Despite Cosmetic Marks
Although marked as a clearance item, every bracket undergoes the same rigorous dimensional inspection and strength testing as full retail units. Visual checks confirm that any minor surface blemishes are purely cosmetic and do not impair structural integrity or fitment. Critical features such as hole spacing and flange angles are verified within factory tolerance using calibrated measuring tools. This quality control process ensures each bracket mates perfectly to Gen 5 L83 and L86 engine blocks without modification. The clearance status simply passes on cost savings to builders while preserving engineering precision.
