maXpeedingrods Rear Shock Absorber Set for Chevy Silverado 1500 1999–2006 — 2pc ENEOS-damped Rear Shocks

If your truck is showing signs of sagging, excessive bounce, or poor handling in the rear, swapping to a matched pair of reliable shocks is one of the fastest ways to regain confidence on the road. The maXpeedingrods 37150 shocks are specified for late‑1990s to mid‑2000s Silverado and Sierra 1500 trucks and come as a two-shock set intended to directly replace several OEM and aftermarket reference numbers. They use upgraded ENEOS damping oil and have undergone extensive fatigue testing to ensure consistent damping performance across a wide temperature range.

How do these shocks improve daily driving and towing?

Replacing worn rear shocks tightens body control, cuts down rear-end bounce over bumps, and helps keep tires planted during acceleration and braking. Better damping translates to improved comfort and more predictable handling when hauling cargo or towing light loads.

• Reduces rear oscillation after hitting bumps for smoother ride quality
• Improves braking stability and reduces squat during acceleration
• Maintains tire contact to extend tread life and enhance traction

Will these fit my Chevy Silverado or GMC Sierra?

These shocks are engineered as direct-fit replacements for Chevy Silverado 1500 and GMC Sierra 1500 model years 1999–2006, plus the 2007 Classic versions. They are sold as a pair to replace both rear units and match factory mounting points and stroke specifications.

• Compatibility: Silverado/Sierra 1500 (1999–2006) and 2007 Classic rear
• Listed cross‑reference numbers included for installer verification
• Sold as 2x rear shock absorbers — ready for bolt‑on installation

What materials and testing back up the performance?

maXpeedingrods uses ENEOS damping oil in the shock internals for stable viscosity from cold to hot conditions, reducing the chance of piston clogging and preserving consistent damping. The assemblies were fatigue tested millions of cycles to check for leakage and ensure the damping force remains within acceptable attenuation limits.

• High‑quality ENEOS damping oil for reliable temperature performance
• 3 million fatigue cycles with no oil leakage in test results
• Damping attenuation controlled to maintain consistent feel over time

How does installation, warranty, and support work?

The shocks arrive as two rear units and are intended for straightforward bolt-on replacement using your truck’s existing upper and lower mounts. maXpeedingrods provides lifetime technical support and a one-year limited warranty for manufacturer-related defects from the purchase date.

• Package contains 2 rear shock absorbers with reference cross numbers
• Lifetime technical assistance and 1‑year limited warranty included
• Recommended: inspect mounting hardware and bushings during replacement

Who is this for: These maXpeedingrods 37150 rear shocks are aimed at Silverado and Sierra owners who want a cost-effective, direct-replacement upgrade to restore rear-end control — ideal for daily drivers, light-duty towing, and trucks with worn or leaky original rear shocks. If you need reliable damping across a broad temperature range and confidence backed by extensive fatigue testing and post-sale support, this two-piece set is a practical choice.
