Consistent, Fade-Free Damping for Your Rear Suspension
The Bilstein B8 5100 rear shock absorber for the 2023-2026 Chevrolet Colorado and GMC Canyon is a direct-fit monotube shock built to improve ride quality, handling, and comfort over the factory rear shock. BIL33-359849 uses Bilstein's velocity-sensitive digressive piston to automatically adjust damping to changing road conditions, and every B8 5100 application is tuned specifically for its vehicle to deliver the correct feel rather than a generic valving curve.

FAQ
What is the 33-359849?The 33-359849 is a Bilstein B8 5100 rear shock absorber for the 2023-2026 Chevrolet Colorado and GMC Canyon, built as a direct-fit upgrade over the factory rear shock.
Is this shock sold individually or as a pair?This listing is for a single rear shock absorber. Most installations require two, one for each side, so order the correct quantity for your job.
Does this shock provide any additional lift?This B8 5100 rear application is designed as a direct-fit performance replacement rather than a lift shock, so ride height matches the factory specification unless paired with other lift components.
Is this shock adjustable?No. This is a non-adjustable, digressive valved shock tuned by Bilstein specifically for this application.
Does this shock fit both the Colorado and Canyon?Yes. It is designed for the 2023-2026 Chevrolet Colorado Trail Boss and GMC Canyon AT4, Denali, and Elevation trims.
Is there a Proposition 65 warning for this product?Yes. This product carries a California Proposition 65 warning as noted by the manufacturer.
What is different about the B8 5100 series compared to the B8 4600 series?The B8 5100 series is tuned to be more compliant in demanding off-road terrain, while the B8 4600 series is valved for daily-driven, primarily on-road vehicles.
Do I need any special tools to install this shock?Standard hand tools are typically sufficient. No drilling or vehicle modification is required for this direct-fit replacement shock.
