These shock absorbers feature a monotube design which provides consistent fade free performance. All B6 4600 shock absorbers are tuned for each specific application to ensure optimal performance is achieved.
I have updated to Bilstein on another vehicle and experienced very noticeable improvement. This update to front shocks on 07 GMC Canyon off road made the slightly jiggly ride calm. Also cornering was more stable. Well worth the premium price for a premium ride.
