Description
F800GS Shock Bolt Kit
Designed specifically for BMW F800GS and F800GS-A models (all years), this F800GS shock bolt kit helps riders avoid or address the common issue of bent upper shock bolts under demanding off-road conditions. By upgrading to a hardened F800GS shock bolt, you’ll significantly reduce the risk of damage to your bike’s suspension and frame.
Kit Contents
- 12x120mm Upper F800GS Shock Bolt (Grade 12.9, Black Oxide Finish)
- 3 mm Thick Washer for proper spacing
Key Features
- Stronger Than OEM
- Replaces the original Grade 10.5 bolt with a hardened Grade 12.9 shock bolt, greatly minimizing bending.
- Proper Fit
- The 3 mm washer ensures correct torque and spacing before the shock bolt shoulder meets the round “nut.”
- Improved Durability
- Withstands heavy off-road loads that commonly bend or damage a standard F800GS shock bolt.
Installation Instructions
- Upper Bolt
- Place the 3 mm washer on the F800GS shock bolt before installation.
- Lightly grease the washer and bolt head for accurate torque (do not grease threads).
- Torque the F800GS shock bolt to 100 Nm for a secure fit.
- Lower Bolt (OEM Recommended)
- BMW’s lower bolt has a unique head diameter; retain or replace it with OEM only.
- If reusing the OEM bolt, lightly grease the shaft (not the threads) and apply high-strength threadlocker (e.g., red Loctite).
- Torque the lower bolt to 100 Nm.
Additional Support
- Shock Support Bracket
- Combine this shock bolt kit with a shock support bracket for maximum reinforcement, strengthening the upper mount by over 70%.
- Disclaimer
- BestRest Products assumes no liability for modifications to your motorcycle’s suspension components. The shock bolt upgrade is the best option until BMW revises its design.
Why Upgrade?
- A bent shock bolt can lead to severe, costly frame damage.
- Installing a hardened shock bolt alone improves mounting strength by roughly 25%.
- Pairing the bracket and shock bolt delivers even greater protection, giving you peace of mind during rugged off-road adventures.
