Overview
The Skyjacker BUK3596 is a 3.5 inch rear lift block and U-bolt kit for raising the rear end. Its blocks are packaged in pairs. Year, make and model are absent, so the application must be confirmed separately.
Key features
- 3.5 inch lift height
- Rear blocks in pairs
- Block and U-bolt kit format
- Direct fit is the only fitment wording for this kit.
What a 3.5 inch lift changes
A lift of this size changes how the rear axle sits under the body, which affects driveshaft angle, brake line length and the geometry of the shocks. Larger lifts usually reveal limits in the existing parts, so it helps to measure the current setup before installing new blocks. Expect some changes in ride feel and tire clearance.
Because the axle moves higher, the stock shocks may reach their limits sooner, and the bump stops may need adjusting. Inspect the spring pads and U-bolts for wear before fitting. Retighten all fasteners after the first few drives, and recheck the driveline angles after the work is complete.
- Measure shock length before installation
- Check brake line length after the lift
- Inspect bump stops for clearance

Installation notes
Blocks come in pairs and belong on the rear only; a riser block should never go on the front of the vehicle. Check driveline angles after a lift like this one.
