Installation Notes

Verify rear mounting style and dimensions before installation: compressed length 14.29 in, extended length 22.68 in, and stroke length 8.39 in. Confirm the lower mount type E2 (12x55) and upper mount type S1 (10 mm) match the vehicle’s original hardware layout. Dust cover is not included.

For best results, replace shocks in axle pairs and inspect related suspension components for wear before final assembly. Part number 3430110 should be matched to the listed rear fitment only.
