Alpine KONI RV Shocks: Front EVO 99 and Rear FSD Applications
Choose Alpine motorhome shocks by the actual chassis and axle application, not just the coach badge. For Alpine Peak, compare KONI EVO 99 front shock 99B 3209 and KONI FSD rear shock 8805 1022. These front and rear references are distinct applications, not interchangeable choices.
The Alpine Peak front and rear references
KONI 99B 3209 is identified as an Alpine Peak front EVO 99 Adjustable RV shock. KONI 8805 1022 is identified as an Alpine Peak rear FSD RV shock. Keep the axle position attached to each number when discussing a replacement. Match the chassis year and suspension before ordering; these parts are not a universal Alpine or Peak application.
Why different axles can use different KONI families
A motorhome's front and rear axles do not necessarily use the same shock design or part family. The listed Alpine Peak combination illustrates that distinction: EVO 99 at the front and FSD at the rear. Choose the engineered application rather than trying to make all four corners carry the same series name. Mounting style, dimensions, and damping requirements matter more than matching the appearance of the shock bodies.
Understand damping before expecting a height change
Shock absorbers control suspension movement after bumps, dips, and other road inputs. They are not the primary components establishing static ride height. If an Alpine sits low, leans while parked, or has an air-suspension height problem, investigate that condition separately. Better damping can help settle repeated motion, but it should not be sold as a cure for failed springs, air leaks, worn steering parts, or an alignment fault.
Use the instructions for the actual KONI model
KONI's RV range includes FSD Gold, Adjustable Red, and EVO 99 Adjustable products, but not every family is available for every Alpine application. Do not assume the adjustment procedure for one KONI design applies to another. Follow the instructions for the installed part number, including any initial setup and installation orientation. A technician should also inspect mounts and bushings so the new shock is attached to sound components.
Describe the coach's behavior precisely
Before choosing parts, distinguish repeated bouncing after a dip from a single harsh impact, steering wander, or persistent leaning. Note whether the problem changes with road speed, cargo, or tank levels. Those observations help separate damping concerns from loading and chassis issues. Use the coach in its normal travel configuration when evaluating the result, and verify tire pressures and vehicle loading against the appropriate specifications rather than compensating for unrelated problems with shock selection.

Frequently asked questions
Which front shock is identified for Alpine Peak?
The listed front reference is KONI EVO 99 Adjustable RV shock 99B 3209.
Which rear shock is identified for Alpine Peak?
The listed rear reference is KONI FSD RV shock 8805 1022.
Can I choose any KONI RV series for my Alpine?
No. Series availability and fitment depend on the chassis and application. Use the confirmed axle-specific part rather than choosing only by series preference.
Will KONI shocks restore a low ride height?
Do not rely on replacement shocks to correct static ride height. Inspect the springs or air-suspension system responsible for supporting the coach.
