Questions and answers

Will this fit my RV's slide-out?
Only if your slide uses part 342328 or an exact match on 38-inch stroke, 1-1/2-inch bore and 3/4"-10 thread. Check your owner's manual or the old cylinder's stamping before ordering.
Is it worth buying over a generic cylinder?
A part-number match removes guesswork on stroke and thread, which is where most mismatches happen. At $327.89 at Kunes RVPandA as of November 4, 2026, it sits in the normal range for an OEM-number cylinder.
What is included in the box?
The cylinder and mounting nuts. Reuse your existing pins, hoses and fittings, and plan on new hydraulic fluid for the bleed.
How hard is the install?
Mechanically it is a remove-and-replace job, but you must bleed air from the line and top off fluid. Air in the system causes jerky or incomplete slide travel.
When is it cheapest?
Slide-out parts rarely go on deep discount. Compare the two new listings and watch for free-shipping offers, since a 53-inch cylinder is costly to ship.
Where is the 53" Ret 91" Ext RV Slide-Out Hydraulic Cylinder 342328 cheapest?
