Replacement Bearings, Races and Seals for 2009 K-Z Spree 5TH Wheel  

The best replacement pin box for the Lippert 1621 on your Grand Design Reflection 303RLS is the Curt Flex Air. This pin boxes has an air spring and shock absorber which will reduce the back and forth chucking (stopping and taking off) and lower the…

If you're comparing the Tailair Rota-Flex that replaces a 1621 or 1621HD Lippert pin box, part #LC328330, with the MORryde equivalent (part #MR64VR for 5th-wheel trailers with up to 11,500-lb GVWR, and part #MR84VR for 5th-wheel trailers with…

Since your GVWR is 11,400 lb the correct rated MorRyde pin box would be the part #MR64VR which is rated for up to 11,500 lb GVWR. While you are close to that you are under that number so it would work really well.

I spoke to my contact at Torklift and he informed me that the left to right width of the mounting bracket of the Torklift Glowstep Revolutions like the part #TLA8003 is 27-1/2 inches and the front to back depth is 12 inches. All of the Torklift steps…

My TorkLift contact advised that on their GlowStep Revolution Scissor Step #TLA8003 the distance from the top of the frame bracket down to the top step is 7-inches. Unlike most others this step offers some adjustability. If you are at a campsite that…

The TorkLift GlowStep Revolution Scissor Steps w/ Landing Gear #TLA8003 is designed for entry height between 25-1/2 and 36 inches. This is to the door threshold not the bottom of the compartment. If that is the case, then it will be a great option…

I would be happy to help you figure out the correct TorkLift GlowStep Revolution Scissor Steps for your 2012 Rockwood 8312SS, but unfortunately I do not have a list that has the correct step for your trailer. To determine the correct steps you will…
