I've been using hockey pucks on top of the blocks that came with the Quickjack. Seems to work but I couldn't decide on the blocks with grooves as there were too many. Would you send me the link for the one's you got and I will try them out. Thanks..I know this is an old thread but...
I have a set. I did the adding wheels mod (as per Youtube) and they work great. I have just used the blocks that came with them and it was fine.
That being said, I picked up a set of 4 blocks on Amazon with the pinch weld groves for around $22 and used them this weekend on 4 different cars (family day for snow tire swaps) and they worked great.
I'll likely use those next time I lift her up.
No but I have 86 on one nowAnyone tried to use a Quickjack 5000 to lift their C4 (1985)?
