have a 4.5 inch rough country lift, want to add coil spacers and new leaf springs. but I dont want to drop all of that money into a slip yoke and a new driveshaft. can I get away without buying them?

Atmos

get away? no. you'll need an SYE. custom driveshaft? absolutely not. take your front driveshaft off and install it in the rear with your new SYE. go find another front driveshaft at the junk yard

You can add shims in the rear an u can get away with out running the sye but its not the way to do it.. but it deff can be done

Adding shims only adjust pinion angle.

The factory drive shaft and slip yoke can only take so much angle. You can literally snap your t case main shaft is you wheel it hard and have to much lift

sneakyjap96

Adding the angle will stick the slip yoke in farther so that way its easier on it. I never disagreed just tired of people saying you cant when you can. Me personally was worried about driving my xj with the slip yoke at 6 in lift so should you run sye yes is it needed to where you can drive no recommended to wheel that way hell no

Atmos

saying you can't wheel without the SYE is the same as saying must have an SYE at 5.5"

same difference

sneakyjap96

No cause who says the guy is going to wheel lol maybe a mall crawler

Do it right. Get a sye. Ds can be from the yard.

I might put shims in as well. What if I used the front ds for the rear and getting a new front ds from a yard?

sye and a donor shaft was a GOD SENT for me, I had TERRIBLE vibes!

For $200, in my case, I dont understand why no one likes to spend the money. Rugged Ridge sye $160, JY shaft $40. I know others like different brands of sye kit that are more expensive, but the RR sye is doing the job.

IMO the cost for doing the SYE is from the custom shaft like a Toms Woods ($400) not the sye kit itself.

SYE ranks #3 in mods for me, only behind my shackle relocation kit, and headlight/harness upgrade.

The Iron Rock Offroad Hack & Tap SYE is $100. A junkyard driveshaft is around $30.
