That centers the rear tires in the wheel opening, adds clearance and lengthens the wheelbase, which TeraFlex says helps when climbing. Rear Alpine mid arm stretch brackets and rear upper coil spring relocation brackets keep the springs vertical so they don't bow. The 2\" is wheelbase stretch, not lift: lift coil springs and longer shocks are required and not included.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eUp to 2\" more wheelbase\u003c\/strong\u003e\u003cbr\u003eMoves the rear axle back as much as 2\", which TeraFlex says improves climbing on steep terrain.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCenters the rear tires\u003c\/strong\u003e\u003cbr\u003ePuts the rear wheels in the middle of the opening for more tire clearance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSprings stay vertical\u003c\/strong\u003e\u003cbr\u003eRelocation brackets keep the rear coil springs upright to prevent bowing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAlpine adjustable arms\u003c\/strong\u003e\u003cbr\u003eBuilt around TeraFlex's Alpine rear arms, sold here as a 4-arm rear kit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFactory or high-line flares\u003c\/strong\u003e\u003cbr\u003eDesigned with high-line fenders in mind, but TeraFlex says it also works with factory flares.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePairs with your lift\u003c\/strong\u003e\u003cbr\u003eNeeds lift coil springs and longer shocks, both sold separately.\u003c\/p\u003e\n\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cstyle\u003e.pt-fit{margin:10px 0 4px;position:relative}.pt-fit\u003einput{position:absolute;width:1px;height:1px;opacity:0;margin:0;pointer-events:none}.pt-fit__tabs{display:flex;flex-wrap:wrap;gap:6px;margin:0 0 12px;padding:0}.pt-fit__tabs label{display:inline-flex;align-items:center;gap:7px;cursor:pointer;padding:6px 14px;border:1px solid #e2e4e6;border-radius:999px;background:#f2f3f4;color:#4a5057;font-weight:700;line-height:1.35}.pt-fit__tabs label\u003espan{display:inline-flex;align-items:center;justify-content:center;box-sizing:content-box;min-width:1.5em;height:1.5em;padding:0 .3em;line-height:1;font-size:.75em;font-weight:700;color:#8a9099;background:#ffffff;border-radius:999px}.pt-fit__tabs label:hover{background:#e8eaec}.pt-fit__p{display:block}#fit-1257100 .pt-fit__p{display:none}.pt-fitw{overflow-x:auto;border:1px solid #e6e6e6;border-radius:8px;background:#ffffff;margin:10px 0 4px}.pt-fitw table{display:table;table-layout:fixed;width:100%;margin:0;border-collapse:separate;border-spacing:0;border:none;min-width:560px}.pt-fitw caption{caption-side:top;text-align:left;padding:0 0 8px;font-weight:700;letter-spacing:.06em;text-transform:uppercase;color:#8a9099;font-size:.8em}.pt-fit .pt-fitw caption{position:absolute;width:1px;height:1px;padding:0;overflow:hidden;clip-path:inset(50%);white-space:nowrap}@media print{.pt-fit .pt-fitw caption{position:static!important;width:auto!important;height:auto!important;clip-path:none!important;padding:0 0 8px!important}}.pt-fitw th{background:#141414;color:#ffffff;text-align:left;padding:11px 14px;font-weight:700;font-size:12px;letter-spacing:.09em;text-transform:uppercase;border:none;white-space:nowrap}.pt-fitw td{padding:11px 14px;border:none;border-bottom:1px solid #ececec;background:#ffffff;vertical-align:top}.pt-fitw tbody tr:nth-child(even) td{background:#f7f7f7}.pt-fitw tbody tr:last-child td{border-bottom:none}.pt-fitw td.y{font-weight:700;white-space:nowrap}.pt-fitw td.b{white-space:nowrap}.pt-fitw td.n{color:#5a6067;font-size:.92em}.pt-fitw td.e{color:#c4c8cc}#fit-1257100\u003e.pt-fit__panels\u003e.pt-fit__p:first-of-type{display:block}#fit-1257100\u003einput:checked~.pt-fit__panels\u003e.pt-fit__p{display:none}@media print{#fit-1257100 .pt-fit__tabs{display:none}#fit-1257100 .pt-fit__p{display:block!important}#fit-1257100 .pt-fitw{overflow:visible!important}#fit-1257100 .pt-fitw table{min-width:0!important}}\u003c\/style\u003e\u003cdiv class=\"pt-fitw\"\u003e\u003ctable\u003e\n\u003ccaption\u003eJeep\u003c\/caption\u003e\n\u003ccolgroup\u003e\n\u003ccol style=\"width:22%\"\u003e\n\u003ccol style=\"width:28%\"\u003e\n\u003ccol style=\"width:12%\"\u003e\n\u003ccol style=\"width:38%\"\u003e\n\u003c\/colgroup\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eYears\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eBed\u003c\/th\u003e\n\u003cth\u003eNotes\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd class=\"y\"\u003e2007-2018\u003c\/td\u003e\n\u003ctd\u003eWrangler\u003c\/td\u003e\n\u003ctd class=\"b\"\u003e\u003c\/td\u003e\n\u003ctd class=\"n\"\u003eJK\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c\/div\u003e\u003cdiv style=\"background:#faf7f7;border-left:4px solid #ba232a;border-radius:0 8px 8px 0;padding:14px 16px;margin:12px 0;\"\u003e\n\u003cp style=\"margin:0 0 8px;\"\u003e\u003cstrong\u003eCheck your Jeep:\u003c\/strong\u003e Wrangler JK or JK Unlimited, 2007-2018; lift coil springs and longer shocks in place or planned.\u003c\/p\u003e\n\u003cp style=\"margin:0;\"\u003e\u003cstrong\u003eNot for:\u003c\/strong\u003e JL or JT models.
